The P5400 portable radio has been tested and complies with the FCC RF exposure limits for 
“Occupational Use Only.”  In addition, this M/A-COM radio complies with the following Standards and 
Guidelines with regard to RF energy and electromagnetic energy levels and evaluation of such levels for 
exposure to humans: 
• FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compliance with FCC Guidelines for 
Human Exposure to Radio Frequency Electromagnetic Fields. 
• American National Standards Institute (C95.1 – 1992), IEEE Standard for Safety Levels with Respect 
to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz. 
• American National Standards Institute (C95.3 – 1992), IEEE Recommended Practice for the 
Measurement of Potentially Hazardous Electromagnetic Fields – RF and Microwave. 
2.1 RF EXPOSURE GUIDELINES 
CAUTION  
To ensure that exposure to RF electromagnetic energy is within the FCC allowable 
limits for occupational use, always adhere to the following guidelines: 
• DO NOT operate the radio without a proper antenna attached, as this may damage the radio and may 
also cause the FCC RF exposure limits to be exceeded. A proper antenna is the antenna supplied with 
this radio by M/A-COM or an antenna specifically authorized by M/A-COM for use with this radio. 
(Refer to Table 6-1.) 
• DO NOT transmit for more than 50% of total radio use time (“50% duty cycle”). Transmitting more 
than 50% of the time can cause FCC RF exposure compliance requirements to be exceeded. The radio 
is transmitting when the “TX” indicator appears in the display. The radio will transmit by pressing the 
“PTT” (Push-To-Talk) button. 
• Always transmit using low power when possible. In addition to conserving battery charge, low power 
can reduce RF exposure. 
• ALWAYS use M/A-COM authorized accessories (antennas, batteries, belt clips, speaker/mics, etc). 
Use of unauthorized accessories may cause the FCC Occupational/Controlled Exposure RF 
compliance requirements to be exceeded. (Refer to Table 2-1.) 

MM-012099-001, Rev. B 
12 
• As noted in Table 2-1, ALWAYS keep the device and its antenna AT LEAST 1.1 cm (0.43 inches) 
from the body and at least 2.5 cm (1.0 inch) from the face when transmitting to ensure FCC RF 
exposure compliance requirements are not exceeded. However, to provide the best sound quality to 
the recipients of your transmission, M/A-COM recommends you hold the microphone at least 5 cm (2 
inches) from mouth, and slightly off to one side.

The information in this section provides the information needed to make the user aware of RF exposure, 
and what to do to assure that this radio operates within the FCC RF exposure limits of this radio. 
2.2 ELECTROMAGNETIC INTERFERENCE/COMPATIBILITY 
During transmissions, this M/A-COM radio generates RF energy that can possibly cause interference with 
other devices or systems. To avoid such interference, turn off the radio in areas where signs are posted to 
do so. DO NOT operate the transmitter in areas that are sensitive to electromagnetic radiation such as 
hospitals, aircraft, and blasting sites. 

MM-012099-001, Rev. B

3 OPERATING TIPS 
Antenna location and condition are important when operating a portable radio. Operating the radio in low 
lying areas or terrain, under power lines or bridges, inside of a vehicle or in a metal framed building can 
severely reduce the range of the unit. Mountains can also reduce the range of the unit.  
In areas where transmission or reception is poor, some improvement may be obtained by ensuring that the 
antenna is vertical. Moving a few yards in another direction or moving to a higher elevation may also 
improve communications. Vehicular operation can be aided with the use of an externally mounted 
antenna.  
Battery condition is another important factor in the trouble free operation of a portable radio. Always 
properly charge the batteries.  
3.1  EFFICIENT RADIO OPERATION 
For optimum audio clarity at the receiving radio(s), hold the portable radio approximately two inches 
from your mouth and speak into the microphone at a normal voice level.  
Keep the antenna in a vertical position when receiving or transmitting a message.  
Do not hold the antenna when receiving a message and, especially, do not hold when transmitting a 
message.  
Do NOT hold onto the antenna when the radio is powered on! 
3.1.1  Antenna Care and Replacement 
Do not use the portable radio with a damaged or missing antenna. A minor burn 
may result if a damaged antenna comes into contact with the skin. Replace a 
damaged antenna immediately. Operating a portable radio with the antenna missing 
could cause personal injury, damage the radio, and may violate FCC regulations. 
Use only the supplied or approved antenna. Unauthorized antennas, modifications, 
or attachments could cause damage to the radio unit and may violate FCC 
regulations. (Refer to Table 6-1.) 
3.1.2 Electronic Devices 
CAUTION
RF energy from portable radios may affect some electronic equipment. Most modern 
electronic equipment in cars, hospitals, homes, etc. is shielded from RF energy. However, 
in areas in which you are instructed to turn off two-way radio equipment, always observe 
the rules. If in doubt, turn it off! 

MM-012099-001, Rev. B 
14 
3.1.3 Aircraft 
• Always turn off a portable radio before boarding any aircraft! 
• Use it on the ground only with crew permission. 
• DO NOT use while in-flight!! 
3.1.4  Electric Blasting Caps  
To prevent accidental detonation of electric blasting caps, DO NOT use two-way 
radios within 1000 feet of blasting operations. Always obey the "Turn Off Two-Way 
Radios" signs posted where electric blasting caps are being used. (OSHA Standard: 
1926.900) 
3.1.5  Potentially Explosive Atmospheres 
Areas with potentially explosive atmospheres are often, but not always, clearly 
marked. These may be fuelling areas, such as gas stations, fuel or chemical transfer 
or storage facilities, and areas where the air contains chemicals or particles, such as 
grain, dust, or metal powders. 
Sparks in such areas could cause an explosion or fire resulting in bodily injury or 
even death. 
Turn OFF two-way radios when in any area with a potentially explosive atmosphere. 
It is rare, but not impossible that a radio or its accessories could generate sparks. 

MM-012099-001, Rev. B

4 BATTERIES 
The P5400 series portable radios use rechargeable, recyclable Nickel Cadmium (NiCd), Nickel Metal 
Hydride (NiMH), or Lithium Ion (Li Ion) batteries. Please follow the directions below to maximize the 
useful life of each type of battery. 
Do not disassemble or modify Lithium Ion battery packs.  The Lithium Ion battery packs 
are equipped with built-in safety and protection features.  Should these features be 
disabled or tampered with in any way, the battery pack can leak acid, overheat, emit 
smoke, burst, and/or, ignite. 
If the battery is ruptured or is leaking electrolyte that results in skin or eye contact with 
the electrolyte, immediately flush the affected area with water. If the battery electrolyte 
gets in the eyes, flush with water for 15 minutes and consult a physician immediately. 
4.1  CONDITIONING BATTERY PACKS 
4.1.1  Conditioning NiMH Battery Packs 
Condition a new NiMH battery before putting into use. This also applies to rechargeable NiMH batteries 
that have been stored for long periods (weeks, months, or longer). Conditioning requires fully charging 
and fully discharging the battery three (3) times using the tri-chemistry charger.  The first time the battery 
is put into the charger, this unit will condition Nickel-based battery packs by automatically charging and 
discharging (cycling) the battery.  Refer to the appropriate charger manual for details. 
CAUTION  
Failure to properly condition NiMH battery packs before initial use will result in 
shortened performance by the battery. 
4.1.2  Conditioning NiCD Battery Packs 
A new NiCD battery does not require conditioning before use.  However, M/A-COM recommends 
periodically conditioning NiCD batteries to avoid the memory effect which results when a NiCD battery 
is repeatedly charged and not fully discharged, further resulting in a lower voltage and a lower capacity. 
Fortunately, both nominal voltage and capacity are restored through battery conditioning.   
Conditioning requires fully charging and fully discharging the battery three (3) times using the tri-
chemistry charger.  The first time the battery is put into the charger, this unit will condition Nickel-based 
battery packs by automatically charging and discharging (cycling) the battery.  Refer to the appropriate 
charger manual for details.  

MM-012099-001, Rev. B 
16 
CAUTION  
Always use M/A-COM authorized chargers and conditioners. Use of unauthorized 
chargers and conditioners may void the warranty. 
4.1.3 Additional Information 
For more information regarding the proper care of portable radio batteries or establishing a battery 
maintenance program, refer to ECR-7367 which may be ordered by calling toll free 1-800-368-3277, then 
select option 7. 
4.2  CHARGING BATTERY PACKS 
Battery chargers are available from M/A-COM with nominal charge times. Combinations include single 
and multi-position charge units.  
M/A-COM chargers are specifically designed for charging nickel-based and lithium ion battery packs. 
The chargers are chemistry-specific for the battery packs and automatically adjust the charging profiles 
accordingly.  Refer to the appropriate charger manual for specific operating instructions.  
4.2.1 Charging Guidelines 
Observe the following guidelines when charging a battery pack: 
• Avoid high temperature during charging.  
• Discontinue use if the charger is overheating. 
• Only charge M/A-COM battery packs using a charger approved for use by M/A-COM. 
• Do not leave batteries in the charger indefinitely. For best results leave the battery in the charger for 
two to six hours after the Green Ready LED comes on. Then place the battery pack into service and 
fully discharge (as indicated by the radio low battery warning) before re-charging. 
If any faults are encountered while charging the battery pack, consult the charger’s manual to determine 
the cause and possible corrective action. 
4.3  BATTERY PACK USAGE 
Both Nickel-based and Lithium ion batteries vary in capacity and life cycle. For instance, NiCd batteries 
have a longer life cycle than NiMH batteries whereas NiMH batteries have a larger capacity. However, 
both Nickel-based and Lithium ion type batteries require basic usage guidelines be followed in order to 
optimize the battery runtime or shift life. 
4.3.1 Usage Guidelines 
The following guidelines will help optimize the battery runtime or shift life: 
• Ensure Nickel-based battery packs are fully discharged (as indicated by the radio low battery 
warning) before re-charging.  Full discharge is not required for Lithium Ion battery packs. 
• Periodically condition Nickel-based battery packs.  The frequency should be determined based on 
usage patterns (refer to ECR-7367). If the battery is fully discharged (to radio Low Battery warning) 
during routine use, the frequency of conditioning may be reduced.  Lithium Ion batteries do not suffer 
from memory-effect and therefore do not require conditioning. 

MM-012099-001, Rev. B 
17 
Do not leave any M/A-COM rechargeable batteries in a charger for more than a few days.  
4.4  CHANGING THE BATTERY PACK 
4.4.1  Removing the Battery Pack 
Make sure the power to the radio is turned OFF.

5 INTRODUCTION 
The P5400 series portable radio is available in two models: the P5450 Scan model with a limited 6-button 
front-mounted keypad and the P5470 System model with a 15-button DTMF front-mounted keypad. The 
UHF P5400 portable radio delivers end-to-end encrypted digital voice and IP data communications. It is 
designed to support multiple operating modes including: 
• EDACS® (Enhanced Digital Access Communications System) or ProVoice™ Trunked mode 
• P25 Trunked Mode 
• P25 Digital Conventional Mode 
• Conventional Analog mode 
The P5400 portables can include all of these modes or just one. Additional modes of operation can be 
added with software updates. 
The P5400 supports a full range of advanced digital trunking features, including voice group calls, 
priority scanning, emergency calls, late call entry, and dynamic reconfiguration. It performs autonomous 
roaming for wide area applications. High quality voice coding and robust audio components assure 
speech clarity. 
In the trunked modes, the user selects a communications “operating” system (i.e., EDACS, ProVoice, or 
P25) and group. While communicating in a trunked mode, channel selection is transparent to the user and 
is controlled via digital communication with the system controller (e.g. a CSD in an EDACS system). 
This provides advanced programmable features and fast access to communication channels. 
In Conventional Analog mode, the user selects a channel and communicates directly on that channel. A 
channel is a transmit/receive radio frequency pair. 
The exact operation of the radio will depend on the operating mode, the radio’s programming, and the 
particular radio system. Most features described in this manual can be enabled through programming. 
Consult your System Administrator for the particular features programmed into your P5400.  Then refer 
to the corresponding section(s) within this manual for feature and operation information. 
5.1 WATER RESISTANCE 
The P5400 series portable radios operate reliably even under adverse conditions. These radios meet MIL-
STD-810F specifications for wind driven rain, humidity, and salt fog.

8.1 CONTROLS 
The radio features two rotary control knobs and an emergency button mounted on the top of the radio. 
Push-To-Talk and option buttons are mounted on the side. The front mounted keypad has six buttons on 
the P5450 Scan model and 15 buttons on the P5470 System Radio. 
8.1.1  Buttons and Knobs 
This section describes the primary function of the button and knob controls (see Figure 7-2 and Figure 
7-3). Other functions associated with these controls are detailed in later sections. 
POWER ON-OFF 
VOLUME KNOB  Applies power to and adjusts the receiver’s volume.  Rotating the control 
clockwise applies power to the radio.  A single alert tone (if enabled through 
programming) indicates the radio is operational. 
Rotating the control clockwise increases the volume level.  Minimum volume 
levels may be programmed into the radio to prevent missed calls due to a low 
volume setting.  While adjusting the volume the display will momentarily 
indicate the volume level (i.e. VOL=31).  The volume range is from a minimum 
programmed level of zero (displayed as OFF in the display) up to 40, which is 
the loudest level. 
VOICE GROUP 
SELECTION 
CONTROL KNOB 
Selects systems or group/channels (depending on programming).  This is a 16-
position rotary knob.  
Note: A mechanical stop, which can limit the positions accessed, is shipped with 
the radio but must be installed. To install the mechanical stop, remove the Voice 
Group Selection control knob, loosen the set screw on the Voice Group 
Selection control knob metal base (using a 1.27 mm hex wrench), and remove 
the Voice Group Selection control knob metal base. Replace the 16 channel ring 
with the channel stop ring located at the desired channel. Reinstall the Voice 
Group Selection control knob metal base, tighten the set screw, and reinstall the 
Voice Group Selection control knob. 
EMERGENCY/ 
HOME BUTTON  Automatically selects the pre-programmed Group/System by pressing and 
holding for a programmed duration. It can also be used to declare an emergency

8.18 DIGITAL VOICE OPERATION 
Digital voice programmed systems have three (3) different voice modes: clear (analog), digital, and 
private (encrypted). The voice modes are programmed on a per-group basis within each trunked system 
and on a per-channel basis within each conventional system. 

MM-012099-001, Rev. B 
47 
8.18.1 Clear Mode 
The Clear Mode is a voice mode in which the radio transmits and receives only clear (analog) voice 
signals. These analog signals are non-digitized and non-encrypted. Clear mode transmissions can be 
monitored easily by unauthorized persons.  
Groups or channels programmed for clear operation cannot transmit or receive digital or 
private messages. 
8.18.2 Digital Mode 
The Digital Mode allows the radio to transmit and receive digitized voice signals. Digital signals provide 
improved weak signal performance and cannot be easily monitored with a standard receiver. Groups or 
channels programmed for digital operation transmit only digital signals. Message trunked group calls and 
individual phone calls (I-Calls) are answered back in the mode in which they were received assuming the 
call or hang time is still active. Individual phone, all call, and emergency calls are transmitted clear if the 
digital mode is disabled or inoperative. 
1. If receiving an analog message trunked call, the radio responds in the analog mode during the 
hang time on the working channel. 
2. If receiving an analog I-Call, the radio responds in the analog mode during the hang time. 
3. When using the *WHC* feature to respond to an I-Call (after the hang time has expired), the call 
is transmitted in the mode defined by the system mode as programmed for the current system if 
the ID being called is not in the I-Call list. If the ID is in the I-Call list, then the call is transmitted 
as defined by the I-Call mode programmed in the list for that ID. 
The overdial DTMF tones are not available while in the Digital Mode. 
8.18.3 Private Mode 
The Private Mode allows the radio to transmit encrypted messages and receive clear or private 
transmissions. The radio transmits private if the group/channel is programmed for private operation and 
forced operation is pre-programmed. If auto-select operation is pre-programmed and the radio is in the 
Private Mode, the radio transmits in the mode of the received call if the hang time is active. If no hang 
time is active, the radio transmits private.  
Cryptographic keys are transferred to the radio using a cryptographic Keyloader.  Up to seven (7) 
different cryptographic keys, numbered 1-7, can be transferred from a Keyloader and stored in the radio.  
An individual key is automatically selected on a per-group/channel basis according to the radio 
programming.  Groups and channels within the digital system can be programmed for keys 1-7 (private). 
Up to 8 banks of 7 keys can be stored for private systems.  The bank is specified per system.  
When operating on a group or channel programmed for Private Mode, all transmissions are private 
transmissions and the radio receives clear and private signals.  The status icon   is displayed when the 
Private Mode is enabled. If the selected group or channel is programmed for auto-select capability, the 
mode may be toggled between private and clear with the   key, then following the selection mode 
rules.  Radios programmed for forced private operation do not allow a change of the transmit mode.

Figure 8-10: Group/Channel Encryption Key Display 
8.18.3.2 Key Zero 
All cryptographic keys can be zeroed (erased from radio memory) by pressing the   button and while still 
pressing this button, press and hold the OPTION button. Press both buttons for 2 seconds.  A series of 
beeps will begin at the start of the 2 second period and then switch to a solid tone after the keys have been 
zeroed.  The display will indicate KEY ZERO. 
If the cryptographic key(s) are zeroed, one or more keys must be transferred from the Keyloader into the 
radio before private communications may continue. 
8.18.4 Private Operation 
8.18.4.1 Receiving an Encrypted Call 
When receiving, the radio automatically switches between clear or private operation.  If the transmission 
being received is an encrypted transmission, it will be decrypted, the   icon will be displayed, the receiver 
will unsquelch, and the message will be heard in the speaker.  For this to occur, the selected group or 
channel must be programmed for private operation and the correct cryptographic key must be loaded into 
the radio. 
8.18.4.2 Transmitting an Encrypted Call 
1. Select the desired group or channel. 
2. Place the radio in Private Mode by pressing   key; then follow the selection mode rules. On a 
System radio, the   key can be used to toggle the Private Mode ON/OFF. When Private Mode is 
enabled, the   icon is displayed. 

MM-012099-001, Rev. B 
49 
3. If the last state of the radio was Private Mode, the Private Mode will be enabled on power up. Also, 
the Private Mode will be enabled if forced operation has been programmed in the radio.  
If a group or channel is not programmed for Private Mode operation, PVT DIS will be displayed if 
an attempt is made to enable private transmit mode. It is not possible to operate on this group/channel 
in Private Mode.  
If the radio does not have the correct encryption key loaded, NO KEY# will be displayed and the call 
will not be transmitted. 
4. Continue with standard transmission procedures. A Private Mode access tone will be heard when the 
PTT button is pressed. 
8.18.4.3 Scanned Group Calls 
Receiving a Scanned Group Call is the same as receiving a selected group call. During the scan hang 
time, if the radio was programmed for auto-select, it will transmit back in the same mode it received the 
call. For example, if a clear group is entered in the scan list, it will only receive clear calls. If the same 
group was available in private and entered in the scan list, it can receive clear and private calls, provided 
auto-select was programmed in the radio. The user can select transmitting on the scanned or selected 
group. If a group is entered in the scan list more than once and under different modes, (clear, digital, or 
private), then only the first occurrence of the group will be used.

8.19.4 Nuisance Delete  
A group can also be deleted from the scan list, if it is not the currently selected group, by pressing the   
key (P5450 model) or the   key (P5470 model) during scan operation while the radio is displaying the 
unwanted group. The group will be deleted from the system's group scan list in the same manner as if 
done using the steps above. Deletions done in this manner will not remain deleted if the radio is powered 
OFF and then powered ON. 
8.20 SCANNING TRUNKED SYSTEMS 
The radio can be programmed using Radio Personality Manager (RPM) with the following System Scan 
features. Then these features are automatically enabled when the radio is powered ON. A key or menu 
option is also defined to allow the System Scan features to be toggled during radio operation. The System 
Scan state will be maintained through system changes but will default to ON when the radio is powered 
ON. 
Enable/Disable via Menu Selection 
Press   and then use the   or  buttons to scroll through the selections until SYS SCAN is 
displayed. Then press   to toggle the System Scan state. The SYSC ON or SYSC OFF display 
message is displayed for two seconds to show the new state. 
Enable/Disable via Pre-Programmed Keypad Key 
Press the key pre-programmed to toggle System Scan and the SYSC ON or SYSC OFF display message 
is displayed for two seconds to show the new state. 
8.20.1  Wide Area System Scanning 
The P5400 series radio can be pre-programmed through RPM for Wide Area System Scan operation for 
roaming across mobile systems.  EDACS radio systems manage the radios assigned to the system via a 
control channel (CC).  Upon the loss of the currently selected system's control channel, radios can be 
programmed to automatically scan the control channels of other systems. If a new control channel is 
found, the radio will switch to the new system and sound an alert tone. 
8.20.2  Priority System Scan 
The radio can also be pre-programmed for Priority System Scan.  The priority system is the desired or 
preferred system.  While receiving the control channel of the selected system, the radio will periodically 
leave the selected system and search for the control channel of the priority system.  This is done at a pre-
programmed rate defined by the value in the Priority Scan Time control, unless the ProScan™ algorithm is 
enabled, as explained in the following sections.  This priority scan timer is reset each time the PTT button 
is pressed or when the call is received.  If the priority system control channel is found, or meets the 
predefined criteria (ProScan), the radio will automatically switch to the priority system. 
8.20.2.1 Enabling the Wide Area System Scan Function 
If the radio cannot find the control channel of the selected system and begins to wide area system scan, 
the radio will only scan for the priority system control channel if the priority system is in the wide area 
scan list. 

MM-012099-001, Rev. B 
53 
8.20.2.2 When ProScan is Enabled 
The radio monitors the priority system and will switch to the priority system if the pre-preogrammed 
criteria ProScan options are met.  If ProScan is enabled, the rate at which the radio will scan for the 
priority system is defined by the System Sample Time control, set in RPM, (refer to RPM On-Line Help).  
See Section 8.20.3 for more information on ProScan. 
8.20.3 ProScan 
The radio may be programmed for ProScan system scan operation for multi-site applications.  ProScan is 
a multi-site system scanning algorithm.  ProScan provides the radio with the ability to select a new 
system for the radio to communicate on, when the selected system drops below a predefined level.  This 
algorithm enables each radio to analyze the signal quality of its current control channel and compare it 
with the signal quality of the control channel for each site in its adjacent scan list.  The signal quality 
metric used for the ProScan algorithm is based on a combination of both Received  Signal  Strength 
Indicator (RSSI) and Control Channel Verification (CCV) measurements.  When the selected system 
degrades to a pre-programmed level, the radio will begin to look for a better control channel.  Once a 
control channel that exceeds the pre-programmed parameters is found, the radio will change to the new 
system and emit a tone (if enabled through programming).  If the control channel is completely lost, the 
radio will enter Wide Area System scanning and search the programmed adjacent systems until a suitable 
control channel is found. 
8.21 EMERGENCY OPERATION 
The radio's ability to declare an emergency, clear an emergency, remain locked on an emergency system 
and group, and the emergency audio and display freeze can each be enabled or disabled through 
programming.  When an emergency is declared scanning will stop and restarts only after the emergency 
has been cleared. 
8.21.1  Receiving an Emergency Call 
When receiving an Emergency Call on the selected group and system, an alert beep is heard and   is 
displayed. The message *RXEMER* flashes in the display on line two until the emergency condition is 
cleared. 
8.21.2  Declaring an Emergency Call 
Perform the following steps to send an emergency call to a selected system and group (or on an optionally 
pre-programmed group).  
1. Press and hold the red EMERGENCY button that is on top of the radio in front of the antenna for 
approximately one second (this time is programmable and therefore could be longer or shorter; check 
with the system administrator). The radio will transmit an emergency call request with the radio ID 
until an emergency channel assignment is received.  
2. When the working channel assignment is received, the radio sounds a single beep indicating the radio 
has auto keyed (see Table 8-4) and is ready for voice transmission. *TXEMER* flashes on line two in 
the display until the emergency is cleared.  
3. Press PTT and speak into the microphone in a normal voice.   and   momentarily turn ON.  
4. Release PTT when the transmission is complete.  
To clear the emergency first press and hold the   button. While continuing to hold the   button, press the 
EMERGENCY button. (This will work if the radio is programmed to clear emergencies.)

8.22 INDIVIDUAL CALLS 
8.22.1  Receiving and Responding to an Individual Call 
When the radio receives an individual call (a call directed only to the user's radio), it un-mutes on the 
assigned working channel and displays  . The first line on the display shows the logical ID number of the 
unit sending the message, or the associated name if the ID number is found in the individual call list. The 
radio can be programmed to ring when an individual call is received. If enabled, the ring begins five 
seconds after the caller un-keys and will continue until the PTT button, the   button or the individual call 
mode is entered. 
The volume of the ring is adjustable through the volume control levels. 
If a response is made by pressing the PTT to the call prior to the programmed call-back time-out, the call 
will automatically be directed to the originating unit. If a response is not made before the call-back time-
out, the radio will return to normal receive display, and *WHC* will appear on the first line of the LCD.  
To respond after the call-back time-out, press the   key. The radio's display will show the callers ID on 
the first line and WHCI=1 on the second line. Pressing the PTT button at this point will initiate an 
individual call back to the original caller.  
The radio stores the IDs of the last 10 callers in the Calls Received List as shown. Individual calls are 
stored in the top half of the list (1-10) and Group calls are stored in the bottom half of the list (1-10). The 
most recent call is stored in position 1, the second most recent call is stored in position 2, etc.

3. To terminate the call, momentarily press the   button. 
8.23.3  Dual-Tone Multi-Frequency: Overdial/Conventional Mode 
Once the radio has established a connection to the public telephone system, it may be necessary to “over-
dial” more digits to access banking services, answering machines, credit card calls, or other types of 
systems that require Dual-Tone Multi-Frequency (DTMF) access digits. 
Overdial operation can also be used to initiate a telephone interconnect call via DTMF signaling if a dial 
tone has already been accessed on the system. This method makes a telephone interconnect call while 
operating in the conventional mode but will also function in trunked mode if a dial tone is directly 
accessible. 
Telephone numbers and other number sequences for overdialing can be stored in the phone list when 
programming the radio. These numbers are accessed by pressing the   key, then following the selection 
mode rules. Perform the following procedures to access and dial these stored numbers. 
P5450 Model Radio

8.25 STATUS/MESSAGE OPERATION 
The Status and Message operations allow for the transmission of a pre-programmed status or a pre-
programmed message to an EDACS site.  Each Status and Message is assigned an ID then cross-
referenced with the representative status condition (“Off Duty,” for example) or a message (“Call home”).  
In addition, Status conditions can also be associated with a programmable Menu entry (required for 
second method of transmitting a Status condition (see Section 8.25.1). 
8.25.1 Status Operation 
P5470 Model Radio 
One of two methods can be used to transmit a status condition. 
METHOD 1:   1. Press the   key, then use the   or  buttons to scroll to the pre-
p
rogrammed 
status condition. STATUS and 0 through 9 pre-
p
rogrammed status selections are 
available from the menu.   
2. If STATUS is selected, you need to enter the number of the status condition you 
intend to transmit. If no status has been programmed for the selected number key, 
the radio will display NO ENTRY. A valid selection will display the status for a pre-
programmed time. 
After the time-out expires or the   key has been pressed (the   key will override the 
time-out period), the status is selected and will be transmitted to the site or stored in the 
radio memory where it can be polled by the site at a future time.  
METHOD 2:  1. Press the   key.  
2. Press the corresponding pre-programmed 0 through 9 status condition key.  If no 
status has been programmed for the selected number key, the radio will display 
NO ENTRY. A valid selection will permit the status condition to appear in the top 
line of the display and the status ID to appear in the second line of the display for a 
pre-programmed time.   
After the time-out expires or the   key has been pressed (the   key will override the 
time-out period), the status is selected and will be transmitted to the site or stored in the 
radio memory where it can be polled by the site at a future time. 
View the currently selected status after it has been transmitted by pressing the   key and then the   
key and then the   button prior to the time-out period. If the status was not sent successfully to the site, 
the text associated with the status condition will flash in the display. 
The status selection can be changed by pressing a different status key 0 through 9, or the status operation 
can be cancelled by pressing Option Button 2  .  Both operations must be carried out prior to the time-
out period.  

MM-012099-001, Rev. B

8.25.2 Message Operation 
The following method can be used to transmit a Message using the Message Operation. 
1. Press the   key. 
2. Press the corresponding pre-programmed 0 through 9 pre-programmed “message” key.  If no message 
has been programmed for the selected number key, the radio will display NO ENTRY.  A valid 
selection will permit the message to appear in the top line of the display and the message ID to appear 
in the second line of the display for a pre-programmed time.   
The message selection can be changed by pressing a different message key 0 through 9, or the message 
operation can be cancelled by pressing Option Button 2  .  Both operations must be carried out prior to 
the pre-programmed time-out period.  
8.26 DYNAMIC REGROUP OPERATION 
Dynamic Regroup Operation permits multiple talk groups (up to eight) to be added to a radio via the 
system manager. The radio must be pre-programmed to respond to regrouping. Dynamic regrouping will 
not be activated in a radio until the system manager sends an activation message. Each radio that receives 
and acknowledges the regrouping instructions is successfully regrouped.  
Pressing and holding the   button for 2.5 seconds toggles the user into and out of the dynamic regroup 
groupset. A double beep will sound for entry or exit. The display will indicate REGRP_0x where "x" is a 
digit of 1 to 8 indicating the group (when dynamic regroup has been enabled by the user). If the radio is in 
dynamic regroup and the user selects a group that has not been regrouped, the display will show NO 
ENTRY. The radio will be prevented from transmitting and receiving calls in this condition except for 
scanned groups.  
After the time-out expires or the   key has been pressed (the   key will override the time-out 
period), the status is selected and will be transmitted to the site or stored in the radio memory where it can 
be polled by the site at a future time. 
8.26.1 Emergency Operation  
If the pre-programmed groupset on the currently selected system contains an EMER/HOME group and 
the radio is in dynamic regroup, the radio will declare the emergency on the currently selected dynamic 
group. 
8.27  MACRO KEY OPERATION 
Macro key operation permits the user to accomplish a series of keystrokes with a single "macro" 
keystroke. Each Macro Key is capable of executing up to twenty (20) keystrokes, to any push button input 
(i.e., keypad keys, OPTION buttons, etc.). Each macro key can be pre-programmed to activate when 
pressed or when released.  
A macro key may also be pre-programmed to change the key stroke sequence the next time the macro key 
is activated.  
For detailed operation and assignment of macro keys, contact your communications supervisor or 
administrator.

8.28 PORTABLE DATA 
The P5400 series portable radios, when operating in the EDACS Trunked configuration, permit both 
voice and data calls to be transmitted and received. The radio can handle only one type of call at a time; 
however, either data or voice is selected transparently by the operator through normal usage of the radio. 
Data communications is not supported in conventional mode.  
The radios can be connected to a Mobile Data Terminal (MDT) or to a host computer. Any RS-232 
compatible device that supports the Radio Data Interface (RDI) protocol (Version 1.91 or greater) may be 
connected to the radio. Support for an MDT or a host computer is a programmable option per radio. 
Additionally, radios may also be programmed for data only operation (no voice calls transmitted or 
received). 
8.28.1 Displays 
The following will be displayed during the various states of data mode of operation: 
TX DATA Appears on top line of display when the radio is transmitting a data call.  
RX DATA Appears on top line of display when the radio is receiving a data call.  
DATA OFF Appears on top line of display when the radio is in the data disabled state.  
DATA ON Appears for two seconds on top line of display when the radio is toggled to the data
enabled state.  
8.28.2  DATA OFF Operation 
The radio can be placed in the data disabled state by any of the following methods. When the data state is 
disabled, DATA OFF appears on the top line of the display.  
• Declaring an emergency (not to be used unless an actual emergency condition exists). Alert tone will 
sound.  
• Pressing Option Button 1   (if pre-programmed as “no data” key). Alert tone will sound.  
• Pressing the pre-programmed “no data” (ND) key.  Refer to previous bullet. 
8.28.3  DATA ON Operation 
The data state is enabled by one of the following (depending on how it was disabled). DATA ON will 
appear on the top line in the display for two seconds then the display will return to normal.  
• Pressing the pre-programmed “no data” (ND) key toggles data state ON or OFF.  
• Clearing an emergency. This is valid only if the emergency caused “DATA OFF” operation. 
8.28.4  Exiting Data Cells 
Under normal conditions, the radio enters the scan lockout mode and returns to the control channel after 
completion of a data call (transmit or receive). If, during a data call, one of the following operations 
occurs, the data call is immediately terminated and the radio performs the desired function:  
• If the PTT is activated. 
• If an Emergency is declared by pressing the pre-programmed emergency button. 
• If a group or system is changed. 

MM-012099-001, Rev. B 
62 
8.28.5  Scan Lockout Mode 
Following the transmission or reception of a data call, if scan is enabled, scanning will stop temporarily.  
There are two independent pre-programmed times associated with this mode; one after a received data 
call and one after a transmitted data call. During this time the scan indicator will flash to indicate that scan 
is enabled but temporarily suspended. This condition typically returns to normal scan operation when the 
pre-programmed time expires; however, the following operations and conditions will terminate the scan 
lockout mode before the timeout has expired. 
• Press the   button.  
• Press the PTT.  
• Change a group or system.  
• Enter Telephone Interconnect mode.  
• Enter Individual call mode.  
• Receive a new emergency assignment.  
• Declare or clear an emergency.  
• Receive an individual or phone call.  
• Receive an Agency, Fleet, or System All Call. 
• Press   (P5450 model) or   (P5470 model) to toggle Scan ON or OFF. 
8.28.6  Data Lockout Mode 
During the voice call scan hang time (pre-programmed) the radio will not receive data calls.

9.16 HIGH/LOW POWER ADJUSTMENT 
Transmit power adjustment is possible if enabled through programming. Within conventional systems, 
transmit power is adjustable on a per channel basis. Within EDACS trunking systems, transmit power is 
adjustable on a per system basis.  
There are two ways to toggle between high and low power: 
Using the Menu Button:

9.17 DIGITAL VOICE OPERATION 
Digital voice programmed systems have three (3) different voice modes: clear (analog), digital, and 
private (encrypted). The voice modes are programmed on a per-group basis within each trunked system 
and on a per-channel basis within each conventional system. 
9.17.1 Clear Mode 
The Clear Mode is a voice mode in which the radio transmits and receives only clear (analog) voice 
signals.  These analog signals are non-digitized.  Clear mode transmissions can be monitored easily by 
unauthorized persons.  
Groups or channels programmed for clear operation cannot transmit or receive digital 
messages. 

MM-012099-001, Rev. B 
79 
9.17.2 Digital Mode 
The Digital Mode allows the radio to transmit and receive digitized voice signals. Digital signals provide 
improved weak signal performance and cannot be easily monitored with a standard receiver. Groups and 
channels programmed for digital operation transmit only digital signals. Individual phone calls (I-Calls) 
are answered back in the mode in which they were received assuming the call or hang time is still active. 
Individual phone, all call, and emergency calls are transmitted clear if the digital mode is disabled or 
inoperative. 
1. If receiving an analog message trunked call, the radio responds in the analog mode during the 
hang time on the working channel. 
2. If receiving an analog I-Call, the radio responds in the analog mode during the hang time. 
3. When using the *WHC* feature to respond to an I-Call (after the hang time has expired), the call 
is transmitted in the mode defined by the system mode as programmed for the current system if 
the ID being called is not in the I-Call list. If the ID is in the I-Call list, then the call is transmitted 
as defined by the I-Call mode programmed in the list for that ID. 
The overdial DTMF tones are not available while in the Digital Mode. 
9.17.2.1 Scanned Group Calls 
Receiving a Scanned Group Call is the same as receiving a selected group call.  During the scan hang 
time, if the radio was programmed for auto-select, it will transmit back in the same mode it received the 
call.  For example, if a clear group is entered in the scan list, it will only receive clear calls. If the same 
group was available in digital and entered in the scan list, it can receive clear and digital calls, provided 
auto-select was programmed in the radio.  The user can choose to transmit on the scanned or selected 
group.  If a group is entered in the scan list more than once under different modes (clear and digital), only 
the first occurrence of the group will be used.

10.1.1  Buttons and Knobs 
This section describes the primary function of the button and knob controls.  Refer to Figure 10-1 and 
Figure 10-2. 
POWER ON-OFF 
VOLUME KNOB  Applies power to and adjusts the receiver’s volume.  Rotating the control 
clockwise applies power to the radio.  A single alert tone (if enabled through 
programming) indicates the radio is operational. 
Rotating the control clockwise increases the volume level.  Minimum volume 
levels may be programmed into the radio to prevent missed calls due to a low 
volume setting.  While adjusting the volume the display will momentarily 
indicate the volume level (i.e. VOL=31).  The volume range is from a minimum 
programmed level of zero (displayed as OFF in the display) up to 40, which is 
the loudest level. 
VOICE GROUP 
SELECTION 
CONTROL KNOB 
Selects systems or groups/channels (depending on programming).  This is a 16-
position rotary knob.  
Note: A mechanical stop, which can limit the positions accessed, is shipped with 
the radio but must be installed.  To install the mechanical stop, remove the Voice 
Group Selection control knob, loosen the set screw on the Voice Group 
Selection control knob metal base (using a 1.27 mm hex wrench), and remove 
the Voice Group Selection control knob metal base.  Replace the 16 channel ring 
with the channel stop ring located at the desired channel.  Reinstall the Voice 
Group Selection control knob metal base, tighten the set screw, and reinstall the 
Voice Group Selection control knob.

10.16 DIGITAL VOICE OPERATION 
Digital voice programmed systems have three (3) different voice modes: clear (analog), digital, and 
private (encrypted). The voice modes are programmed on a per-group basis within each trunked system 
and on a per-channel basis within each conventional system. 
10.16.1 Clear Mode 
The Clear Mode is a voice mode in which the radio transmits and receives only clear (analog) voice 
signals.  These analog signals are non-digitized and non-encrypted.  Clear mode transmissions can be 
monitored easily by unauthorized persons.  
Groups or channels programmed for clear operation cannot transmit or receive digital or 
private messages. 
10.16.2 Digital Mode 
The Digital Mode allows the radio to transmit and receive digitized voice signals.  Digital signals provide 
improved weak signal performance and cannot be easily monitored with a standard receiver. Groups 
programmed for digital operation transmit only digital signals.  Message trunked group calls and 
individual phone calls (I-Calls) are answered back in the mode in which they were received assuming the 
call or hang time is still active.  Individual phone, all call, and emergency calls are transmitted clear if the 
digital mode is disabled or inoperative. 
1. If receiving an analog message trunked call, the radio responds in the analog mode during the hang 
time on the working channel. 
2. If receiving an analog I-Call, the radio responds in the analog mode during the hang time. 
3. When using the *WHC* feature to respond to an I-Call (after the hang time has expired), the call is 
transmitted in the mode defined by the system mode as programmed for the current system if the ID 
being called is not in the I-Call list.  If the ID is in the I-Call list, then the call is transmitted as defined 
by the I-Call mode programmed in the list for that ID. 
The overdial DTMF tones are not available while in the Digital Mode. 
10.16.3 Private Mode 
The Private Mode allows the radio to transmit encrypted messages and receive clear or private 
transmissions.  The radio transmits private if the group is programmed for private operation and forced 
operation is pre-programmed.  If auto-select operation is pre-programmed and the radio is in the Private 

MM-012099-001, Rev. B 
98 
Mode, the radio transmits in the mode of the received call if the hang time is active.  If no hang time is 
active, the radio transmits private.  
Cryptographic keys are transferred to the radio using a cryptographic Keyloader.  Up to seven (7) 
different cryptographic keys, numbered 1-7, can be transferred from a Keyloader and stored in the radio.  
An individual key is automatically selected on a per-group basis according to the radio programming. 
Groups and channels within the digital system can be programmed for keys 1-7 (private).  Up to 8 banks 
of 7 keys can be stored for private systems.  The bank is specified per system.  
When operating on a group programmed for Private Mode, all transmissions are private transmissions and 
the radio receives clear and private signals.  The status icon   is displayed when the Private Mode is 
enabled.  If the selected group is programmed for auto-select capability, the mode may be toggled 
between private and clear with the   key, then following the selection mode rules.  Radios programmed 
for forced private operation do not allow a change of the transmit mode. 
10.16.3.1 Displaying the Currently Used Cryptographic Key Number 
To Display the Currently Used Cryptographic Key Number for either the system encryption key (for 
special call such as individual, phone, all, agency or fleet) or the group key (for group calls), perform the 
following procedure: 
1. Press the   button. 
2. Use the   or   button to select "DISP KEY." 
3. Use the   or   button to toggle between displaying the system key (Figure 10-11) or the 
group/channel key (Figure 10-12). 
Figure 10-11: System Encryption Key Display 
Figure 10-12: Group/Channel Encryption Key Display 
10.16.3.2 Key Zero 
All cryptographic keys can be zeroed (erased from radio memory) by pressing the   button and while still 
pressing this button, press and hold the OPTION button.  Press both buttons for 2 seconds.  A series of 
beeps will begin at the start of the 2 second period and then switch to a solid tone after the keys have been 
zeroed.  The display will indicate KEY ZERO. 
If the cryptographic key(s) are zeroed, one or more keys must be transferred from the Keyloader into the 
radio before private communications may continue. 

MM-012099-001, Rev. B 
99 
10.16.4 Private Operation 
10.16.4.1 Receiving an Encrypted Call 
When receiving, the radio automatically switches between clear or private operation.  If the transmission 
being received is an encrypted transmission, it will be decrypted, the   icon is displayed, the receiver will 
unsquelch and the message will be heard in the speaker.  For this to occur, the selected group or channel 
must be programmed for private operation and the correct cryptographic key must be loaded into the 
radio. 
10.16.4.2 Transmitting an Encrypted Call 
1. Select the desired group or channel. 
2. Place the radio in Private Mode by pressing   key; then follow the selection mode rules. On a 
System radio, the   key can be used to toggle the Private Mode ON/OFF.  When Private Mode is 
enabled, the   icon is displayed. 
3. If the last state of the radio was Private Mode, the Private Mode will be enabled on power up. Also, 
the Private Mode will be enabled if forced operation has been programmed in the radio.  
If a group is not programmed for Private Mode operation, PVT DIS will be displayed if an attempt is 
made to enable private transmit mode. It is not possible to operate on this group in Private Mode.  
If the radio does not have the correct encryption key loaded, NO KEY# will be displayed and the call 
will not be transmitted. 
4. Continue with standard transmission procedures.  A Private Mode access tone will be heard when the 
PTT button is pressed. 
10.16.4.3 Scanned Group Calls 
Receiving a Scanned Group Call is the same as receiving a selected group call. During the scan hang 
time, if the radio was programmed for auto-select, it will transmit back in the same mode it received the 
call.  For example, if a clear group is entered in the scan list, it will only receive clear calls.  If the same 
group was available in private and entered in the scan list, it can receive clear and private calls, provided 
auto-select was programmed in the radio.  The user can select transmitting on the scanned or selected 
group.  If a group is entered in the scan list more than once, and in different modes (clear, digital, or 
private), only the first occurrence of the group will be used.

10.17 SCANNING TRUNKED GROUPS 
Groups that have been previously added to the scan list on a per system basis may be scanned.  Each 
system's group scan list is retained in memory when the radio is powered OFF or when the battery pack is 
removed.  
10.17.1  Turning Scan On and Off 
1. Toggle Scan operation ON by pressing   (P5450 model) or   (P5470 model).  The   icon rotates 
clockwise to indicate radio is scanning.  
2. Toggle Scan operation OFF by again pressing   (P5450 model) or   (P5470 model).  The   will 
disappear.  
• If the radio scans to a group other than the selected group then receives a call on the selected 
group, the radio will switch to the selected group. However, if the “scanned-to” group is 
programmed at a higher priority the radio will remain on the “scanned-to” group. 
• The radio will continue scanning if a new group is selected when scan is ON.  
3. Pressing the PTT button when scan is ON will cause the radio to transmit on the displayed group or to 
the currently selected group (depending on programming). 
10.17.2  Adding Groups to a Scan List

section sequence only advances the group to the next high priority level and stops at priority level 1.  
To select a lower priority level, the group must be deleted from the scan list and then added back to 
the scan list.  Each new group added to the scan list starts at the lowest priority.  If the Priority 1 and 
Priority 2 groups are already set and a new group is assigned as Priority 1 or Priority 2, the previously 
assigned group will change to non-priority scanning.  One of the following messages may be 
momentarily displayed. 
SCAN DIS The radio is not programmed to scan.  
FIXED P1 A Priority 1 group has been pre-programmed into the radio.  A new Priority 1 group

Any group that is not in a trunked system group scan list will show a "blank" for the time out period 
when it is the selected channel. 
10.17.4 Nuisance Delete  
A group can also be deleted from the scan list, if it is not the currently selected group, by pressing the   
key (P5450 model) or the   key (P5470 model) during scan operation while the radio is displaying the 
unwanted group. The group will be deleted from the system's group scan list in the same manner as if 
done using the steps above. Deletions done in this manner will not remain deleted if the radio is powered 
OFF and then powered ON. 
10.18 SCANNING TRUNKED SYSTEMS 
The radio can be programmed with the following System Scan features. These features are automatically 
enabled when the radio is powered ON. A key or menu option is also defined to allow the System Scan 
features to be toggled during radio operation. The System Scan state will be maintained through system 
changes but will default to ON when the radio is powered ON. 
Enable/Disable via Menu Selection 
Press   and then use the   or  buttons to scroll through the selections until SYS SCAN is 
displayed. Then press   to toggle the System Scan state. The SYSC ON or SYSC OFF display 
message is displayed for two seconds to show the new state. 
Enable/Disable via Pre-Programmed Keypad Key 
Press the key pre-programmed to toggle System Scan and the SYSC ON or SYSC OFF display message 
is displayed for two seconds to show the new state. 
10.18.1  Wide Area System Scanning 
The P5400 series radio can be programmed for Wide Area System Scan operation for roaming across 
mobile systems. Upon the loss of the currently selected system's control channel, radios can be 
programmed to automatically scan the control channels of other systems. If a new control channel is 
found, the radio will switch to the new system and sound an alert tone. 

MM-012099-001, Rev. B 
103 
10.18.2  Priority System Scan 
The radio can also be programmed for Priority System Scan. The priority system is the desired or 
preferred system. While receiving the control channel of the selected system, the radio will periodically 
leave the selected system and search for the control channel of the priority system. This is done at a 
programmable rate defined by the value in the Priority Scan Time control (unless the ProScan™ algorithm 
is enabled, as explained in the following sections). This priority scan timer is reset each time the PTT 
button is pressed or when the call is received. If the priority system control channel is found, (or meets the 
predefined criteria <ProScan>), the radio will automatically switch to the priority system. 
10.18.2.1 Enabling the Wide Area System Scan Function 
If the radio cannot find the control channel of the selected system and begins to wide area system scan, 
the radio will only scan for the priority system control channel if the priority system is in the wide area 
scan list. 
10.18.2.2 When ProScan is Enabled 
The radio monitors the priority system and will switch to the priority system if the criteria defined by the 
controls in the ProScan Options dialog box are met. If ProScan is enabled, the rate at which the radio will 
scan for the priority system is defined by the System Sample Time control, located in the ProScan 
Options dialog box. See Section 8.20.3 for more information on ProScan. 
10.18.3 ProScan 
The radio may be programmed for ProScan system scan operation for multi-site applications depending 
on the version of radio flash code. ProScan is an improved multi-site system scanning algorithm designed 
to replace ProSound™ scanning. ProScan provides the radio with the ability to select a new system for the 
radio to communicate on, when the selected system drops below a predefined level. This is accomplished 
by enabling each radio to analyze the signal quality of its current control channel and compares it with the 
signal quality of the control channel for each site in its adjacent scan list. (The signal quality metric used 
for the ProScan algorithm is based on a combination of both Received Signal Strength Indicator (RSSI) 
and Control Channel Verification (CCV) measurements.) When the selected system degrades to a pre-
programmed level, the radio will begin to look for a better control channel. Once a control channel that 
exceeds the pre-programmed parameters is found, the radio will change to the new system and emit a tone 
(if enabled through programming). If the control channel is completely lost, the radio will enter Wide 
Area System scanning and search the programmed adjacent systems until a suitable control channel is 
found. 
10.19 EMERGENCY OPERATION 
The radio's ability to declare an emergency, clear an emergency, remain locked on an emergency system 
and group, and the emergency audio and display freeze can each be enabled or disabled through 
programming. When an emergency is declared scanning will stop and restarts only after the emergency 
has been cleared. 
10.19.1  Receiving an Emergency Call 
When receiving an Emergency Call on the selected group and system, an alert beep is heard and   is 
displayed. The message *RXEMER* flashes in the display on line two until the emergency condition is 
cleared. 

MM-012099-001, Rev. B 
104 
10.19.2  Declaring an Emergency Call 
Perform the following steps to send an emergency call to a selected system and group (or on an optionally 
pre-programmed group).  
1. Press and hold the red EMERGENCY button that is on top of the radio in front of the antenna for 
approximately one second (this time is programmable and therefore could be longer or shorter; check 
with the system administrator). The radio will transmit an emergency call request with the radio ID 
until an emergency channel assignment is received.  
2. When the working channel assignment is received, the radio sounds a single beep indicating the radio 
has auto keyed (see Table 8-4) and is ready for voice transmission. *TXEMER* flashes on line two in 
the display until the emergency is cleared.  
3. Press PTT and speak into the microphone in a normal voice.   and   momentarily turn ON.  
4. Release PTT when the transmission is complete.  
To clear the emergency first press and hold the   button. While continuing to hold the   button, press the 
EMERGENCY button. (This will work if the radio is programmed to clear emergencies.) 
10.20 INDIVIDUAL CALLS 
10.20.1  Receiving and Responding to an Individual Call 
When the radio receives an individual call (a call directed only to the user's radio), it un-mutes on the 
assigned working channel and displays  . The first line on the display shows the logical ID number of the 
unit sending the message, or the associated name if the ID number is found in the individual call list. The 
radio can be programmed to ring when an individual call is received. If enabled, the ring begins five 
seconds after the caller un-keys and will continue until the PTT button, the   button or the individual call 
mode is entered. 
The volume of the ring is adjustable through the volume control levels. 
If a response is made by pressing the PTT to the call prior to the programmed call-back time-out, the call 
will automatically be directed to the originating unit. If a response is not made before the call-back time-
out, the radio will return to normal receive display, and *WHC* will appear on the first line of the LCD.  
To respond after the call-back time-out, press the   key. The radio's display will show the callers ID on 
the first line and WHCI=1 on the second line. Pressing the PTT button at this point will initiate an 
individual call back to the original caller.  
The radio stores the IDs of the last 10 callers in the Calls Received List as shown. Individual calls are 
stored in the top half of the list (1-10) and Group calls are stored in the bottom half of the list (1-10). The 
most recent call is stored in position 1, the second most recent call is stored in position 2, etc.

10.21.3  Dual-Tone Multi-Frequency: Overdial/Conventional Mode 
Once the radio has established a connection to the public telephone system, it may be necessary to “over-
dial” more digits to access banking services, answering machines, credit card calls, or other types of 
systems that require Dual-Tone Multi-Frequency (DTMF) access digits. 

MM-012099-001, Rev. B 
108 
Overdial operation can also be used to initiate a telephone interconnect call via DTMF signaling if a dial 
tone has already been accessed on the system. This method makes a telephone interconnect call while 
operating in the conventional mode but will also function in trunked mode if a dial tone is directly 
accessible. 
Telephone numbers and other number sequences for overdialing can be stored in the phone list when 
programming the radio. These numbers are accessed by pressing the   key, then following the selection 
mode rules. Perform the following procedures to access and dial these stored numbers. 
P5450 Model Radio 
1. Follow the procedure in Section 10.21.3 to establish a connection to the telephone system or consult 
the system administrator for the procedure to access a dial tone on the trunked or conventional

The Status and Message operations allow for the transmission of a pre-programmed status or a pre-
programmed message to an EDACS site.  Each Status and Message is assigned an ID then cross-
referenced with the representative status condition (“Off Duty,” for example) or a message (“Call home”).  
In addition, Status conditions can also be associated with a programmable Menu entry (required for 
second method of transmitting a Status condition (see Section 8.25.1). 

MM-012099-001, Rev. B 
110 
10.23.1 Status Operation 
P5470 Model Radio 
One of two methods can be used to transmit a status condition. 
METHOD 1:   1. Press the   key, then use the   or  buttons to scroll to the pre-
p
rogrammed 
status condition. STATUS and 0 through 9 pre-
p
rogrammed status selections are 
available from the menu.   
2. If STATUS is selected, you need to enter the number of the status condition you 
intend to transmit. If no status has been programmed for the selected number key, 
the radio will display NO ENTRY. A valid selection will display the status for a pre-
programmed time. 
After the time-out expires or the   key has been pressed (the   key will override the 
time-out period), the status is selected and will be transmitted to the site or stored in the 
radio memory where it can be polled by the site at a future time.  
METHOD 2:  1. Press the   key.  
2. Press the corresponding pre-programmed 0 through 9 status condition key.  If no 
status has been programmed for the selected number key, the radio will display 
NO ENTRY. A valid selection will permit the status condition to appear in the top 
line of the display and the status ID to appear in the second line of the display for a 
pre-programmed time.   
After the time-out expires or the   key has been pressed (the   key will override the 
time-out period), the status is selected and will be transmitted to the site or stored in the 
radio memory where it can be polled by the site at a future time. 
View the currently selected status after it has been transmitted by pressing the   key and then the   
key and then the   button prior to the time-out period. If the status was not sent successfully to the site, 
the text associated with the status condition will flash in the display. 
The status selection can be changed by pressing a different status key 0 through 9, or the status operation 
can be cancelled by pressing Option Button 2  .  Both operations must be carried out prior to the time-
out period.  
10.23.2 Message Operation 
The following method can be used to transmit a Message using the Message Operation. 
1. Press the   key. 
2. Press the corresponding pre-programmed 0 through 9 pre-programmed “message” key.  If no message 
has been programmed for the selected number key, the radio will display NO ENTRY. A valid 
selection will permit the message to appear in the top line of the display and the message ID to appear 
in the second line of the display for a pre-programmed time.   
The message selection can be changed by pressing a different message key 0 through 9, or the message 
operation can be cancelled by pressing Option Button 2  .  Both operations must be carried out prior to 
the pre-programmed time-out period.  

MM-012099-001, Rev. B

10.24  MACRO KEY OPERATION 
Macro key operation permits the user to accomplish a series of keystrokes with a single "macro" 
keystroke. Each Macro Key is capable of executing up to twenty (20) keystrokes, to any push button input 
(i.e., keypad keys, OPTION buttons, etc.). Each macro key can be pre-programmed to activate when 
pressed or when released.  
A macro key may also be pre-programmed to change the key stroke sequence the next time the macro key 
is activated.  
For detailed operation and assignment of macro keys, contact your communications supervisor or 
administrator. 
10.25 PORTABLE DATA 
The P5400 series portable radios, when operating in the EDACS Trunked configuration, permit both 
voice and data calls to be transmitted and received. The radio can handle only one type of call at a time; 
however, either data or voice is selected transparently by the operator through normal usage of the radio. 
Data communications is not supported in conventional mode.  
The radios can be connected to a Mobile Data Terminal (MDT) or to a host computer. Any RS-232 
compatible device that supports the Radio Data Interface (RDI) protocol (Version 1.91 or greater) may be 
connected to the radio. Support for MDTs or host computers is a programmable option per radio. 
Additionally, radios may also be programmed for data only operation (no voice calls transmitted or 
received).

2  SAFETY TRAINING INFORMATION 
The M/A-COM P5400 portable radio generates RF electromagnetic 
energy during transmit mode.  This radio is designed for and 
classified as “Occupational Use Only,” meaning it must be used 
only during the course of employment by individuals aware of the 
hazards and the ways to minimize such hazards.  This radio is NOT 
intended for use by the “General Population” in an uncontrolled 
environment. 
The P5400 portable radio has been tested and complies with the FCC RF exposure 
limits for “Occupational Use Only.”  In addition, this M/A-COM radio complies with 
the following Standards and Guidelines with regard to RF energy and electromagnetic 
energy levels and evaluation of such levels for exposure to humans: 
• FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compliance with 
FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields. 
• American National Standards Institute (C95.1 – 1992), IEEE Standard for Safety 
Levels with Respect to Human Exposure to Radio Frequency Electromagnetic 
Fields, 3 kHz to 300 GHz. 
• American National Standards Institute (C95.3 – 1992), IEEE Recommended 
Practice for the Measurement of Potentially Hazardous Electromagnetic Fields – 
RF and Microwave. 
2.1 RF EXPOSURE GUIDELINES 
CAUTION  
To ensure that exposure to RF electromagnetic energy is within the 
FCC allowable limits for occupational use, always adhere to the 
following guidelines: 
• DO NOT operate the radio without a proper antenna attached, as this may damage 
the radio and may also cause the FCC RF exposure limits to be exceeded.  A 
proper antenna is the antenna supplied with this radio by M/A-COM or an antenna 
specifically authorized by M/A-COM for use with this radio. 
• DO NOT transmit for more than 50% of total radio use time (“50% duty cycle”).  
Transmitting more than 50% of the time can cause FCC RF exposure compliance 
requirements to be exceeded.  The radio is transmitting when the “TX” indicator 
appears in the display.  The radio will transmit by pressing the “PTT” (Push-To-
Talk) button. 
• Always transmit using low power when possible.  In addition to conserving 
battery charge, low power can reduce RF exposure. 
• ALWAYS use M/A-COM authorized accessories (antennas, batteries, belt clips, 
speaker/mics, etc).  Use of unauthorized accessories may cause the FCC 
Occupational/Controlled Exposure RF compliance requirements to be exceeded. 

6 
• As noted in Table 2-1, ALWAYS keep the device and its antenna AT LEAST 1.1 
cm (0.43 inches) from the body and at least 2.5 cm (1.00 inch) from the face when 
transmitting to ensure FCC RF exposure compliance requirements are not 
exceeded.  However, to provide the best sound quality to the recipients of your 
transmission, M/A-COM recommends you hold the microphone at least 5 cm (2 
inches) from your mouth, and slightly off to one side.

of a RF exposure, and what to do to assure that this radio operates within the FCC RF 
exposure limits of this radio. 
2.2 ELECTROMAGNETIC 
INTERFERENCE/COMPATIBILITY 
During transmissions, M/A-COM radios generate RF energy that can possibly cause 
interference with other devices or systems.  To avoid such interference, turn off the 
radios in areas where signs are posted to do so.  DO NOT operate the transmitter in 
areas that are sensitive to electromagnetic radiation such as hospitals, aircraft, and 
blasting sites. 
3 OPERATING TIPS 
Antenna location and condition are important when operating a portable radio. 
Operating the radio in low lying areas or terrain, under power lines or bridges, inside of 
a vehicle or in a metal framed building can severely reduce the range of the unit. 
Mountains can also reduce the range of the unit.  
In areas where transmission or reception is poor, some improvement may be obtained 
by ensuring that the antenna is vertical. Moving a few yards in another direction or 
moving to a higher elevation may also improve communications. Vehicular operation 
can be aided with the use of an externally mounted antenna.  
Battery condition is another important factor in the trouble free operation of a portable 
radio. Always properly charge the batteries.  
3.1  EFFICIENT RADIO OPERATION 
For optimum audio clarity at the receiving radio, hold the portable radio approximately 
three inches from your mouth and speak into the microphone at a normal voice level.  
Keep the antenna in a vertical position when receiving or transmitting a message.  

7 
Do NOT hold onto the antenna when the radio is powered on. 
3.1.1  Antenna Care and Replacement 
Always keep the antenna at least 0.43 inches (1.1 cm.) away from 
the body and 1.0 inch (2.5 cm.) from the face when transmitting to 
ensure FCC RF exposure compliance requirements are not 
exceeded. 
Do not use the portable radio with a damaged or missing antenna. 
A minor burn may result if skin comes into contact with a damaged 
antenna. Replace a damaged antenna immediately. Operating a 
portable radio with the antenna missing could cause personal 
injury, damage the radio, and may violate FCC regulations. 
Use only supplied or approved antennas. Use of unauthorized 
antennas, modifications or attachments could cause damage to the 
radio unit and may violate FCC regulations. 
3.1.2 Electronic Devices 
CAUTION  
RF energy from portable radios may affect some electronic equipment. 
Most modern electronic equipment in cars, hospitals, homes, etc. are 
shielded from RF energy. However, in areas in which you are 
instructed to turn off two-way radio equipment, always observe the 
rules. If in doubt, turn it off! 
3.1.3 Aircraft 
Always turn off a portable radio before boarding any aircraft! 
• Use it on the ground only with crew permission. 
• DO NOT use while in-flight!! 
3.1.4  Electric Blasting Caps  
To prevent accidental detonation of electric blasting caps, DO NOT 
use two-way radios within 1000 feet of blasting operations. Always 
obey the "Turn Off Two-Way Radios" signs posted where electric 
blasting caps are being used. (OSHA Standard: 1926.900) 

8 
3.1.5 Potentially Explosive Atmospheres 
Areas with potentially explosive atmospheres are often, but not 
always, clearly marked. These may be fuelling areas, such as gas 
stations, fuel or chemical transfer or storage facilities, and areas 
where the air contains chemicals or particles, such as grain, dust, 
or metal powders. 
Sparks in such areas could cause an explosion or fire resulting in 
bodily injury or even death. 
Turn OFF two-way radios when in any area with a potentially 
explosive atmosphere. It is rare, but not impossible that a radio or 
its accessories could generate sparks.

4 OPTIONS AND ACCESSORIES 
A complete list of Options and Accessories approved for use with the P5400 portable 
radio can be found online in the Operator’s Manual MM-012099-001 at www.macom-
wireless.com.  Also reference the maintenance manual or M/A-COM’s Products and 
Services Catalog for all available options and accessories, including those items that do 
not adversely affect the RF energy exposure. 
Always use M/A-COM authorized accessories (antennas, batteries, 
belt clips, speaker/mics, etc). Use of unauthorized accessories may 
cause the FCC Occupational/Controlled Exposure RF compliance 
requirements to be exceeded. 
CAUTION  
Always use the correct options and accessories (battery, antenna, 
speaker/mic, etc.) for the radio. Immersion rated options must be used 
with an immersion rated radio. Intrinsically safe options must be used 
with intrinsically safe radios.

5 BATTERIES 
The P5400 series portable radios use rechargeable, recyclable Nickel Cadmium 
(NiCd), Nickel Metal Hydride (NiMH), or Lithium Ion (Li Ion) batteries. Please follow 
the directions below to maximize the useful life of each type of battery. 
Do not disassemble or modify Lithium Ion battery packs.  The 
Lithium Ion battery packs are equipped with built-in safety and 
protection features.  Should these features be disabled or tampered 
with in any way, the battery pack can leak acid, overheat, emit 
smoke, burst, and/or, ignite. 
If the battery is ruptured or is leaking electrolyte that results in 
skin or eye contact with the electrolyte, immediately flush the 
affected area with water. If the battery electrolyte gets in the eyes, 
flush with water for 15 minutes and consult a physician 
immediately. 
5.1  CONDITIONING NIMH BATTERY PACKS 
Condition a new NiMH battery before putting into use. This also applies to 
rechargeable NiMH batteries that have been stored for long periods (weeks, months, or 
longer). Conditioning requires fully charging and fully discharging the battery three (3) 
times using the tri-chemistry charger.  The first time the battery is put into the charger, 
this unit will condition Nickel-based battery packs by automatically charging and 
discharging (cycling) the battery.  Refer to the appropriate charger manual for details. 
CAUTION  
Failure to properly condition NiMH battery packs before initial use will 
result in shortened performance by the battery. 
5.2  CONDITIONING NICD BATTERY PACKS 
A new NiCD battery does not require conditioning before use.  However, M/A-COM 
recommends periodically conditioning NiCD batteries to avoid the memory effect 
which results when a NiCD battery is repeatedly charged and not fully discharged, 
further resulting in a lower voltage and a lower capacity. Fortunately, both nominal 
voltage and capacity are restored through battery conditioning.   
Conditioning requires fully charging and fully discharging the battery three (3) times 
using the tri-chemistry charger.  The first time the battery is put into the charger, this 
unit will condition Nickel-based battery packs by automatically charging and 
discharging (cycling) the battery.  Refer to the appropriate charger manual for details.  

11 
5.3  CONDITIONING LI ION BATTERY PACKS 
Lithium Ion battery packs do not suffer from memory effect and therefore do not 
require conditioning.   
CAUTION  
Always use M/A-COM authorized chargers and conditioners. Use of 
unauthorized chargers and conditioners may void the warranty.
