2 RF ENERGY EXPOSURE INFORMATION
2.1 RF ENERGY EXPOSURE AWARENESS, CONTROL
INFORMATION, AND OPERATION INSTRUCTIONS FOR FCC
OCCUPATIONAL USE REQUIREMENTS
Before using your mobile two-way radio, read this important RF energy awareness and
control information and operational instructions to ensure compliance with the FCC‟s RF
exposure guidelines.
NOTE
This radio is intended for use in occupational/controlled conditions, where
users have full knowledge of their exposure and can exercise control over their
exposure to meet FCC limits. This radio device is NOT authorized for general
population, consumer, or any other use.
CAUTION
Changes or modifications not expressly approved by JRC could void the user's
authority to operate the equipment.
This two-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to
provide communications between two or more users over a distance. It uses RF energy or
radio waves to send and receive calls. RF energy is one form of electromagnetic energy.
Other forms include, but are not limited to, electric power, sunlight, and x-rays. RF energy,
however, should not be confused with these other forms of electromagnetic energy, which,
when used improperly, can cause biological damage. Very high levels of x-rays, for example,
can damage tissues and genetic material.
Experts in science, engineering, medicine, health, and industry work with organizations to
develop standards for exposure to RF energy. These standards provide recommended levels
of RF exposure for both workers and the general public. These recommended RF exposure
levels include substantial margins of protection. All two-way radios marketed in North
America are designed, manufactured, and tested to ensure they meet government
established RF exposure levels. In addition, manufacturers also recommend specific
operating instructions to users of two-way radios. These instructions are important because
they inform users about RF energy exposure and provide simple procedures on how to
control it. Please refer to the following websites for more information on what RF energy
exposure is and how to control your exposure to assure compliance with established RF
exposure limits.

2.1.1 Federal Communications Commission Regulations
Your JRC JHM-875S35J mobile two-way radio is designed and tested to comply with the
FCC RF energy exposure limits for mobile two-way radios before it can be marketed in the
United States. When two-way radios are used as a consequence of employment, the FCC
requires users to be fully aware of and able to control their exposure to meet occupational
requirements. Exposure awareness can be facilitated by the use of a label directing users to
specific user awareness information. Your JRC JHM-875S35J two-way radio has an RF
exposure product label. Also, your JHM-875S35J Installation and Operator‟s Manuals
include information and operating instructions required to control your RF exposure and to
satisfy compliance requirements.
2.2 COMPLIANCE WITH RF EXPOSURE STANDARDS
Your JRC JHM-875S35J mobile two-way radio is designed and tested to comply with a
number of national and international standards and guidelines (listed below) regarding
human exposure to RF electromagnetic energy. This radio complies with the IEEE and
ICNIRP exposure limits for occupational/controlled RF exposure environment at duty
factors of up to 50% talk-50% listen and is authorized by the FCC for occupational use. In
terms of measuring RF energy for compliance with the FCC exposure guidelines, your radio
antenna radiates measurable RF energy only while it is transmitting (talking), not when it
is receiving (listening) or in standby mode.
Your JRC JHM-875S35J mobile two-way radio complies with the following RF energy
exposure standards and guidelines:
United States Federal Communications Commission (FCC), Code of Federal
Regulations; 47 CFR §§ 2 sub-part J.
American National Standards Institute (ANSI)/Institute of Electrical and Electronic
Engineers (IEEE) C95.1-1992.
Institute of Electrical and Electronic Engineers (IEEE) C95.1-1999.
CAUTION
Table 2-1 lists the recommended minimum lateral distance for a controlled
environment and for unaware bystanders in an uncontrolled environment,
from transmitting types of antennas (i.e., monopoles over a ground plane, or
dipoles) at rated radio power for mobile radios installed in a vehicle.
Transmit only when unaware bystanders are at least the uncontrolled
recommended minimum lateral distance away from the transmitting
antenna.

3 OPERATION SAFETY RECOMMENDATIONS
3.1 TRANSMITTER HAZARDS
WARNING
The operator of any mobile radio should be aware of certain hazards
common to the operation of vehicular radio transmitters. A list of several
possible hazards is given:
Explosive Atmospheres – Just as it is dangerous to fuel a vehicle with the motor
running, similar hazards exist when operating a mobile radio. Be sure to turn the radio
off while fueling a vehicle. Do not carry containers of fuel in the trunk of a vehicle if the
radio is mounted in the trunk.
Areas with potentially explosive atmosphere are often, but not always, clearly marked.
Turn OFF your radio when in any area with a potentially explosive atmosphere. It is
rare, but not impossible that the radio or its accessories could generate sparks.
Interference to Vehicular Electronics Systems – Electronic fuel injection systems,
electronic anti-skid braking systems, electronic cruise control systems, etc., are typical
electronic systems that can malfunction due to the lack of protection from radio
frequency energy present when transmitting. If the vehicle contains such equipment,
consult the dealer and enlist their aid in determining the expected performance of
electronic circuits when the radio is transmitting.
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)
Liquefied Petroleum (LP) Gas Powered Vehicles – Mobile radio installations in vehicles
powered by liquefied petroleum gas with the LP gas container in the trunk or other
sealed-off space within the interior of the vehicle must conform to the National Fire
Protection Association standard NFPA 58 requiring:
The LP gas container and its fittings.
Outside filling connections shall be used for the LP gas container.
The LP gas container shall be vented to the outside of the vehicle.
H-7YCPD0002-0 EDITION 1
16
3.2 SAFE DRIVING RECOMMENDATIONS
(Recommended by AAA)
Read the literature on the safe operation of the radio.
Keep both hands on the steering wheel and the microphone in its hanger whenever the
vehicle is in motion.
Place calls only when the vehicle is stopped.
When talking from a moving vehicle is unavoidable, drive in the slower lane. Keep
conversations brief.
If a conversation requires taking notes or complex thought, stop the vehicle in a safe
place and continue the call.
Whenever using a mobile radio, exercise caution.
H-7YCPD0002-0 EDITION 1

4 OPERATING RULES AND REGULATIONS
Two-way FM radio systems must be operated in accordance with the rules and regulations
of the local, regional, or national government.
In the United States, the JHM-875S35J mobile radio must be operated in accordance with
the rules and regulations of the Federal Communications Commission (FCC). As an
operator of two-way radio equipment, you must be thoroughly familiar with the rules that
apply to your particular type of radio operation. Following these rules helps eliminate
confusion, assures the most efficient use of the existing radio channels, and results in a
smoothly functioning radio network.
When using your two-way radio, remember these rules:
It is a violation of FCC rules to interrupt any distress or emergency message. As your
radio operates in much the same way as a telephone “party line,” always listen to make
sure that the channel is clear before transmitting. Emergency calls have priority over
all other messages. If someone is sending an emergency message – such as reporting a
fire or asking for help in an accident –
KEEP OFF THE AIR!
The use of profane or obscene language is prohibited by Federal law.
It is against the law to send false call letters or false distress or emergency messages.
The FCC requires that you keep conversations brief and confine them to business. To
save time, use coded messages whenever possible.
Using your radio to send personal messages (except in an emergency) is a violation of
FCC rules. You may send only those messages that are essential for the operation of
your business.
It is against Federal law to repeat or otherwise make known anything you overhear on
your radio. Conversations between others sharing your channel must be regarded as
confidential.
The FCC requires that you identify yourself at certain specific times by means of your
call letters. Refer to the rules that apply to your particular type of operation for the
proper procedure.
No changes or adjustments shall be made to the equipment except by an authorized or
certified electronics technician.
NOTE
Under U.S. law, operation of an unlicensed radio transmitter within the
jurisdiction of the United States may be punishable by a fine of up to
$10,000, imprisonment for up to two (2) years, or both.
H-7YCPD0002-0 EDITION 1

4.1 OPERATING TIPS
The following conditions tend to reduce the effective range of two-way radios and should be
avoided whenever possible:
Operating the radio in areas of low terrain, or while under power lines or bridges.
Obstructions such as mountains and buildings.
In areas where transmission or reception is poor, some improvement can be obtained by
moving a few yards in another direction or moving to a higher elevation.

800 MHz frequency band and the 700 MHz frequency band. The JHM-875S35J is designed
to meet the critical communications demands of public service users and complies with
MIL-STD-810F specifications.
The JHM-875S35J is capable of supporting multiple operating modes, including OpenSky
digital operation, P25 digital conventional mode, and conventional analog mode.
The JHM-875S35J uses Time Division Multiple Access (TDMA) technology in the OpenSky
mode to allow multiple users to share a single RF channel. In addition, a single RF channel
can support simultaneous digital voice and data communications.
The JHM-875S35J provides integrated voice and data services. Voice operation is provided
using a microphone and speaker included in the radio installation kit. For data transfers,
the JHM-875S35J is constructed with an industry-standard RS-232 interface serial port for
connecting an optional laptop PC.
A PC, not included with the JHM-875S35J, provides network connectivity through the
standard serial (DCE-type) interface.
The JHM-875S35J has an integrated Global Positioning System (GPS) receiver. This allows
the JHM-875S35J to fully support the Automatic Vehicular Locator (AVL) for fleet
management and dispatch applications.
The OpenSky JHM-875S35J benefits from a flexible, software-based digital radio design.
Features and user profiles are software-defined and can be reprogrammed over the air. The
optional over-the-air programming feature allows communication protocols to be changed
easily and added at any time.

5.1 REMOTE CONTROL HEAD OPERATION
For remote mount installations configured with a NCE-5341 control head, all normal radio
operations and interfaces can be handled via the control head connected to the radio unit by
a single twisted-pair connection routed through a vehicle. Up to six control units may be
attached to a trunk mount radio. Each control head provides a serial access point for data
and any one (only one at a time) can be connected to a data device such as a personal
computer.
Where multiple control heads are connected or where a dash-mount radio is installed with
additional remote control heads, the following features are available from each position:
Outgoing voice calls can be initiated. Any control head can initiate a call but only one
can talk at a time. All other connected control heads will hear both sides of the
conversation.
Incoming and outgoing audio can be heard. Outgoing audio is not broadcast at the
source position.
Independent audio control is available.
Radio settings such as talk group, scan mode etc., can be controlled. Any connected
control head can override the radio settings of other connected control heads.
Comfort settings, such as volume and display brightness that are applicable to the
individual control head can be adjusted and cannot be overridden by other control heads.
An optional intercom function is available between control units. Audio will be
broadcast to ALL connected control heads.

7 OPENSKY OPERATION
7.1 NCE-5341 FRONT PANEL COMPONENTS
The front panel of the control head includes a dot matrix display, controls for menu
navigation, an emergency button, three pre-set buttons, a Power On-Off/Volume Control
knob, and a microphone connector. Table 7-1 lists all default front panel controls and their
functions.
Figure 7-1: Front Panel
The buttons on the front panel are backlit for operation in a low ambient light level such as
nighttime operation. Some buttons also flash to provide feedback of various operating
conditions.
In addition, the front panel contains a light-level sensor that samples ambient light levels
for automatic display and button backlight brightness adjustments. In other words, it
automatically brightens the display and backlights when higher external light levels exist
and it automatically dims the display and backlights during lower external light levels.

7.2 POWER UP AND VOLUME CONTROL
7.2.1 Power Up
1. Rotate the Power On-Off/Volume Control knob clockwise to power on the radio. The
display will illuminate when the radio powers up.
2. Wait for the power-up sequence to complete, which takes approximately ten (10)
seconds.
During this time, if enabled for auto registration, the radio is provisioned with a
customized user personality designed for the user‟s specific needs by the OpenSky
network administrator.
3. When provisioning is complete, the radio will display the Dwell Display.
If User Login is required, the bottom line of the Dwell Display will flash the message
“Pls Login.”
7.2.2 Volume Control
Turn the Power On-Off/Volume Control knob clockwise to increase the volume and counter-
clockwise to decrease the volume.
7.3 SELF-TEST
After power-up, the JHM-875S35J radio undergoes a multi-function automatic registration
procedure. As many as sixteen (16) possible radio profiles are downloaded to the radio from
the network in response to the User‟s ID.
7.4 LOGIN TO THE NETWORK
Login occurs either automatically (auto registration) if the radio has a valid registration or,
if enabled and authorized for encryption (Section 7.27), requires a User ID and password.
The User ID may be remembered from the previous log-in. (Refer to Section 0 for further
details regarding log-off commands.) The password will be established before the radio is
put into operation. Contact the local OpenSky network administrator for more information.
NOTE
If necessary, contact radio system administration personnel for log-in
assistance and/or radio-specific log-in instructions.
H-7YCPD0002-0 EDITION 1
26
7.5 LOG OFF THE NETWORK
Log-off is automatically performed when powering down the radio.
If a user is logged in using encryption features, it is necessary to log-off when encryption is
no longer required.
7.6 TURNING THE RADIO OFF
To turn the radio off, rotate the Power On-Off/Volume Control knob counter-clockwise. In
multiple control head installations, turning off the last powered-up control head will also
automatically turn off the radio.
Several user-selected radio settings (i.e., scan mode, pre-set buttons, and side tone levels)
are maintained for the next operational session. At the next radio power-up, maintained
settings will automatically restore, along with the network personality settings. In multiple
control head installations, settings are maintained for each control head position.
NOTE
If power is abruptly disconnected from the radio prior to executing the
correct turn-off procedure, user-selected radio settings and last-tuned
channel information will be lost. This can extend the time required for the
radio to register with the network upon the subsequent power-up.
7.7 MENU DISPLAY AND CONTROL AREA
Following power-up, the radio display shows the default talk group (Figure 7-2). Pressing
up or down with changes the display to the next available menu. In many cases, the
dwell display automatically re-appears after no menu buttons are pressed for a short period
of time (between 10 and 30 seconds). For some menus such as the GPS and User ID menus,
this does not occur until the user presses a front panel button.
When the dwell display is active, it will change dynamically to reflect the current profile,
received talk group/caller ID (when available), or channel (when enabled).
The radio‟s display is highly interactive. It responds in the top and bottom text lines as the
user presses the menu buttons ( , and MENU) to scroll through the menu loop
and the entries for each menu. Table 7-4 outlines the basic menu structure.

7.10 PERSONALITY
As illustrated in Figure 7-3, a personality defines the profiles and talk groups available to
the user. It is the structuring of a collection of profiles and privileges established by the
OpenSky network administrator to provide the user with a comprehensive set of profiles to
communicate effectively with the necessary talk groups or individuals.
Personalities are stored on the network and downloaded over-the-air to the radio. This
process is called “provisioning.” Provisioning occurs at radio power-up and at user log-in.
Each personality can contain up to sixteen (16) profiles and each profile can contain up to
sixteen talk groups.
7.10.1 Profiles
As stated above, each profile can contain up to sixteen (16) talk groups. A profile also
defines the radio‟s emergency behavior. All transmissions are made on the selected talk
group (displayed on the top line of the dwell display). The user can change the selected talk
group to any of the other talk groups within the profile.

7.10.2 Talk Groups
A talk group represents a set of users that regularly need to communicate with one another.
There can be any number of authorized users assigned to a talk group. Talk groups are
established and organized by the OpenSky network administrator. An OpenSky talk group
is similar to a channel within a conventional FM radio system.

Each profile stored in the radio can have up to sixteen (16) talk groups. One talk group
within the currently active profile is set as the “selected talk group.” For the radio user, the
selected talk group is typically the focus of most voice transmissions and receptions. There
are two ways to change the selected talk group:
First Method:
1. Use to scroll through the menu until “TalkGrpMenu” appears on the bottom line
of the display. The currently selected talk group appears in the top line of the display.
2. Use to scroll through the available list of talk groups in the active profile. This list
is determined by the OpenSky network administrator.
Second Method:
From the dwell display, use the talk group selection knob or to scroll through the
available list of talk groups in the active profile.

7.15 ADJUSTING DISPLAY AND BUTTON BACKLIGHT
BRIGHTNESS
The radio uses a light sensor on the front panel to automatically adjust display brightness
and button backlight brightness to ambient light conditions. The display and backlights
automatically brighten at higher external light levels and automatically dim at lower
external light levels. However, the “Bright Menu” gives the user some manual brightness
control as follows:
1. Using , scroll through the menu until “Bright Menu” appears.
2. Use to increase or decrease brightness. Display and button backlight brightness
will immediately dim or brighten.
7.16 STEALTH MODE
For some users, it is important to be able to turn off the radio‟s display lights, button
backlighting, volume and side tones, but not the radio traffic. For example, in covert
operations, lights and sounds could inadvertently expose an otherwise unobservable radio
user. For this purpose, the radio has a Stealth feature that disables the radio display light,
indicator light and audible side tones.
When stealth mode is on, the radio continues to scan the programmed list of talk groups
and the user can key-up on the selected talk group.
7.16.1 Enabling Stealth Mode
1. Using , scroll through the menu until “StealthMenu” appears.
2. To immediately turn stealth mode on, press (+) or (-) with .
3. To turn stealth mode off, press any button on the radio‟s front panel.
7.16.2 Disabling Stealth Mode
Pressing any radio button other than the mic‟s PTT button or the emergency button on

7.17 ADJUSTING SIDE TONE AUDIO LEVEL
The radio sounds confirming tones called “side tones” when its buttons are pressed. Most
users find this audible confirmation helpful when navigating the menus. Side tone audio
level can be adjusted or turned completely off using the “Side Menu.”
For covert operations, it may be necessary to turn off side tones. For safety‟s sake, turning
off the radio during covert operations is not recommended.
To temporarily disable the side tones that could expose the user‟s presence and position,
use the menu buttons to access the “Side Menu” and select “Off” from the menu choices.
If the radio is operating properly but side tones are not heard when the menu buttons are
pressed, the side tones are probably turned off. To turn them back on, access the “Side
Tone” menu and select a setting other than “off.”
Use the following procedure set side tone level:
1. Use to cycle through the menu until the “Side Menu” appears in the bottom line of
the display.
2. Use to change to the desired level (Off, Low, Medium, and High). To turn side
tones completely off, use the “Off” setting.
7.18 CHANGE OPERATING MODE
4. Use to cycle through the menu until the “Mode Menu” appears in the bottom line
of the display.
5. Use to choose an available mode. Press MENU and confirm (Y/N) with and
press MENU again.

7.19 RECEIVING AND TRANSMITTING VOICE CALLS
As soon as the radio completes the startup/log-on/provision/self-test sequence and registers
on the OpenSky network, voice calls from talk groups in the active profile will be audible.
7.19.1 Receiving a Voice Call
No action is required to receive a voice call. The display responds to incoming voice calls as
follows:
When the dwell display is set to received talk group and the scan mode is Normal or
Fixed:
a. If the received talk group matches the selected talk group, then the alias (if
available) or user id of the incoming caller is displayed.
b. If the received talk group does not match the selected talk group, then the received
talk group name is displayed
When the dwell display is set to received talk group and the scan mode is None:
a. If the received talk group matches the selected talk group, then the alias (if
available) or the user id of the incoming caller is displayed.
b. If the received talk group does not match the selected talk group, then None is
displayed.
When the dwell display is not set to received talk group, then there is no display
indication of an incoming call.
Refer to Section 7.23 for detailed information on talk group scanning. Refer to Section 7.27
for detailed information regarding sending and receiving encrypted calls.
7.19.2 Transmitting a Voice Call
Transmit a voice call as follows:
1. Turn the radio on.
2. If required, log-in to the network using a user ID and password (see Section 7.4).
3. Select the desired talk group for transmitting on.
4. Press and hold the Push-to-Talk (PTT) button on the hand-held microphone, pause for a
moment, and then speak normally. For maximum clarity, hold the microphone
approximately 1 ½ inches from the mouth and do not shout or whisper into it. If the call
is queued by the network, wait for the grant tone to sound before speaking.
5. Release the PTT button when finished speaking.
Refer to Section 7.27 for detailed information regarding sending and receiving encrypted
calls.
H-7YCPD0002-0 EDITION 1

7.20 ADJUSTING AUDIO TREBLE LEVEL
The tone of received signals can be adjusted using the radio‟s “Treble Menu” as follows:
1. Use to scroll through the menu until “Treble Menu” appears. The radio‟s current
treble level setting indicates in the top line of the display. There are four levels
available: low, medium, medium-high and high.
2. Use to increase or decrease.
3. Press the MENU button or wait a few seconds to return to the Dwell Display.
H-7YCPD0002-0 EDITION 1
38
7.21 INTERCOM MODE
The optional intercom mode gives users at multiple control heads connected to the same
radio the ability to communicate with each other without transmitting over-the-air. Turn
intercom mode on and off using the “INTERCOM” menu as follows:
1. Use to cycle through the available menu items until “INTERCOM” appears in the
display.
2. Use to toggle between “On” and “Off.”
When intercom mode is turned on:
Incoming voice calls will override intercom communications for the duration of the voice
call. The radio and associated control heads will remain in intercom mode and intercom
communications will resume when the voice call ends.
“TG: INTERCOM” appears in the control head‟s display when talking on the intercom.
This indicates microphone audio is not sent out on the selected talk group; rather, it
remains localized between the radio control positions (i.e., the control heads connected
to the mobile radio).
If a call exists on the currently selected talk group when a PTT button is pressed at one
of the control heads, “TG: in use” appears in the display to indicate intercom mic audio
cannot preempt the call on the talk group.
CAUTION
A user at a radio with only one control head/front panel can turn intercom
mode on. In this case, pressing the microphone‟s PTT button will not send
microphone audio anywhere.
7.22 TALK GROUP LOCK OUT
There are two ways of focusing voice communications by suppressing calls from talk groups
in the currently active profile:
1. No Scan. By turning scan off (selecting “No Scan” via the “ScnModeMenu”), only the
selected talk group is audible.
2. Lock Out. By locking out selected talk groups, the “chatter” of the locked-out talk groups
cannot be heard. This focuses the user‟s scanning resources to calls only on desired talk
groups.
Talk group lock out is a scan-related feature. With lock out, one or more talk groups in the
active profile can be temporarily disabled from being scanned. Calls are not received on
locked-out talk groups. Lock out settings are not retained between profile changes or when
the radio is power cycled.
NOTE
Lock out is a listening (receive) function and only blocks received calls on
locked out talk groups. Lock out does not affect transmit capability. The
above methods do not apply to recent emergency lock outs.
Only talk groups in the active profile can be locked out, since they are the only talk groups
whose voice calls can be heard on the radio.
H-7YCPD0002-0 EDITION 1
39
NOTE
P1 and P2 talk groups cannot be locked out.
The default emergency and emergency-capable talk groups can be locked out if they are
NOT in an emergency state. If a talk group is locked out and is subsequently changed to the
currently selected talk group, it will automatically be unlocked by the radio so the user can
hear calls on the talk group. The radio may be configured so all talk groups are
automatically locked out by default. In this case, they must be manually unlocked, if
desired.
7.22.1 Lock Out a Talk Group
1. Use to scroll through the menu until “LockOutMenu” appears in the bottom line
of the display. The name of a talk group in the currently active profile will appear in the
top line.
2. Use to scroll through the list of talk groups, if any, until the desired talk group for
lock out appears in the top line of the display.
3. Press the MENU button to lockout the displayed talk group. A less than symbol (<)
appears next to the talk group‟s name.
4. Repeat steps 2 and 3, as needed, to lockout additional talk groups.
The dwell display will re-appear a few seconds after button presses end.
While scrolling through talk groups in the active profile, the only talk groups that appear in
the “LockOutMenu” are those in the active profile.
7.22.2 Unlock a Talk Group
1. Use to scroll through the menu until “LockOutMenu” appears in the bottom line
of the display. The name of a talk group in the currently active profile will appear in the
top line.
2. Use to scroll through the list of talk groups, if any, until the talk group desired for
unlocking appears in the top line of the display. A less-than symbol (“<”) appears next to
the name of a talk group that is currently locked out.
3. Press the MENU button to unlock the talk group. The less-than symbol (“<”) next to the
name of the talk group disappears. The dwell display appears as soon as the radio
acknowledges the selection.
NOTE
Changing the active profile removes any lockouts you have made.
Turning off the radio removes any lockouts you have made.

Three scanning modes are available for the radio, but only one can be active at any time.
Changing the scanning mode changes the way the radio scans voice calls for all of profiles
in the radio personality, no matter which profile is or becomes active.
As described in Table 7-5, the choice of scanning mode changes the span of communications
with all the talk groups in the radio‟s profiles, but does not affect interaction with the talk
groups.
Table 7-5: Scan Modes
SCAN
MODE
EXPLANATION
No Scan
Eliminates distractions.
Full communications (transmit and receive) on selected talk group.
No calls received from other talk groups.
Normal
(Default)
The user can scan all talk groups in the active profile that are not locked out
as long as there is demand on the site.
Priority (P1 and P2) groups are user selectable.
Receive calls from more than one talk group, if available from the current
site.
Allows dragging of the selected talk group, P1, P2, and default emergency
talk groups to the site on which the radio is registered. (If other calls are
available at the site, they also can be heard but they will not be actively
dragged.)
The default emergency talk group, as well as any emergency-enabled talk
groups, is only dragged if it is in emergency mode.
Fixed
Functions the same as Normal Scan Mode except the priority groups are fixed
to the selected profile‟s pre-defined P1 and P2 groups (configured via the
UAS). In this mode, P1 and P2 groups CANNOT be locked out.

7.24 MAKING SELECTIVE CALLS
Selective calling is a feature that allows two radio units to obtain and utilize an
independent voice path for a private call. Radios can be configured to both initiate and
receive selective calls or to only receive selective calls.
In the OpenSky system, a source radio can be configured to initiate selective calls through a
pre-programmed list in memory. This method uses the “speed dial list” set up by the
OpenSky network administrator and provisioned as part of the registration process.
NOTE
Selective calls are terminated if an emergency is declared. The network
limits selective calls to ten (10) minutes maximum.
H-7YCPD0002-0 EDITION 1

7.25 SELECTIVE ALERT
Selective alert messaging is an OTP feature allowing one of up to eight (8) pre-programmed
text messages (refer to Section 7.25.3) to be sent from one radio to another. The user
specifies a destination radio‟s User ID, selects one of the pre-programmed text messages,
and then transmits it to the destination radio. The message delivery system adds time-of-
day information and forwards the message to the destination (receiving) radio. The sending
radio receives a brief message noting the status of the transmission. Refer to Table 7-6 for a
list of possible status messages.
The first few characters of a message are part of the message text entered when the
message is programmed. This programming is performed by the system or network
administration personnel.
Messages successfully received by the destination radio are stored until deleted or until it is
power cycled.
7.25.1 Sending Selective Alert Messages
The destination radio‟s User ID can be selected via the menu.
1. Using , scroll through the menu until “AlertDest” (Alert Destination) appears in

7.26 EMERGENCY COMMUNICATIONS
The JHM-875S35J mobile radio can transmit both emergency voice calls and emergency
alerts over the entire network. OpenSky handles emergency calls and alerts with the
highest priority.
For critical voice communications, an emergency call can be raised on the default talk group
or the currently selected talk group by “declaring” an emergency on the talk group. The
exact talk group is determined by the currently active profile. After successfully declaring
an emergency on a talk group, the declaring radio‟s microphone remains “hot” for a
predetermined amount of time. In other words, the radio transmits audio for a period of
time even when the microphone‟s PTT button is not pressed. An emergency talk group is
provided greater priority and infinite hang-time by the radio system‟s infrastructure. Hang-
time is the maximum duration of quiet time between transmissions on the talk group before
the infrastructure assets are automatically taken away. Because an emergency call is
handled on a talk group, it is received by all radios and consoles monitoring the talk group.
An emergency alert is a data message sent by the radio to the MIS console (or any console
capable of receiving it). It identifies the radio declaring the emergency, and the radio‟s
location (if the radio is equipped with a GPS receiver). Voice audio is not automatically
transmitted during the emergency if the administrator configures the radio for alert
notification only.
7.26.1 Declaring an Emergency Call or Alert
To declare an emergency call or emergency alert, press and release the orange Emergency
button. This button is located just to the right of the CLEAR button; see Figure 7-1 on page
17. The emergency is raised after the Emergency Raise Delay (default is one second).
The OpenSky network administrator determines if the Emergency button is used to
declare an emergency call or if it is used to declare an emergency alert. This is based
upon the radio‟s currently active profile.
The OpenSky network administrator also determines if the emergency is declared on
the currently selected talk group or a “default” emergency talk group. Again, this is
based upon the radio‟s currently active profile. A talk group upon which an emergency is
declared on is considered an “emergency talk group.”
Upon successful emergency declaration:
An emergency tone will sound in the radio‟s speaker/headset if the radio is not in
stealth mode.
At the declaring radio, the Emergency button flashes red if the radio is not in stealth
mode. The administrator can configure the radio to automatically transmit upon
successful emergency declaration, at which point the MENU button will flash red.
However, the MENU button flashing red is not a requirement for successful
emergency declaration.
H-7YCPD0002-0 EDITION 1
46
On the declaring radio during an emergency call declaration, the talk group that the
emergency is declared on is temporarily displayed and then the word
“EMERGENCY” flashes on the second line of the display.
For an emergency alert declaration, “EMERG ALERT” appears in the bottom line of
the display.
For an emergency call declaration, other radio users and/or dispatchers at consoles
will hear the emergency signal, a distinctive 3-tone burst. They will also hear audio
from the declaring radio‟s “hot” microphone, if any.
For an emergency alert declaration, only dispatchers at consoles will hear the
emergency signal and, if any, audio from the declaring radio‟s “hot” microphone.
For an emergency call, the declaring radio‟s microphone remains “hot” for a
predetermined amount of time. In other words, the radio transmits audio for a
period of time even when the microphone‟s PTT button is not pressed. Audio is
transmitted over the emergency talk group. When the microphone is “hot” for this
initial period (typically ten seconds), simply speak into it for voice transmission.
If an emergency declaration is not successful, the radio will periodically re-attempt until it
is successful. During this retry period, the radio will flash “EMERG PEND” on the bottom
line of the display. It will display “EMERG RETRY” for each attempt.
7.26.2 Silent Emergency
When this feature is enabled and an emergency call or alert is declared by pressing the
emergency button, the radio will not play a tone and will display an abbreviated emergency
message (default is EBA). This feature is enabled or disabled via programming or via the
menu.
NOTE
If the Silent Emergency feature is enabled or disabled via programming, the
setting will survive power cycle. Enable/Disable selection via the menu will
NOT survive power cycle and the enable/disable state will revert to the
programmed setting at power up.
7.26.3 Clearing an Emergency Call or Alert
NOTE
Check with the system administrator to ensure that the radio is programmed
to allow an emergency to be cleared.
If enabled via programming, clear an emergency by:
1. Pressing and holding the CLEAR button and simultaneously pressing the emergency
button.
2. After the Emergency Cleared Tone sounds, release both buttons.
NOTE
If the radio is in stealth mode, clearing the emergency will take the radio out of
stealth mode.
H-7YCPD0002-0 EDITION 1
47
7.26.4 Receiving an Emergency Call
Upon receiving an emergency call declared by another radio:
An emergency tone sounds in the radio‟s speaker/headset (three short high-pitched
beeps).
“EMERGENCY” flashes in the display if the radio is not in stealth mode.
On receiving radios with the emergency talk group selected, the alias of the sending
party is displayed for 5 seconds during the open-mic period, then the word “Emergency”
flashes on the second line of the display and continues until the emergency state ends.
If scan mode is set to “No Scan” and the emergency was declared on the selected talk
group, audio on the emergency talk group is heard in the speaker/headset. See page 30
for additional information on “No Scan” operation.
If scan mode is set to “No Scan” and the emergency was declared on a talk group other
than the selected talk group, the emergency talk group (identified by an “*”) must be
selected before audio on it is heard in the speaker/headset.
If scan mode is set to “Normal” and the emergency was declared on the selected talk
group, the selected/emergency talk group‟s name remains in the top line of the display.
Audio on the emergency talk group is heard in the speaker/headset.
If scan mode is set to “Normal” and the emergency was declared on a talk group other
than the selected talk group, the emergency talk group‟s name appears in the bottom
line of the display. Audio on the emergency talk group is heard in the speaker/headset.
The declaring radio's alias appears in the bottom line of the display when the
emergency talk group is selected.
An emergency call can be dismissed as described in the following section.
NOTE
A radio declaring an emergency on a talk group has a “hot” mic time period
of typically ten (10) seconds just after it declares the emergency. This time
period may be adjusted by system or network administration personnel on a
per radio basis.
7.26.5 Dismissing an Emergency Call
NOTE
An emergency is dismissed for a configurable amount of time only (default = 5
minutes).
To ignore an emergency call declared by another radio user:
1. Press until “EmgDismiss” appears in the display.
2. Press until the talk group in the emergency state appears, as indicated by an
asterisk (*) following the talk group‟s name.
3. Press the MENU button.
H-7YCPD0002-0 EDITION 1
48
NOTE
The emergency dismiss timer is cleared when the emergency is cleared.
7.27 ENCRYPTION
In the OpenSky network, both data and voice use a 128-bit or 256-bit key encryption
standard published by the Federal Information Processing Service (FIPS), called Advanced
Encryption Standard (AES). AES is approved by the U.S. Department of Commerce for
encryption of classified materials.
When encryption is enabled on the network, data is encrypted from the MDIS to the Mobile
End System (MES) (e.g., JHM-875S35J mobile radio). This form of encryption provides air-
link security.
Voice encryption is handled automatically. Automatic encryption is initiated through the
Unified Administration Server (UAS) for a specific talk group and requires nothing from
the user.
7.27.1 Automatic Encryption
For automatic encryption, a network administrator will select the talk group to be
encrypted at the interface to the UAS. Once the talk groups have been selected and
identified as secure, credentials for key generation are generated automatically by the
system and provisioned to authorized users. This process requires that authorized users
login to the network and be authenticated. Encryption keys require no manual handling
and are never sent “in the clear” over any network interface or air-link.
If a user is engaged in a call on a talk group encrypted at the network administrator level,
“Secure Call” will appear in the bottom line of the dwell display if the user is logged in to
that talk group.
If a secure call is in progress elsewhere and the user has not logged in, the bottom of the
dwell display will alternate between “No Access” and the alias of the radio that is currently
engaged in the secure call.
7.28 PRESET BUTTONS
The front panel contains three buttons labeled A, B, and C. By holding one of these buttons
down for approximately three (3) seconds, the following current information is saved to the
function of that button:
Selected talk group
Selected profile
Selected priority talk group
Lockouts
Scan mode
Intercom mode
H-7YCPD0002-0 EDITION 1

Presets are saved and restored to/from non-volatile memory. Changing the User ID (login in
as a different user) will clear the presets since they are stored on a per-user basis.
Changing control heads will not recall presets for the previous control head.
NOTE
Preset button C can be configured via programming to reboot the radio into
a particular application mode. Contact your system administrator to
determine if this feature is enabled in your radio.
7.29 DYNAMIC REGROUPING
Dynamic regrouping requires that the network administrator determine which radio users
should be formed into an impromptu talk group to respond to particular emergency
conditions.
The administrator will edit the personalities of the affected radios to include an emergency
profile and then page the affected radios to re-register with the network to receive their
edited personalities.
In response, affected radios automatically re-register to receive their edited personalities.
During re-registration, subscriber equipment will default to the emergency profile selected
by the administrator.
7.30 GPS COORDINATES
The radio‟s current latitude and longitude coordinates may be displayed using the “GPS”
menu. The following procedure assumes a GPS antenna is connected to the radio and it is
receiving adequate signals from GPS satellites:
1. Press until the “GPS” menu appears in the bottom line of the display. Current
GPS coordinate latitude and longitude data continuously scrolls in the top line of the
display in a degrees:minutes:seconds format.
2. Use to change to another menu.
NOTE
If the internal GPS receiver‟s data is expired (30 minutes or more) or
unavailable, the radio uses the serving base station‟s coordinates [GPS (Site)
is displayed]. The GPS Menu will also indicate if the data is aged (2 minutes
or more) [GPS (Aged) is displayed]

8.5 SYSTEM/GROUP/CHANNEL SELECTION
In the following description of SYSTEM/GROUP/CHANNEL SELECTION, the term group
is used for both group and channel.
The JHM-875S35J SYSTEM/GROUP/CHANNEL knob and the ramp control are
programmable for maximum flexibility. If the SYSTEM/GROUP/CHANNEL knob is
assigned to select groups, then the ramp control is assigned to select systems. If the
SYSTEM/GROUP/CHANNEL knob is assigned to select systems, then the ramp
control is assigned to select groups. System, group, and channel selection is the primary
function for these controls.
8.5.1 System Selection
Several methods, some of which depend on programming, can be used to select a new
system. These procedures are presumed to be starting from the normal receive display.
METHOD 1:
If system selection is programmed to the SYSTEM/GROUP/CHANNEL
knob, select a system by turning the SYSTEM/GROUP/CHANNEL knob to
the desired system position. The display registers the new system name on
line 1. If the wrap option is OFF and the knob is moved to a position greater
than the number of programmed systems, the highest programmed system
will remain selected.
METHOD 2:
If system selection is programmed as the primary function of the ramp
control, select a system by pressing up or down to scroll through the system
list. The display registers the new system name on line 1.
8.5.2 Group and Channel Selection
Several methods, some of which depend on programming, can be used to select a new group
or channel. These procedures assume starting from the normal receive display.
METHOD 1:
If group selection is programmed to the SYSTEM/GROUP/CHANNEL
knob, select a group by turning the SYSTEM/GROUP/CHANNEL knob to
the desired group. The display registers the new group name on line 2. If
the wrap option is OFF and the knob is moved to a position greater than
the number of programmed groups, the highest programmed group will
remain selected.
METHOD 2:
If group selection is programmed as the primary function of the
ramp control, select a group by pressing up or down, to scroll through the
group list. The display registers the new group name on line 2.
H-7YCPD0002-0 EDITION 1
59
8.6 LAST SYSTEM/GROUP/CHANNEL RECALL
This feature, enabled through programming, allows the user to recall the last selected
system/group after an emergency or home function or system/group key function. For
example, if the Home button (pre-programmed) is pressed, the radio will go to the
designated Home system/group or channel. If the Home button is pressed again, the radio
returns to the previous system/group or channel. At this time, the user can toggle between
the Home system/group or channel and the previous system/group or channel. The
operation is the same for the SG1-SG5 buttons.
8.7 DIGITAL VOICE OPERATION (PROVOICE)
8.7.1 Voice Modes
Each system (trunked or conventional) in the radio is programmed for no digital voice
operation (analog only) or digital voice format ProVoice. ProVoice programmed systems
have three (3) different voice modes: clear (analog), digital, and private. The voice modes
are programmed on a per-group basis within each trunked system and on a per-channel
basis within each conventional system. A radio must be equipped with the encrypt/decrypt
option before it will operate in private mode.
NOTE
Current ProVoice Conventional operation is for talk-around mode only.

8.7.2 Clear Modes
In Clear Mode, the radio transmits and receives only clear (analog) voice signals. These
analog signals are non-digitized and non-encrypted. Clear Mode transmissions can easily be
monitored by unauthorized persons. Groups or channels programmed for clear operation
cannot transmit or receive unencrypted digital or private messages.
H-7YCPD0002-0 EDITION 1
60
8.7.3 ProVoice Digital Mode
ProVoice digital mode allows the radio to transmit and receive digitized voice signals. These
digital signals provide improved weak signal performance and they cannot be easily
monitored with a standard receiver. Groups and channels programmed for ProVoice digital
operation transmit only digital signals. Private calls cannot be received or transmitted
when the radio is in ProVoice digital mode because the radio does not know the
cryptographic key used.
Message trunked group calls and individual calls will be answered back in the mode they
were received, assuming the call or hang time is still active. Individual, all and emergency
calls will be transmitted clear if digital mode is disabled or inoperative.
If receiving an analog message trunked call, the radio will respond in analog mode
during the hang time on the working channel.
If receiving an analog I-Call, the radio will respond in analog mode during the hang
time.
When using the "WHC" feature to respond to an I-Call (after the hang time has expired),
the call will be 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 will be transmitted as defined by the I-Call mode programmed in the
list for that ID.
ERROR Messages
If any of the following error messages are displayed, the radio was either programmed
incorrectly or needs servicing:
DSP ERR
ERR=xxxx
DSP ERR
DIGV ERR
Power Up Only
If the ProVoice circuit board is not responding, correctly, one of the following error
messages will be displayed and the radio needs servicing:
HARDWARE
ERR= 3X
3X will be a number between 30 and 38
H-7YCPD0002-0 EDITION 1
61
8.7.4 ProVoice Private Mode
ProVoice private mode allows the radio to transmit encrypted messages and receive clear or
private transmissions. The radio will transmit private if the group/channel is programmed
for private operation and forced operation is pre-programmed.
If the radio was pre-programmed for auto-select, the radio will transmit in the following
modes;
If Private mode is enabled, transmissions are always in private mode.
If Private mode is disabled and a private call is received, the Reply transmission will be
in Private mode if the transmission is made during the scan hangtime. If the reply
transmission occurs after the scan hangtime, the transmission will be in Clear mode.
When operating on a group or channel programmed for private mode, all transmissions will
be private transmissions and the radio will receive clear and private signals. If the selected
group or channel is programmed for auto-select capability, the mode can be toggled between
private and clear with the OPTION button. Radios programmed for forced private operation
do not allow a change of the transmit mode; therefore, the OPTION has no effect.
8.7.4.1 Displaying the Currently Used Cryptographic Key Number
To display the cryptographic key currently in use for either the system encryption key (for
special call such as individual, phone, all, agency or fleet) or the group/channel key (for
group or conventional calls), perform the following procedure (Not Available on
Conventional radios):
1. Press the MENU button.
2. Use to select DISP KEY. Then press the MENU button.
3. Then use to toggle between displaying the system key or the group/channel key.

8.7.4.2 Key Zero
All cryptographic keys can be zeroed (erased from radio memory) by pressing the CLEAR
and while still pressing this button, press and hold the OPTION. Press both buttons for 2
seconds. A series of warning beeps will begin at the start of this 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 Key
Loader into the radio before private communications can continue. (Refer to Key Manager
TQS3416 Administration and Software Release Notes for further information.)
8.7.5 Private Operation
8.7.5.1 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 receiver
will unsquelch and the message will be heard in the speaker. The selected group or channel
must be programmed for private operation and the correct cryptographic key must be
loaded into the radio for this to occur.
8.7.5.2 Transmitting an Encrypted Call
1. Select the desired group or channel.
2. Place the radio in private mode by pressing the OPTION.
If the last state of the radio was private mode, the private mode will be enabled on
power up. In addition, 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 is programmed for forced private transmit operation, FRCD PVT will be
displayed if an attempt is made to disable private transmit mode. It is not possible to
transmit on this group/channel in clear mode.
If the radio does not have the correct encryption key loaded, NO KEY # will be displayed
and the call will not be transmitted.
3. Continue with standard transmission procedures. A private mode access tone will be
heard when the PTT button is pressed.
H-7YCPD0002-0 EDITION 1
63
8.7.5.3 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 in different modes (clear, digital, private), only the
first occurrence of the group will be used.
8.7.6 Conventional Operation
8.7.6.1 Outside Address
The same outside address (works similar to Channel Guard operation) must be
programmed in the transmitting and receiving radios when ProVoice digital or private
operation is enabled. If address is not correct, the radios will not communicate.
8.7.6.2 Channel Guard
Channel Guard encode is transmitted on analog clear channels only. Channel Guard decode
will operate on either a clear or private channel. The exception is when G-STAR signaling is
used (see G-STAR paragraph).
8.7.6.3 G-STAR
When G-STAR is programmed on a private channel, the radio will transmit G-STAR in
clear mode and then switch to private for the voice portion of the call. If G-STAR is sent
with Channel Guard, then both are sent in clear mode and the radio switches to private
mode. Emergency G-STAR data burst is transmitted in clear mode.
8.8 MACRO KEY OPERATION
Macro key operation permits the user to accomplish a series of keystrokes with a single
"macro" keystroke. Up to ten (10) macro keys can be defined, each capable of executing up
to twenty (20) keystrokes, to any pushbutton input (i.e., keypad keys, buttons, etc.). Each
macro key can be pre-programmed to activate when pressed or when released.
A macro key can also be pre-programmed to change the keystroke sequence the next time
the macro key is activated.
For detail operation and assignment of macro keys, contact your communications
supervisor or administrator.

9.5 RECEIVING A CALL
1. Turn the radio on by rotating the POWER ON-OFF/VOLUME knob clockwise (out of
detent). A short alert signal (if enabled through programming) indicates the radio is
ready to use.
2. Adjust the POWER ON-OFF/VOLUME knob to the desired volume level.
3. Select the desired conventional system and channel. The display indicates the current
conventional system and channel names.
4. The radio is now ready to receive calls.
5. When the radio receives a call (and the correct encoding is decoded, if programmed and
enabled), it unmutes on the channel and the BSY indicator comes on.
9.6 SENDING A CALL
1. Turn ON the radio and set the POWER ON-OFF/VOLUME knob to the desired volume
level. Select the desired conventional system and channel.
2. Ensure that the channel is not busy by pressing the CLEAR button to briefly disable
any channel decoding and unmute the receiver or observe the unlit BSY indicator. If the
Channel Busy Lockout feature is programmed for the selected channel, the radio will
not transmit when the channel is busy.
3. Press and hold the PTT button. The TX indicator will turn on and a short beep sounds
(if programmed) indicating that communication can begin.
4. Hold the microphone approximately three inches from the mouth and speak in a normal
voice.
5. Release the PTT button when the transmission is complete and listen for a reply.

9.7 EMERGENCY OPERATION
If enabled, G-STAR emergency signaling can be transmitted when operating in the
conventional mode. This G-STAR signaling will transmit 5 times with a delay between each
transmission. To send an emergency call on the selected conventional system and channel
(or on an optionally pre-programmed conventional emergency system and channel), proceed
as follows:
Press and hold the red Emergency button for approximately one second (this time is
programmable and, therefore, could be longer or shorter; check with the system
administrator). The radio turns on the TX indicator and proceeds to transmit the pre-
programmed G-STAR emergency signaling sequence.
G-STAR is programmed to transmit in one of the following methods:
METHOD 1:
G-STAR is transmitted on the selected channel. If the channel is changed the
emergency signaling will continue to be transmitted on the newly selected
channel.
METHOD 2:
Same as METHOD 1 but the radio will lock on to the currently selected
channel. Any attempts to change the system or channel will be disabled.
METHOD 3:
G-STAR is transmitted on a pre-programmed conventional emergency system
and channel regardless of the selected channel. In this case the selected
channel is available for voice transmission and the radio will periodically
change to the pre-programmed emergency system and channel to send the
emergency signaling and then change back to the selected channel.
METHOD 4:
Same as METHOD 3 but the radio will lock on to the pre-programmed
emergency system and channel. Any attempts to change the system or
channel will be disabled.
The emergency state can be cleared by turning the radio OFF and then back ON.
9.7.1 Using 5-Tone Signaling to Declare an Emergency
If 5-Tone signaling is defined for emergency declaration in place of G-STAR emergency
signaling, a pre-programmed tone sequence will be transmitted instead of the G-STAR
sequence. This emergency declaration functions as the G-STAR emergency in all other
respects.
H-7YCPD0002-0 EDITION 1
75
9.7.2 Tone Encode Transmission
In conventional mode, two keys can be defined to be tone encode triggers. If either one of
the pre-programmed tone encode triggers is pressed, a pre-programmed tone sequence will
be transmitted on the current system and channel. (See Section 9.7 if the emergency key is
used.) The TX indicator will light during tone transmission and a beep will sound at the end
of the transmission. If enabled, audible side tones will be heard in the radio speaker as well.
If PTT is pre-programmed as one of the triggers, the microphone will become active for
voice communication after the tone sequence is complete.
Tone encode will be transmitted with Channel Guard if one is defined, and tones are always
transmitted in clear voice mode, even if the channel is set for digital or private (see VOICE
MODES). Digital or private voice transmission will resume normally after the tone
transmission.
9.8 SCANNING CONVENTIONAL CHANNELS
Channels, which have been previously added to the scan list on a per system basis, can be
scanned. The selected channel is scanned (if enabled through programming) whether or not
it is in the scan list. Each conventional system's channel scan list is retained in memory
when the radio is turned OFF.
The scan rate will vary depending upon the number of channels in the scan list and
whether or not the radio is programmed to scan for channels with decoding enabled. Fewer
channels will result in a faster scan rate. If programmed for dual-priority scan operation,
the priority-one, priority-two and the remaining scan list channels are scanned. Once a
signal is detected and the correct encoded squelch signal is decoded (if programmed), the
radio receives the message and displays the received scan channel. At the same time,
scanning continues on the priority-one and priority-two channels. If a priority-one or
priority-two channel carrier, regardless of encoded squelch decoding, is detected while a
non-priority channel is being received, the display name is updated and the received
channel is switched to the priority channel. Scanning of the priority-one channel will
continue if a message is being received on the priority-two channel.
While receiving a call on a non-priority or a priority two channel, the radio periodically
checks the priority one and two channels. If Scan with Channel Guard is enabled, the radio
will use Channel Guard to decide whether to unmute on a priority channel. The radio will
stop, on squelch detection, on a priority channel. In normal operation, the radio will unmute
only on detecting the correct Channel Guard; otherwise, it will remain muted until the
priority channel call and hang time have ended. An optional feature allows the radio to
continue scanning upon the detection of the wrong Channel Guard on a priority channel.
The user can then select the rate at which this channel is scanned until the call ends.

4. Press (+) again to set the channel for Priority 2 (P2) scanning and is displayed.
5. A third press of (+) sets the channel for Priority 1 (P1) scanning and is displayed on
line 1. If the P1 or P2 channels are already set and a new channel is then assigned as
the P1 or P2 channel, the previously assigned priority channel will change to non-
priority scanning. The priority setting selection sequence is set and stops at P1,
therefore the channel must be deleted from the scan list by pressing (-) before the
channel is set to a previous priority setting. Any channel that is in a system's channel
scan list will show , , or when it is the selected channel.
9.8.2 Deleting Channels From A Scan List

9.12 TYPE 99 DECODE
If the Type 99 Decode Option has been pre-programmed, individual selective calling is
possible. The radio can now decode individual, group or supergroup paging calls. Two sets
of Type 99 paging codes must be pre-programmed into the radio. When the radio decodes an
appropriate Type 99 code sequence, an alert tone and visual indicator is provided to the
user. The receiver then operates as a noise squelched unit until Type 99 is reset. Type 99
decode continues to operate during this noise squelched period. The appropriate Type 99
alert tone will sound again if it detects a valid two-tone sequence.
Type 99 operation can be reset manually or automatically (pre-programmed). Manual reset
is achieved by briefly pressing CLEAR, if programmed. Automatic reset, if enabled, occurs
after a 30 second interval following the most recent decode of a Type 99 tone sequence.
Hook switch (pre-programmed) can also enable or disable Type 99 decode. The pre-
programmed key light will blink when Type 99 is disabled by the hook switch.
Type 99 decode will continue to be active while the radio's CLEAR button is pressed. This
allows the user to monitor calls and still be alerted when a call is directed to the user.
While the user continues to press CLEAR, the user will hear both calls and all Type 99 tone
signals. If CLEAR is pressed for longer than two (2) seconds, Type 99 decode will either be
disabled or re-enabled depending upon its present state.
To check the Type 99 enable status, press the Scan Add/Delete ramp control. The
current status of Type 99 decode will be displayed for a time-out period.
If a Horn Alert Option is installed and enabled with the Type 99 Decode Option, the radio
can beep the vehicle horn when a Type 99 call is received. This option permits alerting
persons out of the vehicle when a call is received.
NOTE
Type 99 is automatically disabled when Scan is enabled.
9.12.1 Menu Selection
Press MENU and then use the ramp control to scroll through the selections until T99
ENAB is displayed. Then press MENU to toggle the Type 99 decode state. The T99 ON or
T99 OFF display message is displayed for two seconds to show the new state.
9.12.2 Pre-Programmed Keypad Key
