SAFETY INFORMATION
The operator of any mobile radio should be aware of certain hazards
comEMER to the operation of vehicular radio transmissions. A list of
several possible hazards is given:
1. 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
2. Interference to Vehicular Electronics Systems - Electronic fuel
injection systems, electronic anti-skid braking systems, electronic
cruise control systems, etc., are typical electronic systems that may
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.
3. Dynamite Blasting Caps - Dynamite blasting caps may be caused
to explode by operating a radio within 500 feet of the blasting caps.
Always obey the "Turn Off Two-Way Radios" signs posted where
dynamite is being used.
When transporting blasting caps in your vehicle:
a. Carry the blasting caps in a closed metal box with a soft
lining.
b. Leave the radio OFF whenever the blasting caps are
being put into or removed from the vehicle.
4. Radio Frequency Energy - To prevent burns or related physical
injury from radio frequency energy, do not operate the transmitter
when anyone outside of the vehicle is within two feet of the antenna.
5. 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:
5
• The space containing the radio equipment shall be isolated by a seal
from the space containing 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.
SAFE DRIVING RECOMMENDATIONS FOR
USERS OF MOBILE RADIOS 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 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.
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 KME 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:
1. 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
6
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!
2. The use of profane or obscene language is prohibited by Federal
law.
3. 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.
4. 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.
5. 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.
6. 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.
7. No changes or adjustments shall be made to the equipment except by
an authorized or certified electronic technician.
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 years, or both.
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.
IMPORTANT
7
In areas where transmission or reception is poor, some improvement
may be obtained by insuring that the antenna is vertical. Moving a few
yards in another direction or moving to a higher elevation may also
improve communication.

Figure 2 - KME- Display
The KME- includes an eight character 14-segment display and six status
icons. The eight character first line is used to display the selected
channel, menu items and miscellaneous operating conditions. When the
radio is programmed a personality or computer file is downloaded into
the radio. The personality defines how the radio will operate and is used
to tailor the operation of the radio for each application. Since the KME
radio clearly displays alphanumeric characters, an eight character name
can be created for each of the following items:
Systems Individual Calls
Channels Group Calls
The KME- radio displays the selected channel
by displaying the selected channel name as
defined in the personality. For example, this is
what will appear in the display if the name for
channel 4 is defined in the personality as
“Police 1”.
12
STATUS INDICATORS
The status indicators or icons are located at the bottom of the display
and provide an indication of various radio operating characteristics.
The S icon is used for channels in the scan list. The S
icon turns on if the selected channel is part of the scan
list. The scan list is a group of channels the radio
continuously Monitors for activity. This list can be
modified by the radio programmer or by the radio user.
The P1 icon is used for priority 1 channels. The P1 icon
turns on when the selected channel is defined as the
priority 1 channel or when the radio receives a call on
the priority 1 channel. In scan mode, channels defined
as priority channels have precedence over non-priority
channels. If a priority 1 channel is decoded, the radio
will drop a call while on a non-priority channel or a
priority 2 channel and then switch to the priority 1
channel to receive the call. This channel will also be
scanned more often than non-priority channels and the
priority 2 channel.
The SCAN icon indicates the condition of the SCAN
mode. The SCAN button is used to toggle scan ON and
OFF. When scan is ON, the radio Monitors all the
channels in the scan list for any activity. The SCAN
icon turns on when the scan mode is enabled.
The P2 icon represents priority 2 channels. The P2 icon
turns on when the selected channel is defined as the
priority 2 channel or when the radio receives a call on
the priority 2 channel. In scan mode, channels defined
as priority channels have precedence over non-priority
channels. If a priority 2 channel is decoded, the radio
will drop a call while on a non-priority channel and then
switch to the priority 2 channel to receive the call. This
channel will also be scanned more often than other non-
priority channels, but less than the priority 1 channel.
13
The CG icon represents decode Channel Guard. When
the user selects a channel preprogrammed with decode
Channel Guard, the CG icon turns on. Channels
programmed with Channel Guard only allow the user to
hear calls carrying the equivalent Channel Guard tones
or digital codes. This reduces the amount of "channel
chatter" the user hears.
The PG icon represents selective signaling. When the
user selects a channel preprogrammed with Multi-tone
or Type 99 tone signaling, the PG icon turns on.
Selective signaling is used to initiate individual calls,
group calls, all calls, etc. When the radio is in the
Monitor mode the PG icon flashes.
TX/RX INDICATOR
This indicator is located above the EMER button. This
indicator contains a red LED and green LED. When the
radio is transmitting the red LED turns on. When the
radio is receiving a call, the green LED turns on.
14
ALERT TONES
The KME radio generates a number of unique audible alert tones or
“beeps” to indicate various operating conditions. The alert tone feature
can be enabled or disabled through PC Programming. All of the KME
alert tones are described in the following sections:
BASIC OPERATION
TURNING THE RADIO ON
Typically, mobile radio installations require the vehicle ignition switch
to be in the Accessory or Run position before the radio will power ON.
In some applications, the radio is wired directly to the battery and the
radio will power ON regardless of the setting of the vehicle ignition.
Verify with the installer, how the radio has been connected.
From the OFF position, rotate the ON/OFF Volume
knob clockwise until the knob clicks. The radio
performs a diagnostic test and then sounds three short
tones to indicate the radio has passed the diagnostic test
and is ready for operation. The display comes ON and
indicates the currently selected channel.
?
The KME mobile preserves the following data from the
previous operating state:
• Channel Number (unless preprogrammed with a power-
up channel)
• Scan ON/OFF State
• Scan List
• Radio Enable/Disable
15
SELECTING OR CHANGING CHANNELS
Rotate the Channel Selector Knob clockwise or
counterclockwise until the desired channel appears in
the display.
The Channel Knob is a continuous rotary knob that is
used to select the desired channel from a
preprogrammed list of channels. Rotate the knob
clockwise to increment to the next channel in the list.
When the end of the list is reached the radio will wrap
to beginning of the list. Rotate the knob
counterclockwise to decrement to the previous channel
in the list.

SCAN OPERATION
The KME- mobile radio can be set up to scan (Monitor) up to 16
channels on the selected system. The scanned channels may be any
frequency within the frequency band limits of the radio. If the radio
picks up activity on one of the scanned channels, the radio will switch to
the channel and allow the user to receive the call. When the call is done,
the radio automatically switches back to the knob-selected channel.
When scan is turned ON, the radio scans all the channels in the scan list.
Initially, the scan list is created when the radio is PC Programmed, but
the KME radio allows the user to modify the scan list.
The scan list can also include a priority 1 channel and a priority 2
channel. In scan mode, channels defined as priority channels have
precedence over non-priority channels. If a call on a priority 2 channel is
received, the radio will drop a call while on a non-priority channel and
switch to the priority channel to receive the call. If a call on a priority 1
channel is received, the radio will drop a call while on a non-priority
channel or a priority 2 channel and then switch to the priority 1 channel
to receive the call. Priority channels are also scanned more often than
non-priority channels.
The following sections describe how to use the scan feature on the
KME- mobile radio.

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 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 emergency signaling sequence.
Emergency signaling is programmed to transmit in one of the following
methods:
METHOD 1: Signaling 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: Signaling 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.

TYPE 99 OPERATION
Type 99 is Ericsson’s proprietary method for in-band, two-tone
sequential signaling. It is a conventional signaling protocol used to
control the muting and unmuting of a radio. This signaling is commonly
used for selective calling of individual units or groups of units in a
conventional system. Type 99 is typically used in paging operations,
where a dispatcher is able to select which radio or radios are to be
selectively called.
If Type 99 has been setup, the radio can decode individual, group and
supergroup paging calls. When the radio decodes an appropriate Type
99 decode sequence, an alert sounds, the PG icon flashes and the radio
enters the Monitor mode.
Receiving An Individual, Group or Supergroup Call
1. Turn scan OFF. The radio cannot receive selective
calls with scan ON. When scan is enabled, the radio
automatically switches to the Monitor Mode and
Type 99 decode is disabled.
2. Select the proper system and channel as described in
the Basic Operation on page 14.
3. When the radio receives a selective call:
À The green TX/RX indicator will turn ON to
indicate the radio is receiving a carrier.
À For an individual call, a single ½ second tone
will sound to indicate the call is an individual
call.
For a group call, two short tones will sound to
indicate the call is a group call.
For a supergroup call, three short tones will
sound to indicate the call is a supergroup call.
31
À The radio switches to the Monitor mode and the
PG icon flashes.
4. To respond to the call, remove the microphone from
the hookswitch. Hold the microphone approximately
2 inches from your mouth, press the PTT button on
the side of the microphone and speak in the
microphone.
5. To end the call and return to the Selective Mode,
press the EMER button. The radio will remain in the
Monitor Mode and the PG icon will continue to
flash until the user presses the EMER button.
?At this point in the menu, radios equipped with a DTMF
microphone may enter any radio ID from the DTMF keypad.
1. When the desired individual ID or name appears in
the display, press the PTT button on the side of the
microphone and speak in the microphone. The red
TX indicator should light.
2. When you have finished speaking, release the PTT
and wait for a response (if expected). If your radio is
programmed to receive an individual
acknowledgement and does not receive an
acknowledgement, the radio will display FAIL.
3. When the call is complete, press the EMER button
and the radio will return to the Selective Mode.

Transmitting A Status Message
1. Turn scan OFF. The radio cannot transmit a status
message call with scan ON. When scan is turned ON,
the encoder is disabled and the radio is in the Monitor
mode.
2. Select the desired system and channel as described in
the Basic Operation section on page 14.
3. Observe the TX/RX indicator for any activity on the
channel. Never transmit with the green RX indicator
light ON.
4. Press and hold the EMER button for at least l second to
Monitor the channel for activity. Noise will be heard if
there is no activity on the channel. This will also help in
setting the volume level to the desired level.
5. Remove the microphone from the hookswitch.
6. Press the M button. This will bring up the KME radio
main menu.
7. Press the + or - buttons until the XXXX menu item
appears.
8. Press the M button to view the submenu items.
9. Press the + or - buttons to scroll through the submenu
items.
10. When STAT appears in the display, press the M button
to view list of preprogrammed individual calls.
33
11. Press the + or - buttons to scroll through the list of
preprogrammed individual calls. For KME- radios, this
list will consist of the radio ID for each individual call
as defined in the radio personality. For KME- radios,
this list will consist of the individual name for each
individual call as defined in the radio personality.
?At this point in the menu, radios equipped with a DTMF
microphone may enter any radio ID from the DTMF keypad.
12. When the desired individual ID or name appears in
the display, press the PTT button on the side of the
microphone and speak in the microphone. The red
TX indicator should light.

Emergency Transmissions
The KME radio can be programmed and installed to send emergency
signals. To initiate an emergency call, the Option Cable (KRD 103
133/45) must be installed with a customer supplied emergency button or
switch. See the Installation Manual LZT 123 4452 for more information.
Emergency signaling is defined in the personality. The programmable
features related to emergency signaling are described below:
v The emergency can be programmed to transmit on the selected
channel, or on a pre-programmed Home/Emergency Channel.
v The emergency can be programmed with or without an
acknowledgement from the base station. If an acknowledgement is
required, the radio will display FAIL if the acknowledgement is not
received.
v The KME radio can also be programmed to send a silent emergency.
In a silent emergency, the radio transmits the emergency without any
indication of a transmission. The TX indicator does not light and all
received calls are muted until the user presses the PTT button. The
received calls are muted to keep from endangering the user that
declared the silent emergency.
To Send An Emergency
Press and hold the emergency button for at least 1 second.
Base Station Calls
In an Enhanced environment, the radio is capable of receiving several
unique calls from the base station dispatcher. These calls do not require
a response from the user. The following sections describe each type of
call.
Interrogate Radio
The interrogate feature allows the dispatch base station to validate the
participation of a radio Monitoring the system. The base station sends
out a message to a particular radio that includes the radio ID and the
interrogate message. If the radio receives a call that includes its own ID
and the interrogate message, the radio responds by transmitting its own
radio ID back to the base station. The radio receives the call and
35
responds (transmits) back to the base station without providing any
indication to the radio user.
Disable Radio
The radio disable feature allows the dispatch base station to disable any
radio Monitoring the system. The base station sends out a message to a
particular radio that includes the radio ID and disable message. If the
radio receives a call that includes its own ID and the disable message,
the radio responds by transmitting its own radio ID back to the base
station. After responding to the base station, the radio enters a disabled
or kill mode. In the disable mode, the radio will receive calls, but no
audio is heard at the speaker. The Push-To-Talk button is also disabled.
The radio is disabled for all channels in the system. The radio will only
respond to an interrogate call or radio enable call.
Enable Radio
The radio enable feature allows the dispatch base station to reactivate or
enable any radio Monitoring the system that had previously been
disabled. The base station transmits a call to a particular radio that
includes the radio ID and the enable message. If the radio receives a call
that includes the its own radio ID and the enable message, the radio
responds by transmitting its own radio ID back to the base station. After
responding to the base station, the radio exits the disabled or kill mode.
Reset Radios
The reset radio feature allows the base station to reset a particular radio
on the system to the selective state. The base station sends out a message
to a particular radio that includes the radio ID and the reset message. If
the radio receives a call that includes its own ID and the radio reset
message, the radio responds by resetting the decoder back to the
selective state. The mobile radio does not send an acknowledgement
back to the base station.
