FCC INFORMATION
• FOR CLASS B UNINTENTIONAL RADIATORS:
This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to part 15 of
the FCC Rules. These limits are designed to provide reason-
able protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate
radio frequency energy and, if not installed and used in ac-
cordance with the instructions, may cause harmful interfer-
ence to radio communications. However, there is no guaran-
tee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
•Reorientorrelocatethereceivingantenna.
•Increasetheseparationbetweentheequipmentandre-
ceiver.
•Connecttheequipmentintoanoutletonacircuitdiffer-
ent from that to which the receiver is connected.
•Consultthedealeroranexperiencedradio/TVtechnician
for help.

thority to operate this transceiver under FCC regulations.
ii
PRECAUTIONS
RWARNING! NEVER connect the transceiver to an
AC outlet. This may pose a fire hazard or result in an electric
shock.
RWARNING! NEVER connect the transceiver to a
power source of more than 16 V DC or use reverse polarity.
This could cause a fire or damage the transceiver.
RWARNING! NEVER cut the DC power cable be-
tween the DC plug and fuse holder. If an incorrect connection
is made after cutting, the transceiver might be damaged.
RWARNING! NEVER place the transceiver where
normal operation of the vehicle may be hindered or where it
could cause bodily injury.
CAUTION: NEVER allow children to touch the trans-
ceiver.
CAUTION: NEVER expose the transceiver to rain,
snow or any liquids.
USE the specified microphone only. Other microphones
have different pin assignments and may damage the trans-
ceiver.
DO NOT use or place the transceiver in areas with tem-
peratures below –30°C (–22°F) or above +60°C (+140°F), or
in areas subject to direct sunlight, such as the dashboard.
DO NOT operate the transceiver without running the ve-
hicle’s engine. The vehicle’s battery will quickly run out when
the transceiver transmits while the vehicle’s engine is OFF.
DO NOTplacethetransceiverinexcessivelydustyenvi-
ronments.
DO NOT place the transceiver against walls. This will ob-
struct heat dissipation.
DO NOT use harsh solvents such as benzine or alcohol
when cleaning, as they will damage the transceiver sur-
faces.
BE CAREFUL! The transceiver will become hot when
operating continuously for long periods of time.

2BASIC OPERATION
■Receiving and transmitting (Continued)
DTransmitting notes
• Transmit inhibit function
The transceiver has several inhibit functions which restrict
transmission under the following conditions:
-Thechannelisinthe‘Inaudible’(mute)mode;“ ” (Audible
icon) does not appear.
- The channel is busy. However, depending on the prepro-
grammed settings, you can transmit when the call includes
an unmatching (or matching) CTCSS (DTCS), RAN code,
or Individual or Talkgroup ID.
- The selected channel is a ‘receive only’ channel.
• Time-out timer
Ifcontinuoustransmissionexceedsthepre-programmed
time-out timer limit, the transmission is cut off.
• Penalty timer
After the transmission is cut off by the time-out timer, trans-
mission is further inhibited for the pre-programmed penalty
timer period.
• PTTID call
The transceiver automatically sends the 5-tone, DTMF, BIIS
or digital ANI ID code when [PTT] is pushed (at the begin-
ningofthetransmission),and/orwhenitisreleased(atthe
end of transmission), depending on the preprogramming.
A PTTID call also be made with the MDC 1200 signaling
system.
DTX code channel selection
If the transceiver has a key assigned to [TX Code CH Select],
the dysplay can be toggled between the operating channel
number (or name) and TX code channel number (or name).

■Emergency transmission
When [Emergency] is held down for the specified time pe-
riod*, the emergency signal is transmitted on the specified
emergency channel once or repeatedly.
When no emergency channel is specified, the call is transmit-
ted on the operating channel.
The repeat emergency signal is automatically transmitted
until you turn OFF the power.
Depending on the preprogramming, receiving a matching
5-tone code cancels the transmission.
If you want to cancel the Emergency function, hold down
[Emergency] for the pre-programmed time period again be-
fore transmitting the call.
If your transceiver is programmed for Silent operation, you
can transmit emergency calls without the beep sounding and
the LCD indication change.
IMPORTANT: It is recommended to set an emergency
channel individually to provide the certain emergency call
operation.
DNOTES
Depending on the preprogramming, the following functions
are automatically activated. Ask your dealer for details.
• Auto TX function
After the emergency call transmission, audio from the micro-
phone is automatically transmitted for a specified time pe-
riod.*
•TheHM-148GorHM-152handmicrophoneisrequired.
• Auto RX function
After the emergency call transmission, the transceiver stands
by in the audible mode for the specified time period.*
* Depending on the preprogramming. Ask your dealer for de-
tails.
■Encryption function
The encryption function provides private communication be-
tween stations while operating in the digital mode.
qPush [Encryption] to turn ON the encryption function.
•“ ” (Encryption icon) appears.
wPush [Encryption] again to turn OFF the encryption func-
tion.
•“ ” disappears.

2BASIC OPERATION
■Stun function
Thedispatchercansenda2/5-tonesignalthatwillstun,kill
or revive your transceiver.
When the Stun ID is received, a beep sounds*, and the trans-
ceiver becomes unusable. Receiving a Revive command or
entering password* (p. 8) is necessary to operate the trans-
ceiver again in this case.
When the Kill ID is received, a beep sounds*, and the trans-
ceiver becomes unusable (the transceiver switches to the
cloning required condition). Cloning the transceiver is neces-
sary to operate the transceiver again in this case.
* Depending on the preprogramming. Ask your dealer for de-
tails.
See the operating guide for details of the Stun function
with the MDC and Digital system operations. Ask your
dealer for details.
■
Power OFF Emergency function
When the transceiver has a key assigned to Power OFF
Emergency, you can use the function.
