PREPARATION
INSTALLING THE CHANNEL STOPPER
You can set the channel stopper position for channels 2, 4, 6, 8, 10, 12, and 14.
Inserting the Channel stopper prevents unnecessarily selecting channels which
do not exist.
• Selecting a channel which does not exist causes a continuous error tone to
sound.
1 Set the Channel selector to channel 1, then pull the Channel selector knob off
the transceiver.
• If the Channel selector is not positioned at channel 1, the knob may not
install correctly and the channel may be unable to change.
2 Insert the channel stopper.
3 Set the arrow of the Channel stopper to the highest channel number for the
transceiver.
4 Reinsert the Channel selector knob.
Channel stopper Arrow
INSTALLING THE ANTENNA
Antenna Screw the antenna into the connector on the top of the
transceiver by holding the antenna at its base and turning it
clockwise until secure.
Note:
◆The antenna is neither a handle, a key ring retainer, nor a
speaker/ microphone attachment point. Using the antenna
in these ways may damage the antenna and degrade your
transceiver’s performance.

5
INSTALLING/ REMOVING THE BATTERY PACK
The battery pack is not charged at the factory; charge it before use.
CAUTION
◆Do not short the battery terminals or dispose of the battery by re.
◆Never attempt to remove the casing from the battery pack.
1Align the battery pack with the back of the
transceiver, then press the battery pack and
transceiver firmly together until the release latch on
the base of the transceiver locks.
2To remove the battery pack, lift the safety catch on
the base of the transceiver, then press the release
latch underneath the safety catch.
3While pressing the release latch, pull the battery
pack away from the transceiver.
INSTALLING THE BELT CLIP
Belt clip If necessary, attach the belt clip using the two supplied
M3 x 8 mm screws.
Note:
◆If the belt clip is not installed, its mounting location may get
hot during continuous transmission or when left sitting in a
hot environment.
CAUTION
◆Do not use glue which is designed to prevent screw loosening when installing the belt
clip, as it may cause damage to the transceiver. Acrylic ester, which is contained in
these glues, may crack the transceiver’s back panel.

6
INSTALLING THE CAP OVER THE SPEAKER/ MICROPHONE
JACKS
Install the cap over the speaker/ microphone jacks when not using an optional
speaker/ microphone or headset.
Note:
◆To keep the transceiver water resistant, you must cover the speaker/ microphone jacks
with the supplied cap.
1Place the cap over the jacks so that the locking tabs insert into the
transceiver grooves.
2While holding the cap in place, push it towards the bottom of the
transceiver until the tabs on the cap click into place.
• To remove the cap, hold the top of the cap in place with your finger while
inserting a 2 mm or smaller flat blade screwdriver under the bottom of the
cap. Slowly slide the screwdriver in until its tip touches the tab inside the
cap, then gently pry the cap up (handle of screwdriver moving away from the
transceiver) to remove the cap.

7
INSTALLING THE OPTIONAL SPEAKER/ MICROPHONE (OR
HEADSET)
Note:
◆The transceiver is not fully water resistant when using a speaker/ microphone or
headset.
1Insert the speaker/ microphone (or headset) plugs into
the speaker/ microphone jacks of the transceiver.
2Place the locking bracket over the speaker/ microphone
(or headset) plugs so that the locking tabs insert into the
transceiver grooves.
• Push down on the locking bracket to slide it into
place.
3While holding the locking bracket in place, push it
towards the bottom of the transceiver until the tabs on
the bracket click into place.
• To remove the locking bracket, push the bracket up
from the base.

TIME-OUT TIMER (TOT)
The Time-out Timer is used to prevent you from using a channel for an extended
duration. If you continuously transmit for a preset time, the transceiver will stop
transmitting and a warning tone will sound. Release the PTT switch to stop the
tone.
BATTERY SAVER
When activated by your dealer, the Battery Saver function decreases the amount
of power used after no signal is present and no operations are being performed
for 5 seconds. When a signal is received or an operation is performed, Battery
Saver turns off.
Note:
◆While the Battery Saver is operating, the LED may flash green when receiving a QT/
DQT signal which does not match the QT/DQT tone/code set up in your transceiver.
LOW BATTERY WARNING
While operating the transceiver, the Low Battery Warning sounds until the PTT
switch is released and the LED indicator blinks red when the battery needs
recharged or replaced.
BUSY CHANNEL LOCKOUT (BCL)
When activated, BCL prevents you from interfering on a channel that is already
in use. Pressing the PTT switch will cause a warning tone to sound and the
transceiver will not transmit. Release the PTT switch to stop the tone.
