MODELS COVERED BY THIS MANUAL
5'l 18: UHF/VHF FM Transceiver
NOTICES TO THE USER
SAFETY: lt is important that the operator is
aware of and understands hazards
common to the operation of any
transceiver.
UHF/V//F TBANSCE/VER
PRECAUTIONS
Observe the following precautions to prevent fire,
personal injury and lransceiver damage.
1. The best work way recommended is that trans-
mitting lasts one minute and receiving four
minutes. Longtime transmitting or continuous
using in high power mode will cause the back
of transceiver heat. To place this transceiver,
do not let the back touch the cover of plastic
object.
2. Do not modify this transceiver for any reason.
3. Do not expose the transceiver to long periods
of direct sunlight,nor place it close to heating
appliances.
4. Do not place the transceiver in excessively
dusty, humid, and/or wet areas, nor on unstable
surfaces.
5. lf an abnormal odor or smoke is detected
coming from the transceiver, switch OFF the
power immediately and remove the optional
battery pack from the transceiver. Contact your
dealer.
. WARNING:
parked in gasoline seruie itati6nEl-

UHF/VHF TBA.V,1CE/VEB
Carefully unpack the transceiver. We recommend
that you identify the items listed in the following
table. lf any items are missing o. n"r" 0"""
damaged, please immediately .ont".t you

1. Switching Power ON/OFF
Turn the Power switch^y'olume control clockwise
to switch the transceiver ON. Turn the Power
switchAy'olume control counterclockwise to switch
the transceiver OFF.
2. Adjusting the Volume
Rotate the Power switchA/olume control to adjust
the volume. Clockwise increases the volume and
counterclockwise decreases it.
Note:You can press IMONI] key to hear background
noise while adjusting the volumel level.
3. Selecting a Channel
Press [CH+] key to increase the channel number.
Press [CH-] key to decrease the channel number.
4. Adjusting the Squelch
The SQL function is designed to keep the speaker
quiet when the transceiver does not receive any
signal. When open the squelch,you will hear the
background noise from speaker.
The quieting electrical level you select decides the
location of the SQL ONiOFF. lf the level selected
is too high ,you will not hear the weak signal; if the
Ievel selected is too low ,the receiving signal will
appear in the background noise.

Scanning is used to monitor the signal programmed
on channels of the transceiver. The transceiver
checks each channel to find if signal appears in state
of scanning and scanning will stop on the channel on
which there is signal existing.
The transceiver will stay on this active channel until
the received signal cease. The transceiver will wait
for 5 seconds for the signal to return, otherwise
scanning resumes, except during this time it checks
and finds new signal ( for example: PTT pressing and
etc.).
Note: Scanning can be used only when at least two
channels are stored.
Press [SCAN] key to activate scan.
O Scanning begins from the current channel and
then scan upward
O Press [CH+] or [CH-] to change the scanning
order.
O The display shows'DCS'.
Press [SCAN] key or any digit key to deactivate scan.

channals within the allowable frequency range and
you can store maximum 100 channels.
Example: Assuming the transceiver is on CH-Ol and current lrequency
on CH-01 is 450.175MH2 before switched off. Now you want to set up
450.250MH2 as receiving lrequency and 450.750MH2 as transmitting
frequency on this channel.
