down V button to readjust the sound level up/
downwards as required Sound level ranges l~l$.
MON] BUTTON /Sound level checking : To check the
sound level of your previous sound setting> press this
button while the power is ON‘
While user feels his transceiver can receive a weak
transmission (Le. his partner‘s voice becomes barely
audible during communication), pressing this button
enables him to hear the weak message more loudly,
LAMP BUTTON lDisplay bat/(light
While the power is on, giving a short press to this button
lightens the display becklight to enable monitor checking
in a dark envu'onment The display light will
automatically shut off after 20 seconds to save

with that of yours. Keep your month at 342 cm from
the transceiver when talking to ensure better voice
quality. Release FIT quickly alter you finish talking to
allow your partner to reply iYour partner‘s voice is
blocked when the FIT button is being
,. pressed (retransmitted message carmot be received with
the same transceiver simultaneously transmitting a
message )
BAITERY LOW WARN WC:
Monitor Will show “Low an” as a wanting for
replacement of batteries. The small word “on MR“ will
show up each time you press this button to ensure that
your voice is being transmitted. When the batteries
become weak only the small word “ on ” shows up while
you press the FIT
The l~6 dotted lines ( “u" ) on the monitor tells you
how weak/strong your voice is being transmitted while
the FIT button is pressed (This phenomenon can be
used as a reference for your batteries condition .) When
the FIT is not pressed, the dotted lines will show up
when the transceiver detects any trace of transmission
(The stronger the transmission it detects , the more dots
appear on the monitor) \_
TROUBLE SHOOTING:
a) If you are unable to transmit even pressing the FTP;
I) check if the batteries are Weak.
2) Check if the batteries are in correct polarity
b) If you are unable to receive your partner‘s call;
I) check ifyour channel setting is ofth same With
that of your partner
2) Check if your volume level IS too low.
3)Check if the FIT button is still being pressed
4) Check if the batteries are in good condition.
5) Check if there is a serious interference.
Transmitting/receiving to/frcrn a car or heavily
enclosed surroundings can afl‘ect efl'ective
communication range.
0) lithe hansceiver makes a lot of noises ;
1) Check if the squelch setting is too low. Set it to at
least 2. Squelch setting at zero is the same condition
as the speaker volume being maximized and thus
makes loud noises.
2) Try to stay away from electronic devices like
computers to avoid interferences.
WARN INCA:
1) Take out the batteries from the battery compartment
if the transceiver 15 not to be in service for a long
period to avoid erosion of internal parts by chemical
fiom leakage
2) Only rechargeable batteries can be used With
standard changing device (not included). Nonltal
batteries are not to be used With the charging device
3)’ Any transceiver must not be used in any work place
where radio-control mining is used. Immature or
accidental detonation may occur.
4)Even though this is legalized low-power radiocornrnuv
-nication device, any changes or replacement of inner
parts may result in higher output power and/or
fiequency range and thus breach legal regulations and
become unlawful.
