Signaling Combination Setup
Enter No. 01 function menu, the LCD displays "SKP". This function can improve the level of
blocking irrelative signals.
SQ: You can hear the calling when receive a matching carrier.
CTC: You can hear the calling when receive a matching carrier and CTCSS/DCS signaling.
Default: SQ
» This setting is valid only when CTCSS/DCS signaling added.
HIGH/MID/LOW Power Selection
Enter No. 02 function menu , the LCD displays "POW". This function use to control transmit power
level.
HI: Transmit with high power.
MI: Transmit with middle power.
11
LO: Transmit with low power.
Default: HI.
Band-width Selection
Enter No 03 function menu , the LCD displays "BNAD".
Select suitable bandwidth in accordance with different local conditions
WIDE: band width is 25k(Wide band)
NAR: band width is 12.5k(Middle band)
Default: WIDE.
Busy Channel Lockout
Enter No 04. function menu , the LCD displays "BUSY".
BCLO is to disable transmitting while RX signal is received. Once the channel is busy and you
press [PTT], the radio will beep as warning and get back to receiving.
BU: Enable BCLO, Carrier lockout, transmitting is inhibited when current channel receives a
matching carrier; press [PTT] to emit error voice prompt and back to receiving mode.
RL: Enable BTLO, transmitting is inhibited when current channel receives a matching carrier but
dis-matching CTCSS/DCS. Press [PTT] key to emit error voice prompt and back to receiving
mode.
OFF: BCLO is disabled. It can transmit in any receiving status.
Default: OFF.
Editing Channel Name
Enter No.05 function menu , the LCD displays "NAME".

Reverse Frequency
Enter No.07 function menu , the LCD display "REV".
When turn on this function, the TX frequency turns to RX frequency & RX frequency changes to TX
frequency. The signaling will reverse if CTCSS/DCS signaling existed in this channel.
ON: Turn on reverse function
OFF: Turn off reverse function
Default: OFF.
Talk Around
Enter No.08 function menu , the LCD displays "TALK".
This function enable direct communication with other radios in case the repeater is not activated or
when out of the repeater range. The transceiver will transmit by RX frequency with its CTCSS/DCS
signaling.
ON: Turn on talk around function
OFF: Turn off talk around function
