hold on for 2 seconds and release, all saved channel content be deleted.
Scan
Scan Mode
Choose scan mode by editing Menu No.21 "SC-REV". Three scan mode selection (TO—Time
Scan/CO-Carrier Scan/SE-Search Scan).
• TO—Time Scan: Stop scanning when detects a signal. Stay for 5 seconds then go on
scanning, even signal exists.
• CO--Carrier Scan: Stop scanning when detects a signal until signal vanishes. Restart scanning
after signal vanishes for 5 seconds, unless new signal detected during delay time.
• SE-- Search Scan: When detect a signal, stay at this channel and quit scanning.
Channel Scan
In channel mode, long press [# SCN] key to enter channel scan. Use [
direction([ ] plus, [
release and stay for 5 seconds, it will go on scanning, press other keys except for [PTT]
[MONI] key to end scanning and return to standby channel.
Full-range Scan
In frequency mode, press [# SCN] key to enter channel scan function, current frequency within
bandwidth range, gradually increase or decrease by frequency step, use [
direction([ ] plus, [
release and stay for 5 seconds, it will go on scanning, press other keys except for [PTT] [MONI]
key to end scanning and return to standby channel.

DTMF Encode and Decode

Utilize DTMF to achieve transceiver selective call, group call function.
Manual Call:
Press [PTT] key and hold, then use keyboard to key in corresponding characters, including 0～
9,A,B,C,D,* ,#.
※Note :Press [PTT] key and hold, then press[MENU]、[ ]、[ ]、[EXIT], to key in A,B,C,D.
Automatic Code Call
We can save DTMF number (maximum 16 bits) separately into 8 automatic dial locations by
PC programming software. When need to call out, press [PF] programmable key at side, use
[ ] [ ] key to select saved DTMF number, then press [PTT] to call out.
※Notice :When making automatic code call, need to set [PF] programmable key as DTMF dial
key to achieve DTMF call.
DTMF Receive
• When local transceiver ID number received, we can hear prompt tone, and "P CALL" displayed
in the screen, means successfully call; When group call code received, we can hear prompt
tone from transceiver, and "G CALL"displayed in the screen, means successfully call. We can
press [PTT] key to response or directly listen to the other side information. If it does not receive
