TO/CO/SE Mode
TO: Time scanning, the walkie-talkie pauses scanning when it detects a signal, and after staying stopped for about 5 seconds, the walkie-talkie will continue scanning even if the signal is still there.
CO: Carrier scanning, the two-way radio pauses scanning when a channel is detected and keeps it on the same frequency until the signal disappears. There is a 2-second delay between the disappearance of the signal and the resumption of scanning to allow time for the response to the Other function description to begin transmission. SE: Search scanning, the walkie-talkie exits scanning when it detects a signal and stays at this frequency.

FM function

Turn on FM function, the screen will display current
FM frequency
Press to change FM frequency or input via keypad(88.1-108MHz); Press # key to scan FM frequency automatically in FM mode
Adjust volume via Power/volume knob
Press the FM key again to exit FM mode

Note: FM function needs to be set inside key customized setting.

Frequency scan

Scan other radios’ CTCSS/DCS and frequency to make a contact.
After defining the side key function as a frequency scan function, turn it on through the side key. This function can scan the frequency of /V/200M/350M, and switch the frequency band to be scanned by the [P1] key. After scanning the frequency, it will continue to scan CTCSS/DCS. If there is no TCSS/DCS, the screen will display ‘NONE’ and end the scan. At this time, the scanned data can be saved to the designated channel through the key, and the frequency scan function can be launched. Or through to start the next frequency scan. DTMF

A. DTMF encode

Quick transmitting Encode: In transmitting status, press digit keys, , # to transmit DTMF encode 0-9, ABCD#. Press key to continuously encode transmitting and release to end encode transmitting. Transmitting encode after editing: In standby mode, press [#] key to enter DTMF edit menu, input 0-9,ABCD*#, if less 6 digits then press [#] as ending. Done editing, press PTT to transmit DTMF. In edit mode press to delete encode, then press to exit DTMF edit mode.
