Scan mode

Use the side button to turn on or press and hold [SCCAN] for more than 2 seconds to start frequency or channel scanning.
Before using scanning, you must first decide under what conditions you want the intercom to continue scanning after a signal is detected.
You can choose one of the following modes

1. 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.

2. 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 begin transmission.

3. SE
   Search scanning, the walkie-talkie exits scanning when detects a signal and stays at this frequency

EM function

1. Turn on FM function, the screen will display current FM frequency
2. Press to change FM frequency, or input via keypad(65-108MHz); Press # key to scan FM frequency automatically in FM mode
3. Adjust volume via Power/volume knob
4. Press FM key again to exit FM mode.
   Note: FM function need to be set in side key customized setting

Frequency scan

Scan other radio” _s CTCSS/DCS and frequency to make a contacto After defining the side key function as a frequency scan function, turnedon through the side key. This function can scan the frequency of U/V/200M/350M, and switch the frequency, it will continue to scan CTCSS/DCS. If there is no CTCSS/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 though▲ or▼ to start the next frequency scan. DTMF

NOAA Function

After defining the side key function as the weather forecast function, the function can be turned on by the side key with 10 sets of fixed frequency points built-in, which pressed key to select the frequency you want to receive
Note: NOAA weather forecast feature is only available in countries and regions that support NOAA channels
DTMF
DTMF transmitting
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 DTMF code 0-9. ABCD#, less 6 digits then press # as ending. Done editing, press PTT to transmitting DTMEF. In edit mode press to delete encode, then  press, then long press  to exit DTMF edit mode B. DTMF Decode

ANI Name Display

This function is mainly used to display the name of the current transmitter, so as to determine which machine is currently transmitting; the machine has 60 built-in groups of names to choose from, 30 groups are fixed from No. 1 to No. 30; 30 groups (31-60 groups) can be customized by the user, and the name can be set in the identity code code group of the frequency writing software. select own radio Name, menu item 32 (local name selection) to select the local name,  the local name has 1 machine to 30 machines, and 30 groups of user- defined names (set in the identity code code group settings of the writing frequency software).
