Functions and Operations

Receiving and Transmitting Signal
Press PTT key to transmit signal, icon shows up，the channel cursor turns to white，red indicator lights up.

When the radio is under receiving status, green indicator lights up, icon shows up，the channel cursor turns to white and points the receiving band, enlarge the frequency digits.
Note : The working band as below:
TX: 144-148MHz, 420-450MHz
RX: 136-174MHz, 400-520MHz ( Scanning receiver),
FM: 66-108MHz, NOAA: 162.400-162.550MHz

Keypad Operations

Short press the following keys:

• 【MENU】Key: Enter menu
• 【EXIT A/B】Key: Switch the A/B band, press manual key to exit.
• 【▲】【▼】Key: Switch the frequencies/ Channels or switch options from manual.
• 【* 】Key: In channel mode, switch the display method to frequencies or channel number.
• 【# V/M】Key: Switch the working method to channel mode or VFO mode.
• 【0-9】: In VFO mode, users can input the frequencies through keypad manually. In channel mode, users can switch to the programmed channel by inputting the number.

Long press the following keys:

• 【▲】【▼】key：Quickly switch the frequencies/ channels or switch options from menu list. In FM mode, radio will scan the FM frequencies by long pressing this key.
• 【* 】Key, lock or unlock the keypad.
• 【# V/M】Key: Switch the working mode to channel mode or VFO mode.
• 【0 FM】Key: There are two options for this key, FM radio or NOAA weather channels.
• 【1 Scan】Key: Activate or stop scanning.
• 【2 PRI】Key: Prior transmitting function
• 【3 VOX】Key: Activate or stop VOX
• 【4 PWR】Key: High/ Low power switching
• 【5 SQL】Key: Set up Squelch level.
• 【6 DW】Key: Activate or turn off dual band dual standby function.
• 【7 LED】Key: Turn on/off the backlight.
• 【8 STEP】Key: Set up step frequency

Side Key Operation
Short press side key:

• 【Side Key 1】：Turn on/off monitor function.

• 【Side Key 2】：Turn on/off local emergency alarm. When activate this function, SOS icon will show in the display screen, and radio alerts.
  Long press side key:

• 【Side Key 1】：Turn on/off FM

• 【Side Key 2】：Turn on/off the remote emergency alarm. When activate this function, SOS icon will show in the display screen, and radio alerts on the current frequency.

Channel Memory and Deletion
Enter menu and select channel storage, you will see a form like CH-XXX Y/N, Y means effective channel, N means blank channel. Press menu key to save the channel.
If user want to change the frequency, please press 【# V/M】firstly and switch to VFO mode, under this mode, users can input the frequency manually. Then enter menu and select channel storage to save the current channel. Through menu and find out the channel deletion, select the channels you want to delete and press menu key to confirm.
Frequency Scanning
Enter menu, select frequency scanning, once the main radio receives signal from other unmatched radio, the main will auto scan the frequency and privacy code from the unmatched radio. Press【PTT】to exit or press 【MENU】 to save the matched frequency and privacy code.
Note: The 23b and 24b in mute mode are non-standard privacy codes, when user activates these modes, the standard privacy code will be invalid.
Once matched the radio with non-standard privacy code, the decoded result will be 23b or 24b.

Battery Saving
There’s five level for battery saving: 1:1-1:5, please select the level according to your needed. 1:5 means the longer standby time, but it will cause more delay for the first time receiving.
FM/ NOAA function
Enter menu, in FM radio mode, there’s FM and Weather channel options.【0 FM】is a shortcut key to turn on/off this function, the following table is for NOAA weather channels:

In FM mode, the radio will dual standby for FM radio stations or main frequency. When the radio receives signal from main frequency, will auto exit FM function. In weather channel mode, the radio will auto scan the 11 NOAA channels. Once detecting the 1050Hz emergency signal from any NOAA channel, the radio will lunch alerts, and icon shows up.

Note : The NOAA function is only workable for The United States or any countries which support NOAA channels.
