FUNCTION AND OPERATION

4.1 Transmitting Signal
Press [PTT] key, the device will transmit signal at main standby channel,and the signal icon @shows up in red, and indicator light turns red.
4.2 Receiving Signal When the device receives same frequency signal with current working channel and the CTCSS matches with each other’s, the indicator light turns green, signal icon ® shows up in blue.
4.3 Working Mode Switching
Short press # button to change the working mode to VFO frequency mode or Channel MODE. When it is changed to VFO frequency mode, the icon © will show up as VHF; When it is changed to channel mode, the icon ® will show up as CHXXX.
4.4 Frequency Changing and Repeater Frequency
Setting While under VFO mode, input frequencies manually via keypads, input 6 digits, the inputting is done. After this ,the input frequencies will be set to receiving and transmitting frequencies. If need to use repeater to relay the signals, set the TX frequencies according to the repeater frequency table. Oper-ation: Under VFO mode, long press[] button, icon turns red, the input function actives, and input 6 digits, so the inputting is done automatically. The input frequencies will set to TX frequencies. At this time the screen will shift to receiving status. If need to change transmitting frequencies, long press [] button again. Short press[ ]/[ ]can switch preset working frequen- cies.Long press[ ]/[ ] is fast switching function.
4.5 Channel Switching
Under channel mode status, input channel number via keypads to switch to appointed channel.Short press [ ]/[ ]to switch to working channels one by one. Long press [A]/[V]is fast switching function.
4.6 Air Band Receiving
When the working frequency is set within the range of 108-136MHz, the icon ()shows up AM, which means the device is under air band receiving status. The device is not allowed to transmit signals under air band status.
4.7 Frequency Detecting and Decoding
Side-key is set to Frequency Detect ,and press side-key button while it is under standby status. Then the device begins to detecting and decoding. This function cannot detect CTCSS of anti-decoded radios. Press (PTT] button to exit detecting mode. Frequencies change while radio doesn’t start scanning, which means there is complicated electromagnetic nearby. And users should avoid using scanning under strong interference. Once the scanning is done, press [MENU] button to save the scanned frequency and CTCSS on current channel,press [PTT] or [EXIT] to exit. After scanning,if there is standard CTCS,it will show up in standard way. If there is non-standard CTCSS, it will show up as “23b”or “24b” plus a series of numbers. After saving,if you want to check the result, please check Menu->CH Settings->Mute Code.
4.8 FM Function
Long press MI to come into FM radio mode. Long press [ ]/[ ]to searching for signals, or input frequencies manually via keypads. And short press[ ]/[ ]to stop scanning. If you want to receive signals while under FM radio mode, please operate the following steps accordingly: Menu->Set-tings->FM Standby.
4.9 NOAA
Side-key is set to Weather CH and press the side-key to NOAA weather report channels under standby status. Press [ ]/[ ]to switch NOAA channels.

The followings are 11 NOM working frequencies.

4.10 Inputting Method
You can change relative characters via inputting method both in Menu->Setting->Personal ID and Menu->Set-ting->Personal ID
4.10.1 Delete Character
when in Person ID, the display content will be added blank characters automatically to 16 bytes( 2 bytes per Chinese character,1 byte per Digit/English letter/symbol). while in Channel Name, the display content will be added blank characters automatically to 10 bytes. You can move the cursor via [ ] or [ ] to certain place, then press Fi to delete the characters before it.
4.10.2 Inputting of Digit/Symbol/English Letter
When in Personal ID or CH Name status, input numeric keys directly to finish the numeric inputting. Press Pfibutton to input English letter, press relative keys to complete the inputting. Steps to input characters

1. press [#]key to start inputting
2. Press [1]key,open ASCII code table(the table consists of digits/symbols/English letters , and the initial character is blank character)
3. press [ ] or [ ] key to find the needed characters.
4. press the digit key which holds the characters to complete the inputting. The match-up relationship of digit keys and letters [1 Characters] [2 ABC] [3 DEF] [4 GHI] [5 JKL] [6 MNO] [7 PQRS] [8 TUV] [9 WXYZ]
