FUNCTION AND OPERATION

4.1 Transmitting Signal

Press the [PTT] key to transmit. The signal icon ⑰ turns red, and the indicator light turns red.

4.2 Receiving Signal

When the device receives a signal on the current working channel with matching CTCSS/DCS, the indicator light turns green, and the signal icon ⑰ shows up in blue.

4.3 Working Mode Switching

Short press the [#] button to switch between VFO frequency mode and Channel MODE. The icon ⑧ changes accordingly (VHF for VFO, CHXXX for Channel mode).

4.4 Frequency Changing and Repeater Frequency Setting

In VFO mode, manually input frequencies using the keypad (6 digits). For repeater use, set TX frequencies according to the repeater frequency table. Long press the [*] button to enter TX frequency input mode (icon ⑭ turns red). Input 6 digits to set TX frequencies. The screen will then shift to receiving status. Long press [*] again to change transmitting frequencies.

Short press [▲]/[▼] to switch preset working frequencies. Long press [▲]/[▼] for fast switching.

4.5 Channel Switching

In channel mode, input the channel number via keypad or use [▲]/[▼] to switch channels sequentially. Long press [▲]/[▼] for fast switching.

4.6 Air Band Receiving

When the working frequency is set between 108-136MHz, the icon ⑯ shows 'AM', indicating air band receiving status. Transmission is not allowed in air band status.

4.7 Frequency Detecting and Decoding

Set a side-key to Frequency Detect. Press the side-key in standby status to detect and decode frequencies. This function cannot detect CTCSS of anti-decoded radios. Press [PTT] to exit.

If frequencies change while the radio is not scanning, it may indicate strong electromagnetic interference. Avoid scanning in such environments. After scanning, press [MENU] to save the scanned frequency and CTCSS on the current channel, or press [PTT] or [EXIT] to exit. Standard CTCSS will display normally; non-standard CTCSS will show as "23b" or "24b" with numbers.

4.8 FM Function

Long press [0] to enter FM radio mode. Use [▲][▼] to search for signals or input frequencies manually. Short press [▲][▼] to stop scanning. To receive signals while in FM mode, go to Menu -> Settings -> FM Standby.

4.9 NOAA

Set a side-key to Weather CH. Press the side-key in standby status to access NOAA weather report channels. Use [▲][▼] to switch channels. The device will automatically scan NOAA channels if no operation is performed for 2 seconds. NOAA function is available only in supported countries and areas. The 11 NOAA working frequencies are:

• 1: 162.55000MHz
• 2: 162.40000MHz
• 3: 162.47500MHz
