Note: Do not use a USB-C charger with this device. Only use the provided desktop charger.
5.3. Attaching the Antenna
- Screw the antenna clockwise into the connector on the top of the radio until it is finger-tight.
- Do not overtighten the antenna.
6. Operating Instructions
6.1. Power On/Off and Volume Control
- Power On: Rotate the Power/Volume knob clockwise until you hear a click. The display will light up.
- Power Off: Rotate the Power/Volume knob counter-clockwise until you hear a click.
- Volume Adjustment: Rotate the Power/Volume knob clockwise to increase volume and counter-clockwise to decrease it.
6.2. Channel and Frequency Selection
The RT-600 supports 200 storage channels and direct frequency input.
- Channel Mode: Use the UP/DOWN arrow keys to navigate through stored channels.
- Frequency Mode (VFO): Enter frequencies directly using the keypad. Press the 'VFO/MR' button to switch between VFO (Frequency) and MR (Memory/Channel) modes.
6.3. One-Key Frequency Copy (Automatic Frequency Capture)
This feature allows your RT-600 to quickly copy the frequency and CTCSS/DCS tone from another radio, enabling instant communication.
- Place the two radios (your RT-600 and the target radio) within 1 meter of each other.
- Activate the one-key copy function on your RT-600 (refer to your radio's specific key assignment for this function, often labeled 'FC' or similar).
- The RT-600 will scan and capture the frequency and tone from the transmitting radio.
- Once copied, your RT-600 will be set to communicate on that frequency.
6.4. Air Band Reception (108-136MHz AM)
The RT-600 can receive AM signals in the air band frequency range.
