Connect the Type-C charging cable to the port on the radio, or place the radio in the desktop charger. Connect the charger to a power source. The charging indicator will show the charging status. Ensure the battery is fully charged before first use.
6. Operating Instructions
6.1 Power On/Off and Volume Adjustment
To power on the radio, rotate the Volume/Power knob clockwise until you hear a click. To power off, rotate it counter-clockwise until it clicks. Continue rotating the knob clockwise to increase volume and counter-clockwise to decrease it.
6.2 Channel/Frequency Selection
Use the up/down keys or the keypad to select desired channels or enter specific frequencies. The LCD screen will display the current selection.
6.3 Transmitting and Receiving (PTT)
To transmit, press and hold the PTT (Push-to-Talk) button on the side of the radio. Speak clearly into the microphone. Release the PTT button to return to receive mode.
6.4 Frequency Measurement (Auto Frequency Capture)
The RT-470X features a one-key copy frequency function. This allows the radio to automatically scan and capture the frequency and CTCSS/DCS tone of another radio within approximately 1 meter, enabling immediate communication without manual programming.

7. Advanced Features
7.1 Voice Scrambler Function
When activated, the Voice Scrambler function encrypts your voice transmission, preventing unauthorized listeners from understanding your conversation, even if they are on the same frequency and sub-tone. Both radios must have the scrambler activated to communicate.
