Operating Instructions

1. Selecting a Channel

Use the Up/Down arrow buttons on the front of the radio to select one of the 22 available channels. Ensure all radios intended for communication are set to the same channel.

2. Using Privacy Codes (CTCSS/DCS)

The PX500 radios utilize 121 privacy codes (38 CTCSS codes and 83 DCS codes) to minimize interference from other users on the same channel. To set a privacy code:

Press the MODE button until the privacy code icon (CTCSS or DCS) flashes on the LCD display.
Use the Up/Down arrow buttons to select your desired privacy code.
Press the MODE button again to confirm and exit.

For successful communication, all radios in your group must be set to the same channel and privacy code.

To Receive: Ensure the PTT button is not pressed. The radio will automatically receive transmissions on the selected channel and privacy code.

4. VOX (Voice-Activated Transmission)

VOX allows for hands-free communication. When activated, the radio transmits automatically when it detects your voice.

Press the MODE button repeatedly until the VOX icon flashes on the LCD display.
Use the Up/Down arrow buttons to select a VOX sensitivity level (1-5, with 5 being most sensitive).
