4. Initial Power On and Activation
Press and hold the power button (usually located on the side or top) until the display screen illuminates. The radio will boot up and attempt to connect to the cellular network. For some units, activation with the seller may be required. The device IMEI number, displayed on the startup screen, and the SIM card number may be needed for this process. Refer to the seller's instructions for activation if necessary.
Operating Instructions
1. Power On/Off
To power on, press and hold the power button until the screen lights up. To power off, press and hold the power button until the shutdown prompt appears, then confirm.

3. Push-to-Talk (PTT) Communication
To transmit, press and hold the large Push-to-Talk (PTT) button, usually on the side of the radio. Speak clearly into the microphone. Release the PTT button to listen. Note that with digital PoC radios, there might be a slight delay (approx. 2 seconds) before transmission begins after pressing PTT.
4. Group and Private Calls
The SHJ 4G PoC Radio supports both group and private (one-to-one) calls. The method for switching between groups or initiating private calls depends on the radio's software configuration. Typically, this involves navigating through the menu using the directional buttons and selecting the desired contact or group. If you are unable to create private groups or manage contacts, contact your seller for specific programming instructions or software tools.
