2. Conexão da Antena

Connect a suitable 10-meter amateur radio antenna to the UHF SO239 connector on the rear of the radio. Use high-quality coaxial cable with proper impedance (typically 50 ohms) for efficient power transfer and minimal signal loss. Ensure the antenna is properly tuned for the 10-meter band.

3. Conexão do microfone

Plug the supplied microphone into the front microphone jack. Ensure the connector is fully seated.

4. Ligação inicial

Once all connections are made, turn the radio on using the ON/OFF/Volume control. The display should illuminate.
