Configuration et installation

Proper setup is crucial for optimal performance and safety. Ensure all connections are secure before powering on the unit.

1. Connexion électrique

Connect the radio to a stable 13.8V DC power source. A 14.2V source is recommended for best performance. Ensure correct polarity (red to positive, black to negative) to prevent damage to the unit.

2. Connexion de l'antenne

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. Connexion du microphone

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

4. Mise sous tension initiale

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