2. Consignes de sécurité
- Alimentation: Always connect the transceiver to a stable 12V DC power source capable of supplying sufficient current (minimum 35A, 50A recommended for full power operation). Ensure correct polarity to prevent damage.
- Antenne: Use a properly tuned antenna for the operating frequency. Never transmit without an antenna connected, as this can damage the final amplifier.
- Ventilation: Ensure adequate ventilation around the transceiver to prevent overheating, especially during prolonged transmission.
- Installation mobile : When installing in a vehicle, secure the unit properly to prevent movement during operation. Avoid obstructing airbags or driver visibility.
- Legal Operation: Operate the transceiver in accordance with all applicable local and national regulations for amateur radio.

5. Installation
5.1 Installation mobile
- Select a suitable location in your vehicle that allows for easy access to controls and display, without obstructing driving or safety devices.
- Use the provided mounting bracket and hardware to securely fasten the transceiver.
5.2 Connexion d'alimentation
- Connect the red wire of the DC power cord to the positive (+) terminal of your 12V DC power source (vehicle battery or regulated power supply).
- Connect the black wire to the negative (-) terminal or a good chassis ground.
- Ensure the inline fuse is properly installed.
- For optimal performance, especially at high power, ensure your power supply can deliver at least 35 Amperes, with 50 Amperes recommended.
5.3 connexion d'antenne
- Connect a 10 or 12 meter amateur band antenna, tuned for the desired operating frequencies, to the SO-239 connector on the rear panel.
- Ensure the antenna cable has a low SWR (Standing Wave Ratio) for efficient power transfer and to prevent damage to the transceiver.
5.4 Connexion du microphone
- Plug the microphone connector into the designated jack on the front panel.
6. Mode d'emploi
6.1 Mise sous/hors tension
- Turn the VOL knob clockwise to power on the transceiver. The display will illuminate.
- Turn the VOL knob counter-clockwise until it clicks to power off.
6.2 Réglage du volume et du squelch
- Volume: Adjust the outer ring of the VOL/SQUELCH knob to set the desired audio output level.
- Écraser: Adjust the inner knob of VOL/SQUELCH clockwise until background noise disappears. Set it just past the point where the noise is silenced.
6.3 Sélection du mode
- Rotate the MODE selector knob to choose between AM (Amplitude Modulation), FM (Frequency Modulation), USB (Upper Sideband), LSB (Lower Sideband), or CW (Continuous Wave).
6.4 Réglage de la fréquence
- Rotate the main VFO/Channel knob to change the operating frequency.
- Use the UP/DOWN buttons on the microphone or front panel for fine-tuning or stepping through frequencies.
6.5 Fonctions de mémoire
