4.1 Charging the Battery

The Trevi RA 7F50 BT radio is equipped with a rechargeable lithium battery (1500 mAh) and offers two charging methods:

• USB Type-C Charging: Connect the provided USB Type-C cable to the radio's charging port and the other end to a standard USB power adapter (not included) or a computer's USB port. The charging indicator light will illuminate.
• Solar Charging: Place the radio with its solar panel facing direct sunlight. The integrated 80 mA solar panel will slowly recharge the battery. This method is ideal for maintaining charge or for emergency power in outdoor environments.

It is recommended to fully charge the battery before first use.
