3. Metodi di ricarica
The Gemmac EM03 offers three ways to recharge its internal 5000mAh battery:
3.1 USB Charging (DC 5V Input)
This is the primary and fastest charging method.
- Connect the USB charging cable to the DC 5V input port on the radio and to a USB power source.
- Una carica completa richiede in genere circa 3.5 ore.
3.2 Ricarica a manovella
The hand crank provides power when other charging methods are unavailable.
- Aprire la manovella situata sul retro della radio.
- Rotate the crank clockwise or counter-clockwise at a steady pace (approximately 130-150 RPM) for 3-5 minutes to generate enough power for short-term use (e.g., 15-20 minutes of radio or flashlight).
- Continuous cranking will charge the internal battery.
3.3 Ricarica solare
The solar panel is a supplementary charging method, ideal for maintaining battery charge or for slow charging in direct sunlight.
- Posizionare la radio con il pannello solare rivolto verso la luce solare diretta.
- The solar charging indicator (if available on the display) will illuminate.
- Solar charging is slower than USB or hand crank charging and is most effective for trickle charging or extending battery life.

4. Manutenzione
- Pulizia: Pulire il dispositivo con un panno morbido, damp stoffa. Non utilizzare prodotti chimici aggressivi o detergenti abrasivi.
- Magazzinaggio: Store the radio in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, charge the battery at least once every three months to prolong its lifespan.
