7. Charging the Radio

The GR-002G offers multiple ways to recharge its internal battery:

• Micro USB Charging: (Refer to "Initial Charging" in Setup section).
• Hand Crank Charging:
  1. Unfold the hand crank handle located on the back of the radio.
  2. Rotate the hand crank clockwise or counter-clockwise at a steady speed (approximately 130-150 RPM) for 3-5 minutes to generate power.
  3. A short period of cranking can provide enough power for a few minutes of radio use or a brief flashlight burst.
• Solar Charging:
  1. Place the radio with the solar panel facing direct sunlight.
  2. The solar panel will convert sunlight into electricity to charge the internal battery.
  3. Solar charging is primarily for maintaining battery charge or for slow charging in emergencies, not for rapid full charges.
• AAA Battery Power: (Refer to "AAA Battery Installation" in Setup section). When AAA batteries are installed, the radio will draw power from them if the internal Li-ion battery is depleted or switched off.

Maintenance

• Cleaning: Wipe the radio with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Storage: Store the radio in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, ensure the internal battery is partially charged (around 50%) and recharge it every 3-6 months to prolong battery life.
• Battery Care: If using AAA batteries, remove them if the radio will not be used for a long time to prevent leakage.
