6. Maintenance
6.1 Cleaning the Device
- Lenses: Use a soft, lint-free cloth specifically designed for optical lenses. Gently wipe the lens surface. For stubborn smudges, use a small amount of lens cleaning solution applied to the cloth, not directly to the lens.
- Body: Wipe the device body with a soft, damp cloth. Do not use abrasive cleaners, solvents, or strong chemicals.
- Avoid excessive moisture: Ensure all port covers are securely closed before cleaning or if exposed to light rain.
6.2 Battery Care and Storage
- Regular Charging: For optimal battery life, avoid completely draining the battery frequently. Charge the device regularly.
- Long-Term Storage: If storing the device for an extended period, charge the battery to approximately 50-70% capacity. Store in a cool, dry place away from direct sunlight. Recharge every 3-6 months to prevent deep discharge.
