- Power Off: After use, press and hold the power button to turn off the borescope.
7. Maintenance
- Cleaning the Probe: After each use, especially in dirty or oily environments, gently wipe the camera lens and probe with a soft, damp cloth. For stubborn grime, a small amount of isopropyl alcohol can be used. Ensure the probe is dry before storage.
- Cleaning the Main Unit: Wipe the display and main unit with a dry, soft cloth. Do not use abrasive cleaners or immerse the main unit in water.
- Battery Care: Recharge the battery regularly, even if the device is not used frequently, to maintain battery health. Store the device with a partially charged battery (around 50%) if storing for extended periods.
- Storage: Store the borescope and its accessories in the provided carrying case in a cool, dry place, away from direct sunlight and extreme temperatures.
