Maintenance and Care
- Cleaning the Probe: The camera probe is IP67 waterproof. After use in dirty or wet environments, gently wipe the probe with a damp cloth. For stubborn dirt, a mild detergent can be used, followed by a clean, damp cloth. Ensure the probe is dry before storage.
- Cleaning the Main Unit: The main unit is not waterproof. Clean it with a soft, dry cloth. Avoid using liquid cleaners or abrasive materials.
- Storage: Store the endoscope in a cool, dry place, away from direct sunlight and extreme temperatures. Coil the semi-rigid cable loosely to prevent damage.
- Battery Care: To prolong battery life, charge the device regularly, even if not in frequent use. Avoid completely draining the battery for extended periods.
- SD Card Management: Periodically transfer photos and videos from the Micro SD card to a computer to free up space and back up your data. Format the SD card through the device's menu if performance degrades.
