5. Setup
- Charging the Device: Connect the provided USB-C cable to the borescope's charging port and then to a compatible USB power adapter (not included). The battery indicator on the screen will show the charging status. Ensure the device is fully charged before first use.
- Inserting Micro SD Card: Locate the Micro SD card slot on the side of the main unit. Insert a Micro SD card (up to 32GB, often included) with the gold contacts facing down until it clicks into place. This card is necessary for saving photos and videos.
- Attaching the Probe: Align the connector of the 10FT semi-rigid snake cable with the port on the main unit. Push firmly until it is securely connected. Ensure the connection is tight to prevent signal loss.
6. Operating Instructions
- Power On/Off: Press and hold the power button (usually located on the front or side) for a few seconds to turn the device on or off.
- Menu Navigation: Use the directional buttons (Up, Down, Left, Right) to navigate through the on-screen menu options. Press the 'OK' or 'Enter' button to confirm a selection.
- Adjusting LED Brightness: Locate the LED brightness control button (often marked with a light bulb icon). Press it repeatedly to cycle through the 3 available brightness levels for the probe's LEDs.
- 2-Way Articulation: Use the articulation control wheel or joystick (typically on the main unit) to bend the probe tip up to 210 degrees in two directions. Gently manipulate the control to guide the probe.
- Angle Lock: While articulating the probe, press the 'Lock' button to hold the probe tip at a desired angle. This provides stability for detailed inspection or hands-free operation. Press again to release.
- Capturing Photos/Videos: Press the dedicated 'Photo/Video' button (often marked with a camera or video camera icon) to take a still image. Press and hold the same button to start video recording; press again to stop.
- Voice Recording: If available, activate the voice recording function through the menu settings. This allows you to narrate your findings in real-time, which will be synchronized with your video recordings.
- Zoom Function: Use the 'Zoom In' and 'Zoom Out' buttons (often marked with '+' and '-' icons) to apply up to 8x digital zoom on the live image displayed on the 5-inch IPS screen.
- Reviewing Media: Enter the 'Gallery' or 'Playback' mode via the main menu to view captured photos and videos. Use directional buttons to browse and 'OK' to select.
7. Maintenance
- Cleaning: Wipe the main unit with a soft, dry cloth. For the probe tip, use a damp cloth with a mild detergent if necessary, ensuring it is completely dry before storage. Do not use abrasive cleaners or solvents.
- Storage: Store the borescope and all accessories in the provided protective carry case. Keep it in a cool, dry place, away from direct sunlight and extreme temperatures.
- Battery Care: To prolong battery life, charge the device regularly, even if it is not in frequent use. Avoid fully discharging the battery for extended periods.
- Probe Care: Handle the semi-rigid probe cable with care. Avoid sharp bends or excessive force that could damage the internal wiring or articulation mechanism.
