5. Operation
5.1 Powering On/Off
Press and hold the power button on the control box/monitor unit to turn the system on or off. The 7-inch TFT HD color display will illuminate.

5.2 Camera Control and Self-Leveling
The camera head features a self-leveling function, ensuring the image remains upright regardless of the camera's orientation within the pipe. This is achieved via an integrated gravity sensor.

The camera head is equipped with 12 adjustable white LED lights. Use the dedicated control knob or buttons on the monitor unit to adjust the brightness of these LEDs to suit the inspection environment. This ensures clear visibility even in dark conditions.
5.3 Cable Management and Meter Counter
The 100ft (30m) fiberglass cable is semi-rigid, providing good handling characteristics for navigating pipes. The cable features clear Arabic numerals marked at regular intervals, allowing you to accurately measure the camera's insertion depth into the pipes.

When inserting the camera, gently feed the cable into the pipe. For retrieval, carefully reel the cable back onto the spool, avoiding sudden pulls or twists.
5.4 Applicable Pipe Sizes
This camera system is suitable for:
- Straight pipes: 25mm (1 inch) diameter and larger.
