Answers to questions on Subtech Mfg.'s Drain Camera Equipment & Systems

What do I do if the video screen is not turning on ?


1. Check toggle switch on the rear of the monitor.

2. Check interface cord is connected securely from the reel to the monitor.

3. Make sure the unit is plugged into an electrical outlet (the AC wall adapter that came with the unit must be used, using an aftermarket plug will void the warranty and may cause major system damage).

4. Make sure the battery is fully charged if on battery power.
