Its very easy to use and here is even a few tricks:

* If you see a bright white screen, you probably have the camera lens right up against a reflective surface that is bouncing the LED light back into the camera, creating glare. Just pull the probe back a bit.
* If you are working inside a contained area with little or no ambient light, remember that the Led's are providing the illumination. Moving the camera tip in and out a bit can improve lighting on the object for the best screen display.
* When using the mirror for right angle views, clean the mirror glass carefully with a lint-free cloth. Small specks of dirt and dust and fingerprints degrade the screen image. 

FAQ

Q. Can the monitor be used on and off of the hand held?
A. Yes you can either keep the monitor mounted on the hand held or use it remotely.

Q. How far away can the monitor be used away from the hand held?
A. It really depends on the environment you are trying to use it in. 10ft should be expected however you may realize much greater depending on the strength of the batteries at the time and the RF interference at the location you are using the Wireless Inspection Camera.

Q. Is the unit water proof or can it be used in liquid?
A. The image head and cable are water resistant to a standard of IP 67 weather proof. This means the tip can be up to 1 m of submersion but the monitor and handheld must NOT be submersed in way.
