Troubleshooting
1.The screen will not glow while in the on position: Check battery. Make sure it is charged and installed properly.
2.The image fades or disappears completely: If you are in complete darkness, the scope needs some light. Activate the Illuminator (#6). It is possible that you pointed the device at an intense light source which might have shut down the unit to protect the intensifier tube. Turn the power off and wait five minutes before turning it back on.
3.Unable to properly focus: Try adjusting the focus on both the Eyepiece (#1) and the
Objective Lens Ring (#4) Also, try cleaning the lens with professional supplies.
