TROUBLESHOOTING
The scope will not turn on...
Check that the battery is installed properly. Install the battery according to the (+) and (-) polarity,
ensuring that the markings on the battery and battery compartment correspond with one another.
Check the battery contact to ensure it is clean and free of corrosion; if necessary, clean the contact.
Make sure that the external contact lug is not bent.
If necessary, replace the battery as it may be depleted. Also, be sure that the power is in the “ON”
position when trying to turn on the scope.
Distinct black dots appear on the screen...
These dots are minor cosmetic blemishes resulting from tube production processes and do not
interfere with the reliability or performance of the scope.
The scope flickers, flashes or “snows”...
The scope may flicker or flash when used in a bright environment; to correct this, place the cap over
the objective lens and enter a dark environment. The scope will restore itself to a natural functioning
state in several minutes or hours, depending on how long the scope had been exposed to the light.
The scope may flicker for the first several seconds of use, even when in a dark environment, before
the scope corrects itself and functions properly.
