CLEANING THE EYEPIECE
You may need to clean the eyepiece of the Night Storm from time to time in order to guarantee
top performance. When you receive your Night Storm you should check for dust on the
eyepiece of the unit.
First you will need to remove the eyepiece. To do that you will need to initially loosen the 2
set screws that can be found on the base. Then unscrew the eyepiece counter-clockwise to
remove it.
NOTE: You do not have to remove the set screws completely, they are very small and easy to
misplace.
CAUTION: Use only Photographic lens cleaning tissue on these surfaces. Be careful not to
scratch or smudge any of these surfaces. When using compressed air to blow dust away, make
sure to avoid inverting the can while spraying. This can cause frozen propellant to exit the can,
which can cause serious problems with the glass and phosphor screen.
STORAGE AND CARE
• If the device is not to be us d for extended period of time (more than 10 days) remove the
battery.
• Avoid touching lenses. If fingerprints or traces of dirt or dust appear, clean their surface with
a Photographic lens cleaning tissue.
• Keep lens cap/daylight filter on when not in use.
• The Night Storm is not harmful to the user or the environment.
• Do not disassemble except to clean the front lens and eyepiece: it will void your warranty.
• Evaluate the monocular function by looking through it in a lit environment with the daylight
filter lens cap on. Never use in daylight without the daylight filter lens cap on.
• Never point the Night Storm at a bright light source.
• Adverse atmospheric conditions such as fog, smog or haze and a lack of ambient light (moon
or starlight) may diminish the effective viewing distance.
