Night time operation
Take off the objective lens cap.
Switch the unit on by turning the switch into position ON.
In a few seconds greenish fluorescent glow will become
visible through the eyepiece.
Rotate the eyepiece focus adjustment ring until you get
the reticle in focus.
Turn the distance adjustment knob until you get the best
image.
If you need to illuminate the observed object, install and
switch on the optional infrared illuminator.
Warning!
Do not use night-time eyepiece in the daytime.
Do not aim the working night-time eyepiece toward sources of
bright light: lamps, welding, etc. – that may cause decrease of
the light amplification coefficient.
Do not leave the switched on night time eyepiece motionless for
more than 30 minutes in semi-bright conditions to avoid
photocathode fatigue.
Switching the unit off
After you have finished using the unit, turn it off by
rotating switch to OFF position. Ensure the protective
lens cap is on the lens. Remove batteries from the battery
compartment to avoid damage of the device in case of
electrolyte leakage.
