USER MANUAL
1.2.2 OPTICAL FUNCTIONS
The optical functions include an objective lens, image intensifier, and eyepiece lens. The objective
lens collects light reflected from the moon, stars, or other ambient light in the environment, and
inverts and focuses an image of the scene onto the image intensifier. The image intensifier converts
the captured light into a visible image, re-inverting it so that can be viewed though eyepiece lens.
1.2.3 ELECTRICAL FUNCTIONS
A. Power Source. The electronic circuit is powered by replaceable batteries; you have the option of
using one AA 1.5 Volt Alkaline battery (BA-3O5S/U) or one 1.5 Volt Lithium battery (L91).
B. Power Switch. Power from the batteries is supplied to the components through the RESET/
OFF-ON-IR/PULL switch as follows:
RESET/OFF Position. With the switch in the OFF position, the circuit will not supply energy to
the image intensifier or the IR illuminator. You can also turn the switch to this position to reset
your device after bright light cutoff.
ON Position. Energy is drawn from the battery compartment to power the device. When the
voltage drops to 1.2 VDC, a low battery indicator will begin to blink in the eyepiece, indicating
approximately 30 minutes of remaining power.
IR/PULL Position. Energy is drawn from the battery compartment to power the image
intensifier and IR light source, and a steady red indicator light will appear in the eyepiece.
The IR can be activated momentarily by turning the switch to IR position without pulling the
knob.
C. Bright Light Cutoff. The device will automatically shut off after 70 (±30) seconds of operation in
daylight or bright room light. Individual bright lights (headlights, flashlights, or other concentrated
light sources) will not activate this function, unless the high light detector on the front of the device
is pointed directly at the light source. To turn the device back on in the event that this function is
triggered, flip the switch to RESET/OFF and then back to ON again.
