5. OPERATION INSTRUCTIONS
Installing battery
Unit is supplied without a battery installed.
Prior to installing the battery, make sure the On/Off/IR/Auto
switch (1, Fig.1) is in the OFF position and the objective lens
cap is on.
The Unit can operate on either a single AA or CR-123 lithium
battery. Lithium batteries hold a charge longer than conventional
batteries and provide better performance at low temperatures.
To install a battery remove the battery compartment cover (6,
Fig.1) by rotating it counter clockwise. When using a CR-123
lithium battery, remove the battery bushing located under the
battery compartment cover by rotating it counter clockwise.
Store the bushing in a safe place while not in use. Make sure the
battery is installed with the correct polarity as indicated on the
housing. Insert the battery and replace the battery cover.
Activating the Unit
In daylight ensure the objective lens cap is in place prior
to activating the Unit.
To check if the Unit is operational switch it ON by rotating the
On/Off/IR/Auto switch clockwise while looking through the
eyepiece (4, Fig.1). You should see either a green or black and
white image (depending on the model you have purchased). If
