2.1.1. PREPARATION FOR USE
This chapter contains the information necessary to prepare the
scope for operation. This includes unpacking, examination for da-
mage, and batteries installation.
A. Unpacking.
The following steps must be accomplished prior to each mission
where the sight is used.
1. Open carrying case, remove the scope and check contents for
completeness.
2. Inspect the scope for obvious evidence of damage to optical
surfaces, body, eyecups, operation buttons, etc. Ensure that all
optical surfaces are clean and ready for use. Clean with lens
tissue.
B. Installation of Batteries.
WARNING
The lithium battery contains sulfur dioxide gas under pressure.
Do not heat, puncture, disassemble, short circuit, attempt to
recharge or otherwise tamper with the batteries.
Turn off equipment if battery compartment becomes unduly hot.
If possible, wait until the batteries have cooled before removing
them.
If you inhale sulfur dioxide, seek medical attention.
The ThOR will operate with four CR123A Lithium batteries type.
Install CR123A Lithium batteries as follows.
1. Open the battery compartment cover by unscrewing the screws
counterclockwise.
2. Observe polarity, as indicated on the inside of the battery com-
partment, and insert four 3.0 Volt CR 123A Lithium batteries into
the battery compartment.
3. Replace compartment cover and screw two fixing screws. Tight-
en screws firmly to ensure a watertight seal.
