Operator's Manual

2.1.1 Hood

The HWS is equipped with a protective hood. This hood is pre-assembled at the factory. Should

your hood require repair or replacement, please contact your unit armorer for repair, replace-

ment, or contact the manufacturer (L3 EOTECH) for repair or replacement.

2.1.2 Battery

One initially supplied (1) 123 Lithium battery powers the EXPS3. The HWS is designed to

maintain constant brightness at a particular setting as the battery drains down. The reticle

brightness will not fade gradually as the battery runs down, but rather, shut down abruptly. The

first indication of the battery draining is the reticle blinking when the unit is turned on (see

Electronic Features 2.1.4). Another indication of a low battery is the reticle pattern blinking off

and on during recoil. With high recoil guns, this can occur before the battery check indicates

low battery condition. If the reticle pattern blinks off and on during recoil or turns off suddenly,

replace the battery. Please read and follow the battery replacement and battery check proce-

dures described in this Manual. It is always good practice to replace the battery with a fresh

one before a mission.
