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

Two initially supplied AA Alkaline batteries power the 558. The HWS is designed to maintain

constant brightness at a particular setting as the batteries drain down. The reticle brightness

will not fade gradually as the batteries run down, but rather, shut down abruptly. The first indica-

tion of the batteries draining is the reticle blinking when the unit is turned on (see Electronic

Features 2.1.4). Another indication of low batteries is the reticle pattern blinking off and on dur-

ing 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

batteries. Please read and follow the battery replacement and battery check procedures

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

before a mission.
