EOTech Holographic Hybrid Sight II EXPS2-2 with G33.STS Magnifier - Manual (Page 18)

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, replacement, or con-
tact the manufacturer (L-3® EOTech®) for repair or replacement.
2.1.2 Battery
One initially supplied (1) 123 Lithium battery powers the EXPS2. 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 pat-
tern blinks off and on during recoil or turns off suddenly, replace the battery. Please read and follow
the battery replacement and battery check procedures described in this Manual. It is always good
practice to replace the battery with a fresh one before a mission.
