EOTech 553 - Manual (Page 31)

Failure: The reticle is flashing/ flashing on and off/ unit turns off during recoil:
Corrective Action 1: This is the low battery indicator. Replace the batteries.
Corrective Action 2: If the batteries are low, a high recoil weapon platform can cause
the reticle to flash on and off, even before the low battery indicator takes effect.
Replace the batteries.
Corrective Action 3: Replace the battery with Energizer brand batteries. These have
proven to be the most effective to withstanding a consistent amount of recoil. Many
brands of batteries deteriorate faster than others and can result in these failures.
Corrective Action 4: Turn the sight in for unit level maintenance.
Failure: There is a streak in the reticle/ the reticle is dim/ the reticle fades in parts of the window:
Corrective Action 1: Replace the batteries.
Corrective Action 2: Check with others who have used the sight, and compare what
you see to ensure it is not your focal acuity prior to turning the sight in for repair.
Corrective Action 3: Turn in for unit level maintenance.
