turn off the Main Power Switch on the Junction Box.
Trigger Beam and Emitter Lenses

2. Clean each lense with a cotton swab, lens tissue, or a soft cloth.
Do not use paper towels because they are abrasive and can
scratch the lense.

on the trigger raising mechanism. Be careful not to disturb the
trigger raising mechanism.
4. Inspect the beacons for cracks in the lenses and moisture inside
the lenses.

2. Clean each sensor with a cotton swab, lens tissue, or a soft
cloth. Do not use paper towels because they are abrasive and
