Care

Modifying or tampering with the alert’s internal components can

cause a malfunction and might invalidate its warranty. If your

alert is not performing as it should, take it to your local

RadioShack store for assistance.

REPLACING THE FUSE

Check the fuse if the external siren (or another connected secu-

rity device) is inoperative. If the fuse is blown, replace it with a

fuse of the same size and type, rated at 0.5 A, 250V (available

at your local RadioShack store).

1. Unplug the AC adapter and disconnect the backup DC

source (if necessary).

2. Loosen the screw on the door on the side of the alert and

open the door.

The reflector surface is

not set parallel to the front

of the alert.

Readjust and/or reposition the

alert and/or reflector.

The sensor lenses are

obscured with dust, lint, or

other contaminants inter-

fering with beam recep-

tion.

Clean lenses using a non-

abrasive lens cleaning solu-

tion and a lint-free cloth.
