Aligning The Beam - Radio Shack Invisible Beam Entry Alert Owner's Manual

4. Remove the protective paper from the adhesive strips on
the back of the reflector and press the reflector onto the
other half of the bracket.
5. Attach the half of the bracket with the reflector to the half
you mounted on the wall in Step 3, using the two supplied
machine screws with attached washers.
Note: Do not tighten the machine screws until after you adjust
the reflector's angle (see "Adjusting Sensitivity" on Page 11).

ALIGNING THE BEAM

After you mount the alert and reflector, and connect power, you
must make sure they are aligned correctly.
1. Check the angle adjustment by looking into the hole on the
side of the alert's mirror box, above the lens head.
Note: If you cannot look into the hole on the mirror box
from one side, slide the box out, turn it upside down, and
reinstall it with the round hole facing toward the front. Then
look into the mirror box from the other side. You can leave
the mirror box in this position.
If you do not see the reflector through the hole, you can
adjust the reflector's angle as much as 10° from the center
position. Slightly tilt the reflector until it is at the desired
angle, then tighten the screw.
You can adjust the lens angle as much as 10 vertically and
5 horizontally.
