5-6 the Receiver Installation Manual
Adjusting the Receiver
The Receiver is factory set for optimum
performance, and as such, it should
NOT
be
necessary for you to make any adjustments to it.
NOTE: If you are trying to eliminate crosstalk
(activated Tags from one zone being detected in
another zone), implement Stagger Tuning
(page 4-6).
However, there are a couple of exceptions:
 When protecting a wide hallway or
passageway, it may be necessary to
increase Receiver sensitivity to assure
optimum detection.
 When unavoidable background noise (such
as from permanent medical equipment or
wireless communication devices) is
present, it may be necessary to reduce
Receiver sensitivity.
IMPORTANT:
Adjusting the Receiver can cause Supervise
alarms. Notify staff and security that you will
be adjusting (and possibly weakening) the
zone and they will need to pay special
attention to area traffic during this time.
To adjust a Receiver, refer to Figure 5.1 or 5.2
and use the following instructions:
1. Around the access hole for
potentiometer R19 on a Receiver, a
decal marks the minimum and
maximum settings. The factory setting is
approximately halfway between the
minimum and maximum marks. The
Receiver will not work outside these
marks. When adjusting, it is best to stay
within 1/16” of a turn of the factory
setting.
2. As you adjust, remember to verify that
there is adequate zone coverage.
3. To decrease the Receiver’s sensitivity,
slowly turn potentiometer R19
clockwise toward the minimum setting
on the R19 decal.
4. To increase the Receiver’s sensitivity,
slowly turn potentiometer R19
counterclockwise toward the maximum
setting on the R19 decal.
