3. If you find that a zone’s coverage is at unacceptable levels (too small,
too big, extends too far in one direction), look for factors that may be
affecting the zone (food carts, medical equipment, and/or building
construction).
4. If you cannot locate any immediate causes, contact your system
maintenance technician for further assistance.

When finished, deactivate the LED Tag using a TAD.
Identifying Foreign Tag-Activating Sources
In addition to verifying proper zone coverage, an LED Tag (Figure 3.3) can be
used to identify foreign Tag-activating sources to help preserve your Tags’
battery life and prevent nuisance alarms.
Monitored zones emit a Tag-activating signal called the Tx Activation Field.
When a Tag enters a zone’s Tx Activation Field, it is activated. The system
detects the activated Tag and takes appropriate action response.
However, there are sources that can activate a Tag other than a Tx Activation
Field. When Tags are activated by these “foreign” sources, battery life is
depleted and/or nuisance alarms can be caused. Therefore, identifying these
sources will prolong Tags battery life and prevent nuisance alarms.
To identify activating sources with an LED Tag, use the following
instructions:
1. Using a TAD, activate the LED Tag.
NOTE: The Signal Strength LEDs of the TAD will not indicate the
state of the LED Tag. Once activated the LED Tag’s LED will
illuminate when it is in a Tx Activation Field. Therefore, to verify the
LED Tag is active, turn on the TAD and place the LED Tag near it.
The LED Tag’s LED should illuminate (since a TAD has a small Tx
Activation Field associated with it).
2. With the LED Tag in your hand, slowly investigate each area for
possible activating sources*. The LED Tag’s LED will illuminate
when it detects an activating source. Note each activating source and
keep Tags away from those sources.
3.
When finished, deactivate the LED Tag using a TAD.
