Sensor Diagnostics

LED1, LED2, and LED3, located on the WZS respond to
diagnostics by exhibiting specific blinking patterns. View
their response by pressing the Test button.

Testing Signal Strength

To initiate a signal strength test, push the Test button on the
sensor (see location of Test button in
and Figure 104, p. 125.
Models WZS: LED1, LED2, and LED3 respond by
indicating signal strength. You can view them on the sensor
(Table 46, p. 127) and the receiver
