Testing Signal Strength
To initiate a signal strength test, push the Test button on
the sensor (see location of Test button in
Figure 60 and
Figure 61 ).
• Models WZS: LED1, LED2, and LED3 respond by
indicating signal strength. You can view them on the
sensor and the receiver (tables below).
• Model WDS: Test symbols on the sensor display
indicate signal strength. LED1, LED2, and LED3, on the
receiver, respond by indicating signal strength. See the
tables below for symbol displays.
