Testing Signal Strength
To initiate a signal strength test, push the Test button on
the sensor (see location of Test button in Figure 102 and
Figure 103).
• Models WZS: LED1, LED2, and LED3 respond by
indicating signal strength. You can view them on the
sensor (Table 66) and the receiver (Ta bl e 6 7).
• Model WDS: Test symbols on the sensor display
indicate signal strength (Tab le 66). LED1, LED2, and
LED3, on the receiver, respond by indicating signal
strength (Table 6 7).
