Diagnostics
LED1, LED2, and LED3, located on the receiver of all models, respond to diagnostics by exhibiting
specific blinking patterns. They respond independently of any user action (see Table 39).
Testing Signal Strength
To initiate a signal strength test, push the Test button on the sensor (see location of Test button in
Figure 31, p. 116).
• Models WTS: LED1, LED2, and LED3 respond by indicating signal strength. You can view them
on the sensor (Tab l e 40) and the receiver (Ta bl e 41, p. 118 ).
• Mo
del WDS: Test symbols on the sensor display indicate signal strength (Ta b le 40). LED1, LED2,
and LED3, on the receiver, respond b
y indicating signal strength (Ta bl e 41, p. 11 8).
