Testing Signal Strength
To initiate a signal strength test, push the Test button on the sensor (see location of Test
button in Figure 10, p. 35).
• Models WTS, WZS: LED1, LED2, and LED3 respond by indicating signal strength. You
can view them on the sensor (Tab le 4 ) and the receiver (Table 5, p. 38).
• Model WDS: Test symbols on the sensor display indicate signal strength (Tabl e 4).
LED1, LED2, and LED3, on the receiver, respond by indicating signal strength (Tab l e 5,
p. 38).

Satisfactory signal strength
• Adequate signal strength for reliable communication.
• Moving sensor or receiver may improve signal
strength.
• Increased channel switching may reduce battery
life.
