Testing Battery Status
Initiate a battery status test as follows:
• On models WTS and WZS, push the Test button on the sensor (see location on
Figure 10, p. 35). LED5 on the sensor responds by indicating the level of battery
strength, as shown in Tab le 6.
• On model WDS, push the Test button on the sensor (see location on Figure 10, p. 35).
In response, a battery test symbol appears on the display. The symbol shown
indicates battery life expectancy (see Table 7, p. 39).

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

Solid green for 5 seconds Battery is adequate for proper operation.
Solid red for 5 seconds 25% battery life left. Batteries should be replaced.
No light Batteries life expired or not installed properly, or sensor is

times. Cycle repeats every 15 minutes.
Approximately 14 days of operation remain before the battery
is too weak to power the sensor.
