Testing Battery Status
Initiate a battery status test as follows:
• On the WZS, push the Test button on the sensor (see
location on Figure 103, p. 125). LED5 on the sensor
responds by indicating the level of battery strength, as
shown in Table 48, p. 128.
• On the WDS, push the Test button on the sensor (see
location on Figure 104, p. 125). In response, a battery
test symbol appears on the display. The symbol shown
indicates battery life expectancy (see Table 49, p. 128).
