Self Test
The battery test finds out if the batteries can provide backup power. It is started from the Param-
eters menu (Figure 3.1). This should not be done for the first 24 hours after a new unit is in-
stalled so the batteries can be fully charged. Every 30 days, the unit automatically does a battery
discharge test. If it finds a problem, it is displayed on the LCD.
Procedure

If no buttons are pushed for 10 seconds, the LCD exits this menu and displays the operat-
ing mode.
