Action 1: Battery-related alarms
Check whether the battery is connected. When the power is
turned on for the first time after the battery is connected, a
battery zero alarm occurs. In this case, turn the power off then on
again. If the alarm occurs again, check the battery voltage. If the
battery voltage drop alarm occurs, check the voltage, then
replace the battery.
