LOW BATTERY Signal
When the unit detects that the battery voltage is low and needs to be re-
placed, the yellow LED will flash once about every 47 seconds and an alarm
sound BEEP will be issued (see fig10). When the battery voltage is further
reduced, the low voltage indicating cycle is shortened to 12 seconds.
NOTE: The normal stand by time of battery is 3 years minimum. Please
replace the battery in time after the low voltage alarm signal.
It is recommended to use the same type of battery when changing the
battery (2PCS LR03 SIZE AAA 1.5V battery).
