Battery Low Indication; Typical Mounting Instructions - Centurion SMART GUARD air Operating Instructions Manual

Battery low indication

Once the batteries start to near the end of their service life,
the SMARTGUARDair will detect the battery low condition
and both visible and audible indications will be provided.
The following indications should be noted by the user:
Visible: The red LED will flash rapidly three times, and
repeat this action every four seconds
Audible: The tone of the onboard buzzer will be
different from its normal pitch during key presses
There will still be a fair amount of usage left before the
batteries are completely drained, but it is advisable to
replace them as soon as possible to ensure continued
operation.
