Battery Operation
The AirGuard is a battery-operated portable instrument and should be fully charged before use.
To charge the AirGuard, you must connect the charge connector cable to the charging inlet located on the lower
right side of the instrument. Insert the 2.5mm Ault connector into the female receptacle, secure the connector by
screwing it together, clockwise and then power the charger by connecting to main or wall power 100 to 240VAc
power.
The battery can power the AirGuard for 16 hours of operation.
The AirGuard will indicate a low battery in two ways, one through the main display battery icon turning red. The
other is a screen warning that will appear on the LCD.
If the charger is not connected the LCD will power down to conserve remaining battery power.
