Low Battery Alert
The Yellow LED indicator light will illuminate and remain illuminated when the batteries
are discharged to the point at which the detector has lost 10% of its metal detecting
range.
The audible alert will also lengthen (the tone will sound for a longer period of time)
upon detection of a metal object, when the batteries become discharged to the point at
which the detector has lost 10% of its metal detecting range.
The detector will continue to operate, at a lower sensitivity, when the Low Battery
Indicators are activated. Replace batteries as soon as possible after these indicators
activate.
If you plan to store the GUARDIAN™
for several days or more,
remove the battery.
