Testing the Battery
The XM3 will warn you if the power falls below certain
thresholds:
•
At around 6.5 volts, the amber LED will begin
to flash.
•
Below around 5.2 volts, the amber LED will
double-flash, indicating the battery is very low.
The XM3 also acts as a battery tester.
When the XM3 is initially turned on, the amber LED will display the
battery voltage by flashing. For example, if the voltage is 8.5 volts,
the LED will flash 8 times, then 5 times.
To see the battery voltage if the unit is already on, press the power
button once.
