Preparation
Battery Indicators
An indicator will sound when the battery voltage is
low. You have approximately 5 minutes* to replace the
battery. An indicator will sound just before the battery
stops working.
* Actual time between low battery indicator and shut down
will vary depending on environmental noise levels and
brand of battery used.

Use an appropriate tool to slide

To unlock the battery door:
Slide the recessed switch to the
