5.1. Replacing The Battery
To replace the QRAE 3 battery:
1. Remove the two screws that hold the battery compartment cover in place.
Note:
It is not necessary to remove the belt clip.
2. Remove the cover plate by tilting up the end closest to the belt clip and lifting off.
3. Slide the QRAE 3’s battery out of its compartment and into your hand.
4. Press a fully charged battery into the battery compartment and place it in the instrument. Pay
careful attention to the direction of the battery so that the electrical contacts are on the bottom.
5. Replace the cover and tighten the two screws to secure the battery.
5.2. Battery States
The battery icon on the display shows how much charge is in the battery and alerts you to any
charging problems.
Full charge 2/3 charge 1/3 charge Low charge Battery alert
When the battery’s charge falls below a preset voltage, the instrument warns you by beeping
once and flashing once every minute, and the “empty battery” icon blinks on and off once per
second. The instrument automatically powers down within 10 minutes, after which you will
need to either recharge the battery, or replace it with a fully charged one.
