Using the Detachable Batteries
The GR-3 receiver comes with two detachable, rechargeable batteries
and an AA battery shell. Each battery can provide between 4.5 and
8.5 (approximate) hours of operation at room temperature, depending
on the mode of the receiver and the capacity of the battery.
To attach the batteries (Figure 2-14):
1. With the battery slightly tipped, place the bottom of the battery
into the bottom of the battery pocket.
2. Gently push the top of the battery into the battery pocket until it
snaps into place. Make sure that the clip at the top of the battery
completely snaps into place.
