Batteries
The GR-3 receiver comes equipped with two detachable,
rechargeable batteries (Figure 1-2) for powering the receiver.
Figure 1-2. GR-3 Batteries
The receiver draws power from one battery at a time before switching
to the second battery. Each detachable battery can provide between
4h30m and 8h30m (approximate) of operation, depending on the
mode of the receiver.
The battery charging cradle (Figure 1-3) connects to a standard
power outlet using the power adapter cable and power cable/power
supply unit. When connected to a power outlet, the batteries are fully
charged in approximately six hours. The batteries should run at no
less than 80% capacity after 500 charging cycles. These batteries do
not need to be drained before recharging.
The charger has two ports, one button, and three LEDs.
• The two ports connect the charger to either a receiver or an
external power source. The ports charge or drain the batteries
simultaneously.
