Battery Charging Information

The LR-200-072 receiver uses a trickle charging method. When one of these receivers is placed into a Listen charging case any NiMH batteries will be charged. The entire charging process takes 10-12 hours under normal conditions.

During the charging cycle, the red LED on top of the Listen product will remain illuminated.

When not using the receiver, it is recommended to leave the unit in the charging case or plugged into the LA-202 power source. If the unit is not on the charger, the battery will lose up to 20% of its charge per month.

NOTE: Listen provides 2300 mAH (milli-Amp-hour) constant current NiMH Nickel Metal Hydride batteries. These may be purchased from Listen (LA-362).

Charging with a drop-in charger

To charge the batteries using a drop-in charging case, simply place the unit into a slot in the charging case and connect the case to power. Make sure the unit is fully seated in its slot.
