Charging Batteries - Listen Technologies LR-300 User Manual

LR-500 Charging Batteries
The LR-500 and all Listen receivers are unique because they have SmartCharge™ chargers
built in. When any of these units are connected to an LA-202 wall transformer or dropped
into a Listen charging case, NiMH batteries will be charged.
1
To charge the batteries using the LA-202 wall transformer,
plug the transformer into the jack marked "PWR/CHG" on
the side of the unit. The unit can be operated while the
batteries are charging.
2
To charge the batteries using a drop-in charger, simply place
the unit into a slot in the charger and connect the charger to power.
Make sure the unit is fully seated in its slot.
SmartCharge™ uses a pulse charging, which greatly extends the life of
Nickel Metal Hydride (NiMH) batteries. The entire charging process takes
13 hours. Listen recommends that you allow the charger to complete its full
cycle every time for maximum battery life.
NOTE: In order to charge NiMH batteries, the BATTERY SELECT switch in your
Listen product must be set to the NiMH setting. Use a pen or small
screwdriver to move the switch (located in the battery compartment)
to the proper position.
IMPORTANT: DO NOT ATTEMPT TO CHARGE ANY TYPE OF BATTERY OTHER THAN NiMH (NICKEL METAL
HYDRIDE) with your Listen equipment. Alkaline batteries may explode when connected
to a charger. Other risks of charging non-NiMH batteries include destruction of
property or fire.
