Charging Batteries - Listen Technologies LR-300 User Manual

LR-400 Charging Batteries
The LR-400 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.
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.
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.
