LR-400 Charging Batteries

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 trans-
former 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.
One of several charging cases available from Listen. Check the Listen web-
site for more details.
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.
IMPORTANT: 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.

into an AC wall
outlet.
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.
