LR-400 Charging Batteries

LR-400 Charging Batteries continued

During the charge cycle, the red LED on top of the Listen product will flash slowly. When charg-
ing is completed, the LED will turn off. It is not necessary to unplug the charger; however, if you
unplug the unit from the charger and then plug it back in, it will begin the 13-hour charge cycle
over again.
When not using the LR-400, it is recommended to leave the unit on the charger. The charger
provides a “maintenance” charge that keeps the battery at 100%. If the unit is not on the charger,
the battery will lose up to 20% of its charge per month.
NOTE: Listen uses 1800mAh (milli-Amp-hour) constant current
NiMH (Nickel Metal Hydride) batteries. These may be purchased
from your Listen dealer (ask for part number LA-362).
One of several charging cases
available from Listen. See the
www.ListenTech.com for more
options.
