battery select switch is in the correct position. Charging will only occur when the
Listen product’s battery selection switch is set to the “NiMH” position. This switch
is located inside the battery compartment of the product.

Warning: Do not attempt to charge alkaline batteries. This may damage the unit
and case, and will void the warranty!
Turn units to be charged OFF.
For optimal charging, receivers and transmitters should be turned OFF* during
the charge cycle. Portable transmitters manufactured prior to 2003 require that
the unit be turned ON to begin charging. Once charging begins, turn the
unit OFF.

LA-321/324 Charging Instructions (cont.)
Place units in charging slots.
It may be necessary to press the units down
into the pocket to ensure that it is touching
the charging contacts.
5
Verify units are charging.
Watch units for 10 seconds before leaving them to charge. Once placed in the
charging slots, the red LED on top of Listen’s portable receivers and transmitters will
glow continuously for 1-2 seconds, then extinguish. The units will then evaluate
battery status for 5-7 seconds. If the battery select switch is positioned in the NiMH
setting, the red LED will begin to flash indicating that the units are charging.
NOTE: If batteries are completely discharged, the red LED will remain solid while the
batteries are reconditioned. Unit should begin flashing after 5-10 minutes. The
LED may flicker during the reconditioning process.
Verify Full Charge.
Each unit’s red LED will stop flashing once charging is complete. Charging time for
full recharge on completely discharged batteries is 13 hours.
NOTE: If a unit is removed from the case during the charge cycle, and then
reinserted, it will begin a new charge cycle.
WARNING: The case lid MUST be open or removed while the units are charging. The
charging process generates heat and ventilation is required. It is best to
store your charging case at room temperature away from heat sources
and direct sunlight.
