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.
