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

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.  
8
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.

Removable Charging Platform  
Listen 8 and 16 slot charging platforms can be used without the carrying case. If you desire to place  
the platform on a table, shelf or in a drawer to minimize the space required for charging, the foam  
platform can be used separately. The removable charging  
platform is available on the 8 and 16 unit charging cases  
only (LA-321, LA-324, LA-311 and LA-325).  
To Remove Platform:

NiMH Battery Technology  
Listen LA-362 NiMH batteries are industrial grade and provide constant current to Listen products.  
These batteries provide 2100 milliamp hours (mAh) of storage capacity. When used with Listen  
supplied batteries, Listen products should provide the following operational time after batteries are  
fully charged:  
Receivers:  
15 hours  
Transmitters: 8 hours  
Listen recommends that new batteries be put through two-charge cycles prior to use.  
Nickel Metal Hydride (NiMH) batteries have no memory effect, so each charge offers full  
recharge capacity.  
NiMH batteries can be repeatedly charged to full capacity from any level of capacity.  
NiMH batteries typically maintain optimal performance for 500 to 700 charge cycles. Listen  
recommends that batteries be replaced after 2 years of service or whenever the batteries  
no longer hold a charge.  
Please note that NiMH batteries should be recharged if they have been sitting idle for more than  
two months, as they lose around 20-30% of their charge each month.  
To avoid battery discharge while not using Listen products, it is recommended to leave units in a  
powered case, as the maintenance charge will ensure the batteries remain at full charge. Make  
sure the case lid remains open or removed. The charging process generates heat and ventilation  
is required.

possible to turn units on when placing them in carrying pockets.  
The red LED on my portable product does not flash when connected in charging case (which  
indicates charging is not occurring.)  
Make sure unit’s volume wheel remains in the “off” position when stored in the case. It  
is possible to turn units on when placing them in carrying pockets. Check that there is  
power to the case, this is verified by the green LED next to the power connection being  
lit. The batteries may be completely discharged. In this situation, leave the unit in the  
charging case for 5-10 minutes, while the batteries are reconditioned. Verify tight  
connection between charging wire and unit. Verify unit battery switch is in NiMH position.

8-Unit & 16-Unit Troubleshooting  
Troubleshooting  
The red LED on my portable receiver does not flash when product is placed in the charging case  
(which indicates charging is not occurring.)  
Check that there is power to the case, this is verified by the green LED next to the power connection  
being lit. Make sure that the plug underneath the removal charging platform is connected. Verify unit  
is seated correctly and is making contact with the charging pins. Some minor adjustments of the unit’s  
position in the charging pocket may be required. The batteries may be completely discharged. In this  
situation, leave the unit in the charging case for 5-10 minutes, while the batteries are reconditioned.  
Verify unit battery switch is in NiMH position.  
The red LED on the LT-700 does not flash when product is placed in the charging case  
(which indicates charging is not occurring.)  
Verify issues related to portable receivers are not present. If unit was manufactured prior to 2003, unit  
will need to be turned “on” for charging to begin. Once these units begin charging, they may be  
turned “off”. Verify unit battery switch is in NiMH position.  
The LCD on the product goes dark during charging.  
This is normal, discoloration of the LCD may occur during charging. This does not affect the  
performance of the product, and the LCD will return to normal after charging is complete.  
The product operates for a short amount of time after charging before it needs to be charged again  
(less than 5 hours).  
Verify the batteries are less than 2 years old and have not exceeded 500 charge cycles. Replace  
the batteries if necessary. Verify the units receive proper amount of charging time between each  
use. A complete charge takes 14 hours. Listen recommends charging products overnight for best  
performance.
