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.
