Warning Warning
Do not use the battery reconditioner in the patient vicinity.
Be sure there is no contact between the patient and the charger, including no contact
from the charger to a medical care giver to the patient.
The Battery Reconditioner can be used for charging or reconditioning the TeleMon battery.
During normal operating conditions, the battery is recharged while TeleMon is connected to
an AC power source. However, over time the battery loses its ability to fully charge. When
the battery's capacity changes by 10% from the last time it was reconditioned, a microchip
inside the battery indicates that it needs reconditioning to optimize performance.
During the reconditioning process, the battery is discharged, charged, discharged again, and
then charged again.
The following table lists the definition for each LED state on the reconditioner.

second time to reset its internal settings; finally to get it ready for use, it's recharged.
