3.1.3. Recharge procedure
This equipment has an internal battery charger with a smart circuit which
adjusts the battery charge to the optimized parameters to ensure the
maximum service life. To recharge the battery:
•
Check if the
TM-25R
is off, and then connect it to the 110 V or 220 V
mains supply (using the AC Adapter).
•
The charging indicator (led over key
) will turn on red and will remain
that way until the battery is totally charged. Then the light will remain
green and keep in that way until the
TM-25R
is disconnected of the
mains.
If the equipment is turned on, the charging procedure will be momentarily
interrupted, with the mains supplying the operation of the TM-25R till it is again
turned off.
