| The batteries in my DUALphone no longer works |
If the rechargable batteries in your DUALphone are not discharged on a regular basis, the batteries will in time not have enough power when the handset is lifted from the charger unit.

In order to keep the high performance of the rechargeable batteries in the DUALphone 3088 handset, you are advised to discharge the batteries once in a while.
Therefore, we advise you to leave the handset out of the charger unit during the night twice a week.
