Battery; The Display - Doro 640r Manual

Battery

Because batteries only have a certain lifespan it is quite normal that call time and standby time
will decrease somewhat compared to the specifications when the telephone is used regularly.
Batteries (750 mAh) that have been fully charged (10 hours) will last for approx. 120 hours in
standby or approx. 12 hours call time. These operation times apply at normal room temperature.
Full battery capacity will not be reached until the batteries have been charged 4-5 times.
The base unit has an automatic charging mechanism that prevents the batteries from being
overcharged or damaged due to prolonged charging.
Please note!
The charging connections should be cleaned regularly with a soft cloth and/or an eraser.
The base unit should not be located close to other electrical equipment, in direct sunlight or near any other strong
heat source! This is to minimize the risk of interference.
It is normal for the device to become warm during charging and is not dangerous.
Use only DORO original batteries. The guarantee does not cover any damage caused by incorrect batteries.
