Installation
Battery
The telephone is supplied with environmentally friendly nickel metal hydride
(NiMH) batteries - 2 x AAA 1.2V. As with all batteries, performance may degrade
over time; should you notice that the standby time has reduced considerably or
there are signs of leakage, the batteries should be replaced. Always replace both
batteries using only NiMH rechargeables.
Fully charged batteries will last for approx. 100 hours in standby or approx. 10
hours’ call time. The stated times apply at normal room temperatures using fully
charged batteries.
Completely discharged batteries will take about 10 hours to fully recharge (24
hours from new).
Please note that the battery indicator in the display will flash while the
handset is on the base unit, and does not stop/go out when the battery is fully
charged.
The base unit has an automatic charging mechanism that prevents the batteries
from being overcharged or damaged due to prolonged charging.
Please note!
To ensure and maintain good charging of the handset battery/s we recommend that the base and
handset charge contacts are cleaned regularly, ie monthly, with a pencil eraser and/or a soft dry
cloth.
When the telephone is installed for the first time, the battery pack must be charged for 24 hours
before using the telephone. Use DORO original batteries only. The guarantee does not cover any
damage caused by installing incorrect batteries. The handset is charged with the keypad facing
outwards. Please dispose of any batteries in a responsible and environmentally friendly manner
Battery Charge Indicator
When charging, the status of the battery symbol will remain unchanged until 10
minutes or more continuous charging time has elapsed.
If the batteries are running low will be displayed, although calls can still be
made/received recharging must occur if a warning tone is heard during a call.
Failure to recharge the batteries will result in the telephone ceasing to function.
