WARNING
Do not connect the telephone line cord to the
phone socket until your handset is fully charged.
This will prevent the risk of the phone being
answered before the battery is charged.
Answering the phone before the battery is fully
charged may prevent it from reaching its
optimum capacity.
WARNING
Under no circumstances should
non-rechargeable batteries be used. Only use
the approved batteries. Using unapproved
batteries will invalidate your guarantee and
may damage the telephone.
Fully discharging the batteries at least
once a week will help them to last as long as
possible. However, the charge capacity of
rechargeable batteries will reduce with time
as they wear out, so reducing the talk/standby
time of the handset. Eventually they will need
to be replaced. New batteries can be obtained
from the Helpline on
0870 240 4682
.
When the battery has been charged for
at least
16 hours
the display will show the symbol;
you can then connect the telephone line cord to
the base.

If the handset battery symbol is empty and you
hear warning beeps, you will need to recharge
your handset before you can use it.
