Battery performance
• To keep the batteries in the
best condition, leave the
handset off the base for a
few hours at a time.
• Running the batteries right
down at least once a week
will help them last as long
as possible.
• After charging your handset
for the first time, subsequent
charging time for the
batteries is approximately
8 hours.
• The charge capacity of
rechargeable batteries will go
down over time, which will
reduce the talk and standby
time. Eventually they'll need
replacing. For details on how
to get replacement batteries,
call the helpline on
0800 145 6789*.
Set up your additional handsets
(multipacks only)

underside of the charger, secure the cable behind
the retaining clip and plug the other end into the
wall power socket and switch on.
2. Insert the batteries as shown on page 5.
3. Place the handset on the charger to charge for
16 hours.
