6 Quick set-up guide
Battery performance
• To keep the batteries in the
best condition, leave the
handset off the base for a
few hours at a time.
• After charging your handset
for the first time, subsequent
charging time for the
batteries is approximately
6-8 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
218 2182*.
Set up your additional handsets (multipacks only)
1. For additional handsets and chargers: plug the
mains power adaptor into the back of the charger
and plug the other end into the mains wall socket
and switch on the power.
2. Activate the batteries as explained on page 5.
3. Place the handset on the charger to charge for
24 hours.
If you ever need to remove the batteries, simply
slide open the battery compartment cover and
ease out the batteries.
