If you experience any problems, please call the Helpline on 0870 605 8047 or email bt.helpdesk@suncorptech.com
Charge the handset
1. Rechargeable batteries are already fitted in your
handset. To activate the batteries, pull the plastic tab
away from the bottom of the handset as shown.
2. Place the handset on the charger to charge for at least 24
hours. The red Charging light comes on (this will stay on
even when the batteries are fully charged). When the
handset is fully charged the display shows the symbol.
Registering your handset to either your BT Synergy
4100 or 4500 base
If you are registering the handset to another DECT GAP
compatible base station that is not a BT Synergy 4100 or
4500, please refer to the user guide for that base for
registration instructions.
Before registration, make sure the handset batteries are
fully charged and that you are close to the main base
station.

Talk/Standby time
In ideal conditions, fully charged
handset batteries should give
about 10 hours talk time or 100
hours standby time on a single
charge. The base must remain
plugged in to the mains and
switched on at all times.
Note that new batteries do not
reach full capacity until they have
been in normal use for several
days.
Battery low warning
If the symbol flashes in the
display and you hear a warning
beep every 10-15 seconds, you
will need to recharge the handset
before you can use it again.
During charging, the symbol
will scroll in the display.
Battery performance
To keep your 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.
The charge capacity of
rechargeable batteries will reduce
with time as they wear out, giving
the handset less talk/standby time.
Eventually they will need to be
replaced. New batteries are
available from the BT Synergy
4000 Helpline on 0870 605 8047.
