between 0 and C until the day and time are set.
2. Insert the 2 x AAA NiMH batteries supplied. Then slide
the battery compartment cover into place.
3. Place the handset on the base to charge for at least 16
hours. The red Charging light comes on (the red Charging
light stays on even when the batteries are full charged).
The handset is pre-registered to the base as SYNERGY
HS 1. This is shown on the display. When the handset is
fully charged the display shows a full battery symbol.
4. After 16 hours, plug one end of the telephone line cord
into your BT Synergy 3505 base and the other end into
the telephone wall socket.
Talk/Standby time
Under ideal conditions, fully charged handset batteries
should give about 14 hours talk time or 350 hours
standby time on a single charge.

BT Synergy 3505 – Edition 4 – 11.11.03 – 5675
BATTERY LOW WARNING
If the handset battery symbol is
empty and flashing, and you hear
a warning beep every minute, you
will need to recharge your handset
before you can use it.
Battery performance
To keep your batteries in the best
condition, leave the handset off
the base for a few hours at a time
(after the initial 16 hour charge).
New NiMH batteries do not reach
full capacity until they have been
in normal use for several days.
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, so
reducing the talk/standby time of
the handset. Eventually they will
need to be replaced. New
batteries can be obtained from the
BT Synergy Helpline 0870 605 8047.
Under no circumstances should
non-rechargeable batteries be
used. Use only approved Nickel
Metal Hydride batteries (NiMH)
size AAA capacity 550mAL 1.2V.
Using unapproved batteries will
invalidate your guarantee and may
damage the telephone
