3 Connect the power
supply unit to a
power socket
Note
Do not connect the telephone line
cord to the phone socket until the
handset is fully charged. This will
prevent the risk of the phone being
answered before the batteries are
charged, which may prevent them
from reaching maximum capacity.
Note
When fully charged and in good
condition, the handset will provide
up to 7 hours continuous talktime
or 72 hours standby.
If the handset battery is running
low, the
IN USE/BATTERY LOW
light will flash every 10-15 seconds.
If you are making a call and the
handset battery is running low you
will hear a warning tone every
10-15 seconds.
Place the handset on the base unit
to recharge.
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 BT shop or from the Helpline
0845 769 7146.
To get the longest possible life
from your battery, take the handset
off the base unit for a few hours
each day.
4 Charge the handset
Before you first use your Quartet
1500, the rechargeable battery in the
handset needs charging for 24 hours.
Place the handset on the base unit,
ensuring the contacts are touching.
The red CHARGING light will come
on.
The charging light will remain
constantly lit while the handset is
placed on the base unit, even when the
handset batteries are fully charged.
There will be a voice prompt
announcing the default settings when
the unit is first switched on.
The power supply unit must remain
plugged in and switched on all the time.
