Страница: 52 / 57

Environment
Your BT Quartet 2015 should be kept free of
dust, moisture, high temperature and vibration,
and it should not be exposed to direct sunlight.
It should not be used in bathrooms or near water.
Your Quartet 2015 is designed to be operated in
a normal office or domestic environment only,
where the relative humidity is no more than 60%.
Maintaining your Quartet 2015
Clean with a soft, dry cloth, do not use a damp
cloth.
Do not use abrasive materials, solvents or
aerosol cleaners as these may damage the unit.
Do not place on untreated antique furniture.
How many phones can you have?
Although you may have any number of sockets,
it is important to limit the number of phones and
other pieces of apparatus connected in order to
ensure that each phone will ring.
All telephone equipment has a Ringer
Equivalence Number (REN), which is used to
calculate how many pieces of apparatus may be
connected to any one telephone line.
Telephones provided by BT have a REN of 1,
unless otherwise stated on the underside of the
phone. Even where the number of telephones
has been limited, there is no guarantee that
different types of phone on the same line will
ring, even when the REN is less than 4.
You must not connect more than 4 products to a
single line.
Network connection information
Your Quartet 2015 is designed to work with both
BT and other UK networks, including cable.
Although this equipment can use either Loop
Disconnect (Pulse) or DTMF (Tone) signalling,
the performance of the DTMF (Tone) signalling
is subject to regulatory requirements for correct
operation. It is therefore strongly recommended
that your equipment is set to use DTMF (Tone)
signalling for access to public or private
emergency services.
DTMF signalling also provides faster call set-up.
