If you cannot get through to a number from any
phone, although you can hear a tone
You should check all other handsets on the same installation are
properly replaced before trying to make a call again.
If your tone caller does not operate
Connect the phone to a socket which you know is working properly
- provided of course, that there is more than one socket on the
installation. If the problem continues your tone caller could be at fault
(but check that the total
REN
value of all the telephones connected
does not exceed four).
Care of your Viscount
We recommend that you clean your Viscount with a damp cloth.
Do not spray aerosol polishes into any of the openings or vents and
avoid the use of abrasive cleaners as these will damage the phones
finish.
To preserve the appearance of the exterior finish, avoid placingithe
telephone in direct sunlight.
Since your telephone is an electrical device you should avoid using
it near a bath.
The coiled handset cord will remain in good condition if care is
taken to ensure that it does not twist or knot.
Maintenance of your Viscount
When you buy your Viscount it has a one year guarantee. Should a
fault occur during this time it will be necessary to return it to the place
of purchase. Alternatively to avoid the need for this you may wish to
consider taking out the optional special maintenance and repair
service contract with British Telecom from the date of purchase. For
more details of this service contract, contact your local British
Telecom Sales Office or the shop where you bought your telephone.
Please do not try to adjust or repair a phone yourself. T here is no
part of your phone that you could possibly service, and anything you
might try to do could make any problem worse and invalidate your
guarantee.
Always remember that unless you have taken out an Optional
Service Contract after buying your Viscount, British Telecom will
charge a fee if an engineer visits your home.
Maintenance of your Viscount telephone when
connected to a private branch exchange
When the telephone is connected to a PBX by the st:indard plug
and socket, maintenance may be carried out by any person so long as
the telephone is unplugged before maintenance activity commences.
However, if the telephone is repaired by anyone other than British
Telecom, its staff or its agents, the British Telecom guarantee will of
course no longer be valid.
