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.
