The original Viscount telephones are either Pulse dialling or MF dialling and
earth recall. Later variants suffixed with the letters "AR" (Alternative
Recall) supported Pulse dialling / MF dialling and Earth recall / Time break
recall, which was configured by switches on the base of the telephone.
The recall button is located under the handset, just above the dial label.
The ringer volume is adjusted by a lever under the telephone.
The dial label cover is easily removed by pushing the cover to the left.
These telephones could be wall mounted with an optional wall bracket.
The wall brackets colour matched the telephones.
Made by STC Telecommunications Ltd they were introduced 1982 and production ceased in the early 1990's.

Additional Information
Ringer
Incoming calls are signalled by a tone caller, that has an adjustable volume control,
beneath the right hand side of the instrument.
Telephone No's 9501, 9511 and 9601 each have a Ringer Equivalence Number (REN) of 1. Telephone
instruments (BT and non BT supplied) are now required to be labelled with their REN so
that users do not exceed the permitted maximum number of ringers in circuit.
A telephone with a REN of 1 has a ringer sensitivity similar to that of a standard
instrument (Telephone No. 8746G), the total REN value of all ringers connected at any time at an
installation must not exceed 4.
The REN does not guarantee compatibility between ringers of different technologies on the
same installation.

Power Requirements
Telephone No's 9501, 9511 and 9601 are 50 volt line powered instruments and require no external
power supplies. The Telephone No. 9511 last number re-dial facility constantly draws
a small current from exchange line to maintain the memory, if the instrument is disconnected from
the line for
more than a few minutes the memory will be erased.
Wall Bracket
These
wall brackets were an optional extra and came in the same colours as the
telephone.
A plastic peg is supplied with the telephone, this should be
fitted to the gravity switch plunger to prevent the handset from falling off the
cradle when the instrument is wall-mounted. The peg is fitted by pushing
the two prongs into the holes in the plunger and snapping of the excess lug.
Fitted to the wall with three screws.
To attach the phone - locate the top of the phone to the two
tabs at the top of the bracket and then lower the bottom edge. The bottom
edge of the phone locates on two clips at the bottom of the bracket.
To remove the phone - the bottom of the bracket is squeezed
together which releases the phone.
The two lower arms are available to hang the handset on during a
call and not for wrapping the line cord around like many people did.
