This circular introduces the KIRK Loudspeaking Telephone (LST No. 10) which is a
proprietary loudspeaking telephone purchased from a continental manufacturer as a stop-gap
measure until ACCORD (LST No. 8) is available later this year.
KIRK will initially undergo Product Trial in LTR West and SIB Aberdeen Telephone Areas
during April 1981. The trial will be for a limited period of one month, held during May
1981. Areas will be advised, by telex, of national availability, but see Marketing Policy.
DESCRIPTION AND FIELD OF USE
KIRK is a voice switched loudspeaking telephone of modern design with a dark grey base,
press-button keypad, and a choice of coloured case covers. The handset is two-tone, dark
grey base and coloured top matching the case cover. Colours available are Brown, White,
Green, Yellow, Orange and Lava (Fawn).
On hook dialling, i.e. the ability to dial without lifting the handset, is available by
using the control buttons.
KIRK is available with either a self-contained or HP keypad, and as such may be used on
direct exchange lines and PBX direct extensions only. KIRK is not suitable for Plan
The incoming speech level received on both the handset and Loudspeaker is variable, by
using the volume control on the handset.
KIRK has an electronic tone caller which may be set to one of 4 tone options by the
customer, using a small coin, and is line powered with a 2 metre line cord.
Separate instructions have been sent to the Product Trial Areas.
KIRK is intended solely as an interim instrument to help overcome the current stock
shortages of LST 4E and LST 4MF which have been aggravated by manufacturing delays of
ACCORD (LST 8). The ASCO will advise the S Division of the customers who have been waiting
stores for LST 4E and LST SA 4265 from outstanding requisitions. On receipt of this
advice, S Divisions will offer a KIRK to these customers in lieu of the LST 4, if required
on a direct exchange line or direct PBX extension. If the offer is accepted by customer,
the AN can be issued.
In view of the limited quantities purchased, KIRK must not be actively sold, customers
requiring LST facilities should be offered LSTs 4D, Doric or Harmony (after June 1981) to
fulfil their needs. New requests for MF LSTs should not be met by KIRK. Under no
circumstances will KIRK be permitted on Service lines.
If the market reaction to KIRK is encouraging and the product trial successful every
effort will be made to purchase further quantities, UK produced, towards the end of 1981.
A dual purpose leaflet/operating instructions is available. Copies will be packed with
each KIRK and should be left with the customer at the time of installation. Additional
copies will be available in the usual way from Swindon Stationery Depot.

The Kirk originated in Denmark in 1976 and because of it's unusual design has gained
international attention and recognition. This telephone was designed by the industrial designer
Jacob Jensen who also designed Bang & Olufsen's
famous radio and TV products.
In 1972 the Jutland Telephone Company Ltd. (Jydsk Telefon) began development
of this telephone. They did not base the development on earlier technologies or
models, as electronics was replacing former electromechanical
parts. An example of this is that the telephone bell has been replaced
by an electronic tone ringer whose sound is reproduced by a
loudspeaker. The loudspeaker is also used for handsfree conversation.
This telephone has been a big export product for Denmark and is manufactured under
licence in several countries.
