THQ CIRCULAR

S1 B8118, April 1981

INTRODUCTION
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 extensions.

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.

PRODUCT TRIAL
Separate instructions have been sent to the Product Trial Areas.

MARKETING POLICY
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.

Push-button telephone 76E/DK80

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.
