TRIMPHONE Sales Circular

TRIMPHONE

1. Marketing Policy
A&PRD Circular 342/65 introduced Trimphone in several selected Areas some of which were asked to stimulate sales. The present level of supplies and estimated size of the market now enables spontaneous orders to be accepted. nationally and, the active campaign ho ha extended to all areas in LTR (London Telephone Region).  Stimulated selling will also continue in Wales and. Border Counties and. Northern Ireland.

2. Description
The Trimphone is a light weight table instrument weighing only 2lbs, It is 8,25" long, 4.25" wide and 4.25" high.
Colours are as follows:

In place of the conventional bell the Trimphone has a tone caller, a built-in electronic device which produces a high  pitched intermittent warbling note, The tone caller has a three position switch which allows the tone to be varied from soft to loud. In the build-up position (marked >) the tone starts quietly and. builds up to loud in about 10 seconds. Where required the switch can be arrange to provide an 'off' position f or plan arrangements etc. The dial has a transparent finger plate with letters and figures beneath the finger holes and is permanently illuminated from within by a self energised fluorescent tube which does not require a power supply. The level of illumination is adequate to make the dial easily visible in a darkened room. Other features of the Trimphone are its lightweight handset which rests over the dial, the handset rest which forms a carrying handle, and the instrument cord which extends from 4' 6" to 9'. A photograph of the instrument is at Appendix the design and colours have been approved by the Council of Industrial Design.
