| Table Telephone (1000 Type) Automatic This telephone, known as "1000 type" because of the suitability for lines
of up to 1000 ohms loop resistance. This model has provision for 1 button. SINGLE COLOUR TELEPHONES
DUAL COLOUR TELEPHONES
High transmission efficiency is achieved by using a new type handset containing a rocking-armature receiver in conjunction with a closed-iron-circuit type of anti-side-tone induction coil. The handset has a more hygienic mouthpiece than those of earlier types and is shaped for maximum comfort and clarity of speech. Through ventilation of the telephone is provided via gauze-screened metal ventilation cups inserted one on each side of the case. These cups are also useful as finger grips when lifting the instrument and are coloured to match the handset. The internal apparatus is mounted on the metal base which has rubber feet and is secured by four captive screws to the case. Removal of the case allows access to all parts for maintenance. Cradle-switch springs are operated by twin plungers bearing on rollers attached to a hinged plate. The trigger dial of the auto set has standard numbering and impulse ratios unless otherwise ordered. Desk and handset cords enter the case via a rubber protector. They have p.v.c. insulated conductors and a close braided cover. All connecting wires are p.v.c. insulated. Line connections are made at screw terminals in a moulded desk terminal block of the same colour as the telephone case.
