Additional Information

General
Introduced in 1981 the press button, Ambassador Telephones were supplied in two different ranges:-
Ambassador Mk 1 (Telephone 8200R, 8202R (developed version) and 8220R press button - 10pps signalling and (8300R MF4 signalling) with 700 type telephone circuitry.  Telephone No. 8220R has a 10 address memory.

Ambassador MK2 (Telephone 8204R press button 10pps signalling and 8304R MF4 signalling) with 'Statesman' type telephone circuitry.  Ambassador MK2 was marketed as 'Ambassador 2'.

Both Mark numbers are externally similar but are internally quite different.

Mk 1 telephones had a Handset No. 16A, identifiable by the earpiece having only three holes in a recess (shown to the right).  The Mk 2 (developed version) can be identified by the 'banana' insert in the right hand side of the case.  This was to allow the fitting of add-on units (amplifiers etc).

Only the Mk2 can be wall mounted.

Certain Ambassador MK1 models were available to make up 'Ambassador Plus' telephones (by the addition of Facility Handsets) primarily to help meet the needs of some disabled customers.  Mk1 telephones were retained as a stores item without the handset. 

Incoming calls on all Ambassador telephones are signalled by a bell with a bell off facility, on most models there is also a degree of bell volume control.

TESTING
Idle - Normal capacitor loop.
Seized - Normal Press Button Telephone loop.  The diode bridge in the keypad may give high resistance loop test conditions when tested with low voltage testing equipment.

NB: Telephone No. 8220R contain a line-charged battery, which will charge from line at 1mA provided line voltage is not less than 22 volts, continuous charging is not necessary.  Telephones of GEC (GEN) manufacture require a Battery Dry No. 102 whilst telephones of TMC (GNA) manufacture require a Battery Dry No 33.

The battery is charged from line by a charge switching circuit that disconnects the battery for approximately 30 seconds whenever line conditions are disturbed, e.g. during line testing.

Facility handsets are as follows:-
Handset No. 16C, incorporates a line powered amplifier to increase the volume of incoming speech signals, also includes an 'inductive coupler' receiver inset 2/3T to benefit users of 'inductive coupler' hearing aids.
Handset No. 16D, incorporates a neon indicator that lights up to incoming ringing signals.
Handset No. 16E, incorporates a microphone cut-off switch this is normally `non-locking' but may be made `locking' by removing the switch slider and turning through 180 degrees.
