Basic Tribune telephones are available in 10 pps pulsing, MF4 signalling and dual signalling models with earth or timed break recall facilities. All models are for table mounted use and are similar in appearance. The facilities offered are as follows:-

MF signalling models (Will be superseded by Dual Signalling models)
Tele 9401AR, MF signalling, earth loop or timed break recall, secrecy button, bell. Normally supplied set for earth recall, may be converted to timed break recall by shifting link accessed via slot in base of telephone.
Tele 9402AR, as 9401AR but with tone caller instead of bell.
Tele 9403AR, as 9401AR but with inductive coupler receiver inset to suit users of certain types of hearing aid.

Dual signalling models
Tele 9801AR, 10 pps or MF4 signalling, earth loop or timed break recall, 31 digit last number redial memory, secrecy, bell. Normally supplied set to 10 pps signalling with earth recall but may be set to MF4 signalling with earth recall or MF4 signalling with timed break recall by adjusting the customer accessible slider switch on the base. When set to 10 pps signalling the telephone offers mixed signalling facilities.
Tele 9802AR, as 9801AR but with tone caller instead of bell.
Tele 9803AR, as 9801AR but with inductive coupler receiver inset.

These telephones all have a REN of 1.

Idle - Normal capacitor loop, additionally Tribunes 99XX & 98XX draw on hook current (typically 20 micro amps) to maintain last number re-dial memory. This may appear to give apparent 'Low Loop' line test conditions.

Seized - Normal off-hook press button telephone loop. The electronic keypad and transmission circuitry may give high resistance tele-loop line test conditions as with other press button telephones.

Bell volume control is achieved by varying the travel of the bell plunger, this can result in bell tinkle due to line disturbances if the volume control is set to 'low'. On certain systems (typically those with electronic ringing generators) a louder ring may be obtained if the control is set at the mid point instead of 'loud'.

Pressing the 'S' button will cut off outgoing transmission on all models without affecting incoming speech except for Tribunes 94XX made by DFM Ltd, on these the level of incoming speech is reduced whilst the 'S' button is held down.

Last number redial memory will be erased on LNR models if the telephone is disconnected from line for typically more than 5 minutes, there is no provision for memory retention batteries.

All Tribunes have good immunity against RFI from 100kHz to 10Mhz.

Telephones 9401AR and 9402AR can be converted to Time Break Recall (TBR).  On the underside of the telephone is a small plug, in a recess, which has makings 'E' and 'T'.  The plug must be removed, turned 180 degrees and replaced so that the raised lug of the plug is now nearest the 'T'.
