This TI describes the Auralite Headset (Headset 3) and the Auralite Executive Headset (Headset 3A).

Maintenance procedures are described in TI E5 B5320.

The Auralite Headsets may be used on any installation where the Headset No. 1 can be used, i.e. as an operators' instrument on the larger PBXS, in addition to, or in lieu of, the operators' handset or telephone on small switchboards, key and lamp units and telephone instruments on exchange lines, extensions and private circuits and in any operational situation where a 'hands free' telephone facility is required.

The Auralite Headset (Headset 3) weighs 30 g (1 oz) and does not need a headband but rests lightly on either ear; alternatively it can be attached to spectacle frames using the clip provided (Clip No. 104A). The voice tube is adjustable and the plastic hearing tube is connected to an ear tip which rests just inside the ear. Six different size ear tips are provided with each Headset to allow individual fitting. A 3 metre (part helical) cord connects the Headset to a 4 way jack plug and a small amplifier is fitted in the cord close to the jack plug. Also, an adjustable clothes clip (Clip 103A) is provided on the cord for optional use with or without a lanyard.

The Headsets and all accessories are provided in a personal pouch for easy storage.

The Auralite Executive Headset (Headset No. 3A) is the same as the Auralite Headset but a quick release plug incorporated in the cord which gives the user greater mobility as the Headset can be disconnected without losing a call in progress.

No special requirements for installation of the Auralite Headsets.

When the Auralite Headset is requisitioned a set of six different ear tips are included (Earpiece Set No. 1A). Additional earpieces are available once a suitable size has been decided upon. The earpieces are requisitioned as Earpiece 28 A/1 .... A/6, depending on the size required, and are supplied in packs of five.

Additional parts available:-
Pouch 2A
Clip No. 104A (Spectacle clip) Clip No. 103A (Clothing clip) Lanyard No. 2A
Tube Voice 1A.

The headset should be recovered and booked into the stores as Headset 3 or Headset 3A.

Additional information

The Headset No. 3 is an ultra lightweight headset which rests lightly on the ear or it may be clipped to a spectacle frame. The voice tube is adjustable and a plastic tube from the receiver connects to an ear tip which rests just inside the ear.

These headsets are no longer available for new supply and are being superseded by the following items.

Headsets No. 3A (Auralite Executive) only differ from Headsets No. 3 by the addition of a quick release jack in the headset cord. The quick release jack enables users to disconnect the headset at the jack without losing the call.
