The BT Relate 2000 is a highly featured PSTN Videophone which can send a video image of the caller over the PSTN to another Videophone. The Relate 2000 is also compatible with audio only telephones. The Relate 2000 can be wall or table mounted and has the following facilities:

Twelve alpha-numeric keys, (0 to 9, * and #), Seven function keys and eight video control keys. A shift key, used in conjunction with some of the keys, gives added facilities. In common with the Relate range, the dialling keys are lettered and numbered.

Tone caller
Incoming calls are signalled by a tone caller which has an adjustable volume control on the underside of the telephone with HI, LO and OFF settings. The tone and frequency can also be set through software control.

Pressing the SECRECY button will cut off sound transmission in audio mode, or sound and video transmission in video mode without affecting incoming speech or video. It can be used in handset or loudspeaking mode. Press Secrecy button again to reinstate transmission. An indicator will light when secrecy is in use. Secrecy is automatically switched off when a call is completed, but is not affected when switching between video and audio operation.

Allows a pause of 3.4 seconds, with a maximum of three pauses to be inserted in a stored number. This is required by some PABXS.

Memory Store
Up to 10 numbers of up to 20 digits long may be stored. These numbers and redial are stored in EEPROM and will be retained, without power source, for up to five years.

Memory recall
Operation of this key, followed by the memory number, will call the stored number.

Timed Break or Earth Loop Recall.

With the handset lifted, or in loudspeaking mode, pressing the REDIAL button will cause the last number dialled to be repeated.

Allows full handsfree operation. The indicator adjacent to the key will light when loudspeaking is in use.

This key, mounted under the hinged video unit, displays the time since handset lifted. Incoming and outgoing calls can be timed, in hours and minutes. If no call is in progress, the time displayed will be the last call made. The timer will only operate when connected to the mains power supply.

Colour Liquid Crystal Display.

The LCD is a 2.9" screen which displays the incoming video signal at a rate of 8 frames per second. If the picture is unclear due to line noise or other interference, the rate may be slowed to 3 - 4 frames per second.

Video On/Off
The call will be established as a voice call. To protect user privacy, video can only be switched on by mutual consent with both parties having agreed to a video connection and having compatible video telephones. The Video On/Off keys of each telephone must be pressed within five seconds of each other. Whilst the link is being made, the screen turns blue and displays "wait"; the line will also appear "dead". Further operation of the key, during video, will remove the video link and restore the call to audio only.

Contrast brightness and colour setting
These keys allow the user to adjust their display for optimum effect. Pressing brightness alters the brightness of local picture and contrast alters contrast of local picture. Colour control does not affect the local picture unless in self view. Colour of the received video signal is controlled by the distant end using shift contrast.

Self view
With a video call in progress, the left hand corner of the screen will display the transmitted picture ("picture in picture" facility). This can be removed by operation of the SELF-VIEW key. SHIFT/SELF-VIEW enables a full picture of the out-going signal to be seen, so that a check of what the distant end is receiving can be made.

Operation of the SHIFT key together with SELF-VIEW allows the user to see a mirror image on the screen. It is recommended that this is used before making a video call. The method by which a mirror image is obtained varies depending upon the mode of operation;

SHIFT/SELF VIEW with handset on hook or in video mode.
SELF VIEW only with handset off hook and no call or voice call only.
Freeze frame
Allows the user to freeze the display at any time during a video call. Further operation unfreezes the display. There is a short delay whilst the picture builds up. During this time WAIT is displayed.

Video refresh
During freeze frame, operation of VIDEO REFRESH will update the screen.

Controlled by a mode switch on the underside of the instrument.
P-E for pulse
T-E for earth loop
T-TB for timed break
