The BT Response 1000 is a mains powered, processor controlled answering machine with digital recording of announcement and incoming messages.

It is menu driven from an LCD display accompanied by voice prompts.

Four AA size batteries will retain the memory for up to 72 hours in the event of a power failure.

Response 1000 may be desk or wall mounted.

The Response 1000 facilities are as follows:-

  • LCD display - Displays two different menus; MAIN menu indicating current mode of Response 1000 and SETUP menu to facilitate programming. Both menus are used in conjunction with function keys 1 - 5.
  • Time and day - Response 1000 records the time and day after each message. if time and day is not set, the announcement "the time announcement is off" will be heard at the end of each message and the digital clock will continue to flash.
  • Voice prompts - Helpful voice prompts tell the user how to set up and use the answering machine, whether programming locally or accessing messages remotely.
  • Voice call counter - When PLAY is pressed, the unit announces the number of messages that have been recorded.
  • Programmable timer - The Response 1000 can be set to turn on/off and answer calls at a preset time. Default times are; ON 6.00 pm. OFF 9.00 am. Pressing key 4, TIMER ON/OFF from MAIN menu will toggle between timer on or off and the legend TIMER ON will show on the display if the Response 1000 is set to turn on automatically.
  • Two way record - Response 1000 enables the user to record telephone conversations.
  • Selective save - Digital machines, such as Response 1000 allow individual messages to be saved.
  • Memo record - Allows personal messages to be recorded directly on to the machine. Maximum length 13 minutes.
  • Remote access - Users can interrogate the machine remotely, using a TouchTone telephone or remote controller.
  • Security code - Security code on remote interrogation allows extra control over who has authority to hear any messages recorded.
  • Announcement - Messages, memos and announcement use the same memory area which has a capacity of approximately 13 minutes. The announcement may be of any length but will reduce the amount of time available for messages and memos. A display of the time remaining in memory may be determined by pressing the SELECT buttons simultaneously.
  • Optional memory module - The customer may purchase this module which will increase memory capacity to approximately 27 minutes.
  • Branchphone reset - Will release machine from the line should a parallel telephone handset be lifted. This facility is inhibited for up to 3 seconds when machine first answers, therefore the facility may not always appear to operate.
  • Call Screening - Volume Control must be turned up to listen.
  • Integral phone socket - Does away with need for a phone socket doubler.

Using the Response 1000
Recording the announcement - From SETUP menu (press and release SETUP key): Press and hold down key 1, ANN REC/CHK until voice prompt is heard, "please speak after the tone".

Approval Number of the Response 1000 is S/1000/3/N/502597
Approved as supplied for connection to the Public Switched Telephone Network (PSTN) and PBX 2-wire extensions.
The Response 1000 is not approved for use on shared service lines or as an extension to a payphone. It is not suitable for use on PBX's where manual ringing is applied.

User guide (supplied with the Answering Machine). Response 1000 - TPU 1667 PLANNING
A Phone Socket and a 240 volts, 13 amp, 50 Hertz mains supply are required within 2.5 metres of the Response 1000.

The Response 1000 is suitable for use on Phone Socket installations on DELs and most types of PBX extensions that provide automatic ringing. The Response 1000 has a Ringer Equivalence Number (REN) of 1 and is intended for use in normal Domestic, Residential or Business locations. They are not suited for use in bathrooms or other locations prone to damp or condensation.

Approximate overall dimensions are:-
(W x L x H, mm) 150 x 200 x 50: Weight, less than 1 kilogram.

The machine contains no on-site serviceable parts, therefore maintenance is limited to functional testing, checking the output of the plug-top transformer, that the line and telephone cords are correctly positioned, (see User Guide), and that the facilities are set for optimum performance of the machine to match the line to which it is connected.

If the machine has failed completely, the output voltage of the Transformer should be checked. The output is marked 9v AC, but will measure about 12 volts when tested with the output open circuit. The Response 20 and Response 50 use the same transformer.

New units carry a 21 month warranty from the date of manufacture, identified by the first 4 digits YY WW **** (Year and Week) of the serial number marked on the underside of the machine.

On-site maintenance of the Response range is limited as the equipment contains no serviceable parts. Some routine servicing - detailed in the User Guide should be carried out by the customer, but field maintenance is restricted to checking the facility switch settings and testing the power unit output.

Several adapters used with Response instruments are marked with lower outputs than those actually measured. Approximate voltage readings (with the output open circuit) are as follows:-
Transformer 19B (marked 13.5V DC) measures 19 - 20v.
Transformer 752 (marked 9V AC) measures 11 - 12v.
Transformer 753 (marked 9.5V DC) measures 13 - 14v.

It has been reported that a large quantity of the Response range of TARMs have been returned as faulty without being fully reset and retried. Some faults are caused by quick line disconnects and Radio Frequency Interference and may be cleared by a reset.

Models such as the Response 200, 300, 400, 500 & 1000 have all got a reset button on the underside of the unit. Depressing this button momentarily, using a small probe, will perform a slightly different reset to that performed when the mains is turned off/on. It is suggested that this is performed first, then retry all facilities, before changing out the unit.

However, if after changing the unit the same fault recurs on the new unit, the problem may be site specific and changing the unit again will be of no advantage. If this is the case, please contact the Technical Helpdesk for further advise.

A major problem with Response TARMs recording after a message has been left has been caused by the exchange equipment presenting ‘clicks’ on the line when it is idle. This is due to a modified line card on System X exchanges. BT Labs are aware of the problem and are investigating a cure. Changing the unit will not clear this problem.
