APPROVAL STATUS
Approval Number S/1010/3/N/502566
Approved as supplied for connection to Public Switched Telephone Networks (PSTN) and
2-wire PBX extensions. It must not be connected to shared service lines or used as an
extension to a payphone.
DOCUMENTATION
A User Operating Guide TPU 1783 is supplied with each machine.

PLANNING
A Phone Socket and a 240 volts, 13 amp, 50 Hertz mains supply socket are required within
easy reach of the line cord (2700mm) and mains flex (2400MM).
Response 80 is suitable for use on Phone Socket installations on DELs and most types of
PBX extensions. Not suitable for use on "C" wire PMBXS.
Ringer Equivalence Number (REN) is 1.
INSTALLATION/COMMISSIONING
Install and commission the machine as detailed in the User Guide.
MAINTENANCE
The machine contains no on-site serviceable parts, therefore maintenance is limited to
functional testing, checking that the line cords and facility switches are correctly
positioned, the customer has cleaned the tape heads and checking the condition of both the
tapes.
If the machine fails completely the output voltage of the Transformer 19B should be
checked. The Transformer 19B output is marked 13.5 volts DC, but will measure about 20
volts when tested with the output open circuit.
Faulty transformers and machines should be replaced by a maintenance spare and the
recovered item returned to BT stores in the replacement items packing. A completed fault
report form A8807 should be included describing the fault symptoms.
ROUTINE MAINTENANCE
The user guide recommends that the customer should turn over both tapes after six months
and change both tape cassettes at yearly intervals. Cleaning of the tape heads, capstan
and pinch wheel should be carried out at six monthly intervals with a cotton bud dampened
with a proprietary tape head cleaning fluid.
WARRANTY
New units carry a 21 month warranty from the date of manufacture as shown on the year and
month marking on the base of the machine. The year and month marking forms part of the
machine serial number as follows:-
Serial No. 2IBHA001024:-
Indicates:- 2 is the year. 0 = 1990, 1 1991, 2 = 1992 etc
I is the month I = Sep, L Dec, A = Jan etc
B is days in month. A = 1 to 10, B = 11 to 20 and C = 21 to 31.
HA001024 is the machine serial number.

ADDITIONAL INFORMATION
1. REMOTE INTERROGATION
Response 80 provides the facility for remote interrogation using a customer programmable
security code. The code may be set by pressing PROGRAM, you are then prompted to enter
your code. Pressing the REW or FF keys allows selection of the new code. Press PROGRAM
again to store selection.
Remote interrogation is achieved by using a BT Remote Interrogator or MF4 telephone. Enter
the two security digits during the announcement, and follow prompts. A full description is
contained within the user guide.
2. PSU OUTPUT VOLTAGES
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.
KNOWN ISSUES
ACTION BEFORE CHANGEOUT (July 1994)
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.
RESPONSE RANGE: NOT CLEARING AFTER CALL (July 1994)
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.
