First of all, plan your installation and decide where to fit your TDS1. It needs to be
close to a telephone socket, have mains power and an audio signal feed. In
MANual mode, you will be using a telephone to call the listener, so it may be
convenient to install the unit in an ante or side room where no-one will be
disturbed by your conversations. The TDS1 generates virtually no heat and so
can be installed in any dry, convenient location.
Unpack your TDS1 and check the contents against the list above. As supplied,
your TDS1 is set to 100V line input and 3 hour timer enabled.
You will need the following to
Get your TDS1 to work:
Working telephone line
Audio signal

Another telephone eg a mobile to
test operation.
Two small screwdrivers, a posidrive
to remove the lid and a flat blade to

- Page 4 record output, move link J1 to J2 (this disables the attenuator). AUTOmatic Mode Switch the TDS1 to AUTOmatic. Dial the TDS1 telephone line from another telephone. The call should be answered immediately, the Active light should illuminate and you should hear the CD playing.
- Page 5 TDS1 Facilities Output The facilities socket is for advanced users who want to extend the capabilities of the TDS1. It enables remote AUTO / MAN switching and allows a remote Active light to be used. The remote light can be very useful to indicate the TDS1 is in use and connected.
- Page 6 TDS1 OPERATION Switch the TDS1 on. Note the green power light illuminates and the Active light flashes, one flash for automatic operation, two flashes for manual. This confirms the microprocessor is running. If a remote indicator is fitted, this flashes in sympathy with the Active light.
- Page 7 with three or four people in it. For larger venues or locations where the volume is not adequate i.e. many miles from the serving telephone exchange, use a handset with jack audio output. This allows connection from the telephone line into a line input (i.e. CD) on a hi-fi system and hence the signal can be adjusted for loudness and quality by using the volume and tone controls.
- Page 8 WARRANTY The TDS1 is guaranteed for a period of 1 year from the date of purchase provided that it has been used in accordance with all these instructions. This warranty specifically does NOT cover damage by lightning or user abuse and is on condition that the unit is returned by prior agreement, to the supplier.
