When a "0" is applied to pins 1 of these connectors, the internal clock
is blocked and the relevant input/output devices are blocked. As the
levels of these AROFLEX signals must be adapted to the levels in the
fast tape equipment, adaptors are needed to suit the type of fast tape
equipment employed. Tape equipment for up to 900 bauds can be used.
1. Insert the plugs of both tape machines into the mains supply sockets.
2. Push the OFF-LINE button and the PROCEDURE button; make sure
that the INDIRECT button is released.

partment on the keyboard; type the station identification and
serial number and one Carriage Return.

4. Select the required baud speed on the adaptor, switch on the tape
punch, wait till the "ready" signal is lit, and type the required
clear text heading (Format Lines 1 ... 11) on the keyboard or use
a previously prepared tape. This heading is not printed but is punched
on the fast punch.
