CASSETTE OPERATING INSTRUCTIONS FOR
YOUR COMPUTER

Important information about your cassette unit

The COMMODORE C2N cassette unit is supplied with a cord
attached. This cord connects the cassette unit to the computer. Power is
supplied from the computer to the unit through this cord. The computer
and the cassette communicate through the cord as well.

TURN OFF THE COMPUTER BEFORE CONNECTING THE
CASSETTE UNIT TO IT.

For VIC computer users

The cassette unit plugs on to a connector at the back of the
computer. See the figure below. The plug will only fit on the connector on
e way. DO NOT FORCE IT.

It is also important to keep the cassette unit at least 2 feet away
from the TV as radio emissions from the TV can interfere with the correct
operation of the cassette unit.

FOR CBM/PET COMPUTER USERS

For CBM/PET computers, 4000 and 8000, the cassette unit plugs
on to a connector at the back of the computer.

PRELIMINARY CHECKOUT

Before using your cassette drive unit to recall or store programs,
you should complete the preliminary checks—which are described below:

STEP 1 Turn off the computer and plug in the cassette unit.

STEP 2 Ensure that the cassette deck motor is off by checking that all of

the function keys are up. If any are not, press the STOP/EJECT
button.

STEP 3 Turn the computer on.

STEP 4 Press the PLAY button on the cassette unit. Look to see that, as
the button is engaged, the READ/WRITE heads move towards
the spindles and the capstan comes into contact with the pinch
roller (see Fig. 1). The take-up spindle should be moving
smoothly in a counter-clockwise direction.

STEP 5 Now press the STOP button. The heads should move back and
the spindle stop.

STEP 6 Press the REWIND button. The tape heads should remain in the
inactive position and the supply spindle should move rapidly
clockwise.

STEP 7 Press STOP again and then F.FWD. The tape heads should still
remain in the inactive position and the take-up spindle should
move rapidly counter-clockwise.

STEP 8 Press STOP once more and then GENTLY attempt to press
REC. You should feel strong mechanism resistance.

STEP 9 If all has worked properly, proceed to the operations test on the
next page. If you have encountered any difficulties with the
preliminary checkout, please turn to the last page in this manual.
