TROUBLESHOOTING

If this unit doesn't work properly, the reason will probably be that a small mistake was made in carrying out the

operations given in this manual. Before calling for repairs, check the following.

Problem

Sound cannot be recorded onto a

track.

The sound of an instrument

connected to one of the input jacks or
the tape playback sound cannot be
listened to or recorded.

The level at high frequency drops
during playback.
The playback level is too low.

Excessive distortion and noise are
heard during playback.

When an instrument is connected and
played, the level meter does not rise
to the proper level even though the
channel fader is set to "10".

The unit does not operate when the

POWER switch is turned on.

Signals are not properly synchronized
during SYNC recording.

Probable Cause

The REC SELECT switch is set
incorrectly.

The setting of the ASSIGN switch(es) is
incorrect.

The corresponding input selector switch

is set incorrectly.

The record/playback head is dirty.

The recording level is set unproperly.

The tape is set incorrectly.

The output level of the connected

instrument is too low.

The power cord is not plugged
incorrectly.

The SYNC switch is not pressed to be
turned on.

The level of the already-recorded FSK
signals is too low.

The level of the signals to be recorded
on track 7 is too high.

Remedy

Set the REC SELECT switch correctly.

Select "ODD" for odd-numbered tracks (1,3,5,7) to be
recorded and "EVEN' for even-numbered tracks (2,4,6,8).

Set the input selector switch to the correct position.

Clean and demagnetize the head.
Refer to "Maintenance" described below.

In recording, set the recording level properly while watching

the level meter.

Reset the tape correctly.

Increase the output level of the instrument, or adjust the
GAIN control for the channel which the instrument is

connected to.

Plug the power cord correctly into the mains power supply

or into the unit.

Press the SYNC switch to be turned on, and the FSK

signals should be recorded onto track 8.

Re-record the FSK signals.

Reduce the level of the signals or record the signals onto

another track.
