Music Disk Recorder; Precautions - Yamaha Electone EL-37 Owner's Manual

6. Music Disk Recorder

The Music Disk Recorder (M.D.R.) is a sophisticated recording device built into the Electone that lets
you record your performances and registration settings. The Music Disk Recorder not only records the
notes you play; it also remembers the voices and rhythms you select, the front panel controls you change,
as well as all expression pedal, footswitch and knee lever positions, to reproduce your performance
exactly as you play it. Moreover, you can separately record different parts of your performance, building
up a song part by part.

Precautions

Be sure to handle floppy disks and treat the disk drive with care. Follow the important precautions below.
Compatible Disk Type
3.5" 2DD and 2HD type floppy disks can be
used. A blank 2DD floppy disk has been
included with your Electone for you to record
your performances.
Inserting/Ejecting Floppy
Disks
To insert a floppy disk into the disk drive:
Hold the disk so that the label of the disk is facing
upward and the sliding shutter is facing forward,
towards the disk insertion slot. Carefully insert the
disk – shutter first – into the slot, slowly pushing it
all the way in until it clicks into place and the eject
button pops out.

Eject button
To eject a floppy disk:
Before ejecting the disk, be sure to confirm
that the M.D.R. is stopped (check if the LED
above the STOP button in the M.D.R.
section is lit and the LED below the disk slot
is off).
Press the eject button slowly as far as it will
go; the disk will automatically pop out.
When the disk is fully ejected, carefully
remove it by hand.
Never attempt to remove the disk or turn
the power off during recording, reading and
playing back. Doing so can damage the disk
and possibly the disk drive.
If the eject button is pressed too quickly, or
if it is not pressed in as far as it will go, the
disk may not eject properly. The eject
button may become stuck in a half-pressed
position with the disk extending from the
drive slot by only a few millimeters. If this
happens, do not attempt to pull out the
partially ejected disk, since using force in
this situation can damage the disk drive
mechanism or the floppy disk. To remove a
partially ejected disk, try pressing the eject
button once again, or push the disk back
into the slot and then repeat the eject
procedure.
Be sure to remove the floppy disk from the
disk drive before turning off the power. A
floppy disk left in the drive for extended
periods can easily pick up dust and dirt that
can cause data read and write errors.
