Troubleshooting Guide - Onkyo MD-185X Instruction Manual

Troubleshooting guide

If you encounter a difficulty while using your unit, use this troubleshooting guide as an aid to remedy the problem. Because the unit
contains a microcomputer to provide advanced functions, it may malfunction due to external noise or static electricity. If this happens,
disconnect the power cord and then plug it in again after about 5 seconds. You must also be sure that the system components are properly
connected.
If the MD recorder still does not operate correctly, disconnect the power plug, then plug it in again while pressing EDIT/NO button and
YES button simultaneously.
Note that any TOC information held in this MD recorder will be erased by this operation.
If the problem persists even after you try this remedy, or it is not listed in the table, disconnect the power cord and then consult the shop
from which you purchased the unit or your nearest ONKYO service station, informing them of your name, address, phone number, type
of unit, and the details of the problem.
• The unit does not operate or operates poorly.
Cause: The disc may be damaged ("Disc Error" appears).
Remedy: Take the disc out and insert it again. If "Disk
Error" remains, replace the disc. (See page 32
"Precautions for handling the MiniDisc (MD)")
• The unit does not play.
Cause: Moisture has formed inside the unit.
Remedy: Take the MD out and leave the unit in a warm
place for several hours until the moisture
evaporates (See page 33).
Cause: The unit is not on.
Remedy: Insert the AC power cord (main lead) plug into
the wall outlet (the mains) securely.
Cause: The disc is inserted in the wrong direction.
Remedy: Slide the MD into the disc compartment with
the label side up and the arrow pointing toward
the opening until the unit grips it (See page 10).
Cause: The disc may not be recorded (the track numbers do
not appear).
Remedy: Replace the disc with one that has been
recorded.
• The sound has a lot of static.
Cause: Strong magnetism from a television or a similar
device is interfering with operations.
Remedy: Move the unit away from the source of strong
magnetism.
Condensation
This is the same phenomena that causes windows to become
misted up with water drops in a heated room during the winter.
The MD recorder also sometimes gets dew (water drops) on the
optical lens inside the player under the following conditions.
• Immediately after you turn a heater on.
• If the MD recorder is placed in a room with full of steam or
dampness.
• If you suddenly bring the MD recorder in from the cold
outside into a warm room.
• The unit does not record.
Cause: The disc is record-protected ("Protected" appears).
Remedy: Close the record-protect slot (See page 23).
Cause: The unit is not connected properly to the sound
source.
Remedy: Make connections properly to the sound source.
Cause: The analog recording level is too low.
Remedy: Turn the REC LEVEL control knob to adjust
the recording level properly.
Cause: A premastered disc is inserted.
Remedy: Replace it with a recordable disc.
Cause: There is not enough time left on the disc.
Remedy: Replace it with another recordable disc with
fewer recorded tracks.
Cause: There has been a power failure or the power cord has
been disconnected.
Remedy: The contents of the recording may be lost
permanently. After connecting the power cord
or immediately after power has been restored,
the STAND-BY/ON button. (See page
23"Storage Period of Backup Data".)
Cause: An attempt was made to record from a digital input
source, but it is not connected by the optical cable
("D. In Unlock" appears).
Remedy: Connect the digital input source by the optical
cable or set the INPUT button to "Analog In".
• The disc name or track name cannot be entered.
Cause: The disc is record-protected ("Protected" appears).
Remedy: Close the record-protect slot (See page 23).
Cause: A premastered (read-only) disc is inserted
("Cannot Rec" appears).
Remedy: Replace it with a recordable disc.
If the unit does not operate properly even after attempting the
prescribed remedies, unplug and then plug in the power cord
again.
If the MD recorder is exposed to dew condensation
You can leave it as it is. Sometimes the recorder cannot read the
signal sent from the disc by laser and the recorder doesn't work.
Depending on the surrounding conditions you can remove the
disc and leave the power on for at the longest one hour. The
dew will evaporate and the recorder will work properly. If it
doesn't work after several hours, please consult the nearest
ONKYO authorized service center.
