If a problem occursIf this product is subjected to strong external interference(mechanical shock, excessive static electricity, abnormalsupply voltage due to lightning, etc.) or if it is operatedincorrectly, it may malfunction or the display may notfunction correctly. If such a problem occurs, do thefollowing:
• Unplug the AC power lead from the AC socket.• Wait about 20 - 30 seconds and then plug the AC power
lead back into the AC socket.• Press the reset key on the back of the unit.
• When the reset key is pressed, all of the settings in memorywill be erased.

Beware of condensationWhen water vapor comes into contact with the surface ofcold material, water drops are produced. If condensationoccurs, correct operation may not be possible, or the unitmay not function correctly.This is not a malfunction, however, and the unit should bedried.(To do this, turn the POWER switch ON and leave the unitas it is for several hours.)
Be especially careful in the following conditions:• When the unit is brought from a cold place to a warm place
and there is a large temperature difference.• When a heater starts operating.• When the unit is brought from an air-conditioned place to
a place of high temperature with high humidity.• When there is a large difference between the internal
temperature of the unit and the ambient temperature, or inconditions where condensation occurs easily.

When MD fails operateIf the objective lens of optical pickup is contaminated, MD may fail to operate. At first, clean the objective lens to check playbackoperation. If MD fails persistently to operate, perform checks as follows.If dust or foreign substance is accumulated on the pickup lens, playback is disturbed and indication of TOC (content of tracks) maybe disabled. Before adjusting check that the lens is clean. If the lens is contaminated, treat it as follows.
Turn off power supply, impregnate the lens cleaning paper with a small quantity of isopropyl alcohol, and gently wipe the lens withit with due care so that the lens is not damaged. At this time do not touch the lens directly with your finger.
