Timer Operations (see pages 20 and 21)
• When you unplug the AC power cord or if a power failure
occurs, the timer will be canceled. You need to set the clock
first, then the timer again.
• Without stopping the recording, you cannot change the source
after Recording Timer starts recording.
• If you set the Sleep Timer after Daily Timer starts playing the
selected source, Daily Timer is canceled.
• If Sleep Timer is set to come on while Recording timer is
operating, Sleep Timer will not come on at all.

Maintenance

To get the best performance of the System, keep your discs,
tapes, and mechanism clean.
Handling discs
• Remove the disc from its case by holding it at the edge while
pressing the center hole lightly.
• Do not touch the shiny surface of the disc, or bend the disc.
• Put the disc back in its case after use to prevent warping.
• Be careful not to scratch the surface of the disc when placing
it back in its case.
• Avoid exposure to direct sunlight, temperature extremes, and
moisture.
To clean the disc:
Wipe the disc with a soft cloth in a straight line from center to
edge.
Handling cassette tapes
• If the tape is loose in its cassette, take up the slack by inserting
a pencil in one of the reels and rotating.
• If the tape is loose, it may get stretched, cut, or caught in the
cassette.
• Be careful not to touch the tape surface.
• Avoid the following places to store the tape—in dusty places,
in direct sunlight or heat, in moist areas, on a TV or speaker,
or near a magnet.
To keep the best recording and playback sound quality:
• Use a cotton swab moistened with alcohol to clean the heads,
capstans, and pinch rollers.
• Use a head demagnetizer (available at electronics and audio
shops) to demagnetize the heads (when the System turned off).
Cleaning the System
• Stains should be wiped off with a soft cloth. If the System is
heavily stained, wipe it with a cloth soaked in water-diluted
neutral detergent and wrung well, then wipe clean with a dry
cloth.
• Since the System may deteriorate in quality, it become
damaged or get its paint peeled off, be careful about the
following:
– DO NOT wipe it with a hard cloth.
– DO NOT wipe it strong.
– DO NOT wipe it with thinner or benzine.
– DO NOT apply any volatile substance such as insecticides
to it.
DO NOT allow any rubber or plastic to remain in contact with
it for a long time.
