Handling the Discs
1. Always place the disc in the disc tray with the label facing upward.
2. To remove a disc from its storage case, press down on the center of the case and lift the disc out,
holding it carefully by the edges.
3. Finger marks and dust should be carefully wiped off the disc's recorded surface with a soft cloth.
4. Never use such chemicals as record sprays, antistatic sprays or fluid, benzine or thinner to clean
discs. Such chemicals will do irreparable damage to the disc's plastic surface.
5. Do not expose discs to direct sunlight or high humidity and temperature for extended periods.
Long exposure to high temperatures can warp the disc.

to recognize after separating the partition in 40Gb unit and formatting to FAT32. When using an exterior
hard disc, recommend you the product in 3.5 inches that supports its own power supply to the
exterior hard disc.
In case of the product in 2.5 inches, if the power consumption is larger than the supply power,
the recognition doesn't become occasionally.

CLEANING OF HEADS AND TAPE PATH
Generally, it is sufficient to clean heads after every 10 hours of operation, However, all surfaces over
which tape travels should be cleaned before making high quality recordings.
1. Set the POWER switch to OFF and remove cassette door lid by pushing it up and then taking it out
toward the front side after opening the door.
2. Wipe the heads using a cleaning tip slightly moistened with commercially available head cleaner.
3. Wipe the capstan and pinch roller using another cleaning tip slightly moistened with the commercially
available rubber cleaner.
4. Replace the door lid.
- Do not insert cassette until the cleaner dries out.

DEMAGNETIZING HEADS
Residual magnetism will gradually build up on the heads through continuous use and cause erasure
of high frequencies and hiss. The heads and metallic parts of the tape path should be demagnetized
after 20-30 hours of operation with a commercially available head de magnetizer. Be sure the-
cassette deck is turned off.
CLEANING CABINET
Clean the cabinet, panel and controls with a soft cloth lightly moistened with mild soap solution.
Do not use any type of sourcing powder or solvent such as alcohol or benzine.
