CD Handling
• Always hold the disc by the edges, so as not to make fingerprints
on the disc or scratch the printing.
• Never touch the recorded side of the disc. Do not place the disc
directly on anything hard.
• Do not wet the disc with volatile alcohol or water, as there is a
possibility of the label printing disappearing.
• To write on the disc label surface, use a spirit-based felt pen. Do
not use a ball-point pen or hard-tipped pen, because there is a
danger of scratching the surface and corrupting the data. Do not
use adhesive labels.
• Do not expose the disc directly to the sun's rays, or keep it in
conditions of high temperature or humidity, as there is a danger
of warping, with consequent loss of data.
• To remove dirt, dust, or fingerprints from the disc, wipe with a dry
cloth, or use a CD cleaner. Always wipe from the inside to the
outside, and do no wipe with circular movements. Never use
abrasives or solvent cleaners.
• Hioki shall not be held liable for any problems with a computer
system that arises from the use of this CD, or for any problem
related to the purchase of a Hioki product.
