3-4-2 Notes on Handling

Handling
The Professional Disc is housed in a
cartridge, and is designed to allow handling
free of risk from dust or fingerprints.
However, if the cartridge is subjected to a
severe shock, for example by dropping it,
this can result in damage or scratching of
the disc. If the disc is scratched, it may be
impossible to record video/audio, or to play
back the content recorded on the disc. The
discs should be handled and stored
carefully.
• Do not touch the surface of the disc itself
within the cartridge.
• Deliberately opening the shutter may
cause damage.
• Do not disassemble the cartridge.
• The supplied adhesive labels are
recommended for indexing discs. Apply
the label in the correct position.
Storage
• Do not store discs where they may be
subjected to direct sunlight, or in other
places where the temperature or humidity
is high.
• Do not leave cartridges where dust may
be able to gain ingress.
• Store cartridges in their cases.
Care of the discs
• Remove dust and dirt on the outside of a
cartridge using a soft dry cloth.
• If condensation forms, allow ample time
to dry before use.
