Maintenance Task and Test Schedule
The following tasks are for Philips-qualified service professionals. All maintenance tasks and
performance tests are documented in detail in the service documentation supplied on the monitor's
documentation DVD.
Ensure that these tasks are carried out as indicated by the monitor's maintenance schedule, or as
specified by local laws, whichever comes sooner. Contact a Philips-qualified service provider if your
monitor needs a safety or performance test. Clean and disinfect equipment to decontaminate it before
testing or maintaining it.
Storing Recorder Paper
Recorder paper is not intended for long-term archival storage. Another medium should be considered
if this is required.
Dyes contained in thermal papers tend to react with solvents and other chemical compounds that are
being used in adhesives. If these compounds come into contact with the thermal print, the print may
be destroyed over time. You can take the following precautionary measures to help avoid this effect.
• Store the paper in a cool, dry and dark place.
• Do not store the paper at temperatures over 40°C (104°F).
• Do not store the paper where the relative humidity exceeds 60%.
• Avoid intensive light (UV light), as this may cause the paper to turn gray or the thermal print to
fade.
• Avoid storing the thermal paper in combination with the following conditions:
– Papers that contain organic solvents. This includes papers with tributyl and/or dibutyl
phosphates, for example recycled paper.
– Carbon paper and carbonless copy paper.
– Products containing polyvinyl chlorides or other vinyl chlorides for example (but not
exclusively) document holders, envelopes, letter files, divider sheets.
– Detergents and solvents, such as alcohol, ketone, ester and others, including cleaning and
disinfecting agents.
