4-8 General Maintenance for the Standard Display
• Installation, use, maintenance and de-mounting of this equipment must
be carried out by authorised technicians only.
• Take good notice of the “Safety rules and precautionary measures” in the
front of this manual.
The Standard Display does not require special maintenance unless it is
used in low-temperature applications and/or surroundings with high
humidity (above 90% annual mean). It is the customers responsibility to
take all precautions to
dehumidify the internal atmosphere of the Standard Display in such a way
that no condensation will take place, for example by placing dry silica-gel in
the casing. Furthermore, it is required to replace or dry the silica gel time to
time as advised by the silica gel supplier.
Battery life-time:
Is influenced by several issues:
- Display update: see setup 41.
- low temperatures; the available power will be less due to battery chemistry.
