A.3 Environmental Specifications
• The monitor may not meet the performance specifications if stored or used outside the specified 
temperature and humidity ranges. If the performance of the equipment is degraded due to aging or 
environmental conditions, contact your service personnel.
• When the monitor and related products have differing environmental specifications, the effective 
range for the combined products is that range which is common to the specifications for all 
products.
• The environmental specification of unspecified parameter modules are the same as those of the 
main unit.
