3.2 Preparation for Installation 
3.2.1 Preparation for Installation Site 
1.  Ensure that the site meets all safety, environmental and power requirements. 
2.  Check that required power sockets are available. 
3.  Check that a network connector is available if the monitor needs to be connected to network. 
 
 
Environmental Requirements 
To avoid explosion hazard, do not use the equipment in the presence of flammable anesthetics, vapors or liquids. The 
environment where the monitor will be used should be reasonably free from vibration, dust and corrosive substances. 
If these conditions are not met, the system may not function normally. 
 
The environmental specification is as follows: 
 
Main Unit (Passport 8/cPM 8) 
Item  Temperature (°C)  Relative humidity (noncondensing)  Altitude (kPa) 
Operating environment  0 to 40  15% to 95%  57.0 to 107.4 
Storage environment  -30 to 70  10% to 95%  16.0 to 107.4 
 
Main Unit (Passport 12/cPM 12) 
Item  Temperature (°C)  Relative humidity (noncondensing)  Altitude (kPa) 
Operating environment  0 to 40  15% to 95%  57.0 to 107.4 
Storage environment  -20 to 60  10% to 95%  16.0 to 107.4 
 
Sidestream CO
2
 module 
Item  Temperature (°C)  Relative humidity (noncondensing)  Altitude (kPa) 
Operating environment  5 to 40  15% to 95%  57.3 to 105.3 
Storage environment  -20 to 60  10% to 95%  57.3 to 105.3 
 
Microstream CO

 module 
Item  Temperature (°C)  Relative humidity (noncondensing)  Altitude (kPa) 
Operating environment  0 to 40  15% to 95%  57.3 to 105.3 
Storage environment  -20 to 60  10% to 95%  57.3 to 105.3 
 
NOTE 
  The environmental specifications of unspecified parameters are the same as those of Passport 12/cPM 12 
main unit.
