You can upgrade parameter modules, functional assemblies and software by connecting the 
patient monitor to a PC running the System Update Tool.   
 
NOTE 
z  If you have to disassemble the patient monitor for software upgrade, be sure to 
eliminate the static charges before disassembling the equipment. When 
disassembling the part labeled with a ESD warning symbol, make sure you are 
wearing electrostatic discharge protection such as antistatic wristband or gloves to 
avoid damaging the equipment.

by force, the equipment may be damaged and the screws or part may fall off 
during use, causing unpredictable equipment damage or human injury.

may be damaged permanently.

any cables or connectors.
