6 Hardware Upgrade 
 
 
6.1 Adding the SpO
2
 Function 
The TM80 is equipped with the SpO
2
 interface and the SpO
2
 function can be added 
through upgrade during later use. The SpO
2
module is on the SpO
2
extension cable.   
 
Required materials 
If you need to add the SpO
2
 function, you need to purchase the dedicated SpO
2 
extension cable andSpO

 module and then connect the 
SpO
2
module to SpO
2
 connector in the TM80. 
 
Verification method 
Apply the SpO
2
 sensor to appropriate site of a patient. SpO
2
 waveforms and values 
are displayed on the screen. For a health adult, the SpO
2
 value should be above 90% 
and SpO
2
 waveforms are rhythmic. On the CMS, corresponding waveforms and 
values can be seen. 
 
 
6.2 Adding the NIBP Module (BP10) 
The TM80 is connected to the BP10 module over MPAN and the NIBP function can 
be added through upgrade during later use. The BP10 module is an independent 
module. It completes NIBP measurement independently and sends data to the 
TM80 over MPAN.
