Mother Board Removal 

 

Remove the cables connected to the 
mother board (as shown). 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

Remove the UTK 
(Item 35) prior to PCBA 
removal to avoid 
damaging the connector. 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Refer to the Item Identification Table for the correct item, as there are two versions of WAM/UTK pairs 
that must match (v1 to v1 or v2 to v2) for the wireless interface to operate properly. Units utilizing the 
v2 UTK will have a round “2” label (item #65) near the ECG input connector on the housing.
