securely plugged in. 

Unit does not turn on 
(with AC power 
connected). 

Internal hardware 
failure.  Defective AC 
adapter/cord assembly. 

Contact Delfi.

blocked. 

 

Internal hardware 
failure 

Press and hold the ‘DEFLATE’ button for at least 
2 seconds. 

Unkink hose or disconnect cuff from hose.  
Ensure complete cuff deflation to clear “CUFF 
NOT DEFLATED” alarms. 

Contact Delfi. 

Green AC indicator light 
does not illuminate when 
unit is plugged in to AC 
power. 

AC power supply 
assembly not plugged 
in to suitable wall 
outlet. 

AC power supply 
assembly not plugged 
in to P.T.S. unit.
