Leak in cuff
or hose
The unit has detected a
large leak in a cuff
defined as the cuff
failing to reach the
pressure set point in a
reasonable time, or the
pump running
excessively while
regulating in ‘Inflating’
or ‘Regulating’ mode
and the pressure set
point is not being
adjusted.

Reduce pressure set point until
unit can maintain pressure
OR
Press and hold ‘DEFLATE’ for 2
seconds to deflate the cuff.
Calibration

The unit has detected
that the calibration in
the pressure transducer
is invalid. The unit has
shut down in a safe
state*.

When cuff deflation is required,
disconnect hose to cuff.
* In the ‘safe state’ mode, the current pressure in the cuff is held (in the absence of leaks). The ‘safe state’ mode helps prevent unexpected
loss of occlusion during a procedure if a sudden failure occurs. See Section 2.8.2 for more detail.
