CUFF LEAK
The unit has detected a large
leak in the cuff, hose or
connectors which is defined as
the cuff failing to reach the
pressure set point in a
reasonable time, or the pump
running excessively while
regulating the pressure and the
pressure set point is not being
adjusted.
CUFF PRESURIZED DURING
POWER UP
The unit has detected an
approximate pressure of
50mmHg or more in the cuff
when the unit was powered up.
The unit assumes a procedure is
in progress, changes the
pressure set point to the
detected pressure, immediately
regulates the cuff to this
pressure, and activates alarm to
alert the user of the condition.

The unit's elapsed timer, which
advances when the cuff is
inflated, has reached the time
limit set point and caused the
time alarm to activate.
