11.2.5 APT Mode
Once the mattress is fully inflated, a confirming signal sounds and the mattress switches into APT Mode (Alternating
Pressure Therapy). APT Mode with pressure level 3 becomes automatically default mode if SCU is turned off for a long
time. APT Mode is intended to be used as an aid to patient care in prevention and treatment of skin breakdown related to
pressure damage.
To select APT mode:
Press button
13
once or repeatedly until indicator
4
comes on.
When APT mode is switched on:
3-cell mattress units will inflate and deflate in cycles of 7.5 minutes.
Indicator

lights white.
Pressure indicator
3
flashes.
Once the pre-set pressure is reached, indicator
3
will remain solid on.
NOTE After 3 cycles of APT Mode with deflated individual cell an alert indicating fail to inflate is triggered.
11.2.6
Max Mode
Max Mode (maximum inflation mode) provides a solid and stable surface for patient care.
Max Mode will run for 30 min at most. If no other mode is selected within last 5 minutes, a confirmation signal will sound,
and the mattress replacement system will switch back to APT or CLP mode automatically. Selected Max Mode interrupts
the return to the previous mode.

flashes white until preset pressure is reached.
Once the set pressure is reached, indicator
5
will remain solid on.
During the last 5 min, an alert signal will sound every minute.
When Max Mode is selected for the second time:
During the last 5 min, an audible reminder will sound every minute to remind the personnel that Max Mode

11.2.7
CLP Mode (Constant Low Pressure Mode)
CLP Mode (constant low pressure mode) keeps the mattress pressure at the selected level. The pressure is checked
every 30 seconds, and adjusted if necessary. CLP Mode is intended to be used as an aid to patient care in prevention of
skin breakdown related to pressure damage.
To select CLP Mode:
Press button
13
once or repeatedly until indicator
14
flashes white.
When CLP Mode is switched on:
CLP indicator
