Static/Alternating Pressure Button
1. Press the Alternating Pressure button (
 The alternating pressure times indicate the frequency of deflation or inflation of half of the air cushions (even or odd numbered). For
example, 10 minutes is selected. In this example, the even numbered air cushions in the mattress will deflate, while the odd numbered
cushions remain at constant pressure. When 10 minutes has elapsed, the even numbered air cushions will inflate while the odd numbered
cushions remain at constant pressure. When 10 minutes has elapsed again, the odd numbered air cushions deflate while the even
numbered cushions remain at constant pressure. The air cushions continue to inflate or deflate like this as long as an alternating pressure
time has been selected. At all times, half of the air cushions remain at a constant pressure when an alternating pressure time has been
selected.
In Static Mode, all air cushions in the overlay are maintained at constant pressure. The Static LED is illuminated Green.
Adjusting the Minimum Pressure Setting (A/P Low)
The minimum pressure setting during Alternating Pressure is set to 0 (2 mmHg) at the factory. This means that the overlay will deflate as much as
possible during the deflation time when using 10, 15 or 20 minute Alternating Pressure times. The setting can be changed so the overlay will only
deflate to 25%, 50%, or 75% of the selected pressure setting.
1. Ensure the Standby LED is lit.
2. Press and hold the Max Inflate and Fowler buttons.
3. Read the LCD Display. The LCD Display will flash:
• 0 if the current setting is 0 (2 mmHg).
• 2 if the current setting is 25% of the selected pressure.
• 5 if the current setting is 50% of the selected pressure.
• 7 if the current setting is 75% of the selected pressure.
