1. Turn the power switch
to the ON position.
2. Adjust the pressure
adjust knob to the maxi-
mum position.
Note: Set the pressure adjust knob to the maximum position
for the quickest inflation at set-up; the mattress can then be
adjusted to the desired pressure.
3. The pump will begin
delivering air into the
mattress. While the mat-
tress is filling, the low
pressure indicator (yellow LED) will illuminate.
4. When the selected pres-

the low pressure indica-
tor will de-illuminate,
and the normal pressure indicator (green LED) will
automatically illuminate.
5. Replace all sheets, blankets, and pillows on the bed.

Generally, a lighter patient will need a lower (softer) set-

setting, but pressure adjustment must ultimately be based
on the patient's
weight distribution
. A short, stocky person
may be the same weight as a tall, thin person, but their
settings will not be the same. The mattress should be firm
enough to support the patient, yet soft enough so the
patient will sink down to eliminate pressure points.Test the
pressure by placing four fingers below the mattress under
