Have older machine from 2001, REMSTAR Plus LX and I need help finding the pressure adjustment settings. Help?

A member PM'd me and said the above instructions may not work for the LX but these are from the LX manual.
Chapter 4: System Setup Procedures
4.1 Overview
This section provides an overview of the system setup including detailed
required, alternate, and optional circuit accessories. See Chapter 5 –
Routine Maintenance, for filter and filter cap installation instructions

CAUTION: If the REMstar LX and REMstar Plus LX CPAP
Systems (REMstar LX and REMstar Plus LX) have
been exposed to either very hot or very cold temperatures,
allow them to adjust to room temperature (approximately
two hours) before beginning setup.

4.2 System Setup (Dealer Mode)
Step 1 If installed, remove the protective cap from the air outlet.
Install the test orifice (RI P/N 622032) onto the unit outlet.
Step 2 Plug the male end of the AC power cord into an electrical
outlet.
Step 3 Simultaneously, press the two User buttons and plug the
female end of the AC power cord into the AC inlet on the
back of the unit. Hold the two User buttons down to enter
dealer mode.

4.2.1 Self-Diagnostic Test
After the unit is plugged into an electrical outlet, it will perform a Self-
Diagnostic Test.
The blower will turn on and the 2- digit LED display will indicate the
altitude setting.

4.2.2 Setting the Altitude
The altitude may be set in the either Dealer mode or User mode. While
holding down the two User buttons or the key pad, plug the AC power
cord into the unit. The altitude setting will be displayed on the 2-digit
LED. To ensure proper therapy, this setting needs to be accurate for the
patient’s current location. The altitude displays are:
LOW 0 – 2,500 ft. (0 – 762 m)
MID 2,501 – 5,000 ft. (763 – 1,524 m)
HIGH greater than 5,000 ft.

If the correct setting is displayed, press the left User button. To change
the altitude setting, press the right User button until the correct setting is
displayed.

4.2.3 Setting the Ramp Time
The minimum ramp pressure is factory set at 4 cm H2O and cannot be
changed. The ramp time can be set from 0 to 45 minutes (5 minute
increments). The first time the ramp button is pressed, the pressure will
reduce to 4 cm H2O and then increase in a linear fashion over the set time
period until the pressure setting is reached. After the first activation, each
subsequent ramp will be for one-half of the set ramp time. The blower
must be turned off with the Pressure On/Off button and then back again to
reset the ramp to the full time.
a. To view the ramp time setting, enter the system set-up by
simultaneously holding the ramp and pressure on/off buttons down
while plugging the power cord into an electrical outlet. Release the
button when the unit turns on.
b. The airflow will automaticaly turn on and the display screen will
show the current elevation setting.
c. Press and release the on/off button to view the ramp setting.
d. To change the ramp time setting, press and release the ramp button
until the correct setting is displayed.

4.2.4 Setting the Pressure
The pressure may set without the use of a manometer. The
manometer is only needed if pressure accuracy is suspect. If
pressure accuracy needs checked follow steps a - g.
a. Connect the following:

• 6 ft. Smooth-Bor tubing to the outlet port on the unit.
• Whisper Swivel II to the 6 ft. Smooth-Bor tubing.
• Test orifice 60 lpm @ 14.4 cm (RI P / N 622032) to the
Whisper Swivel II.
• Manometer and pressure tubing to test orifice.
• Occlude test orifice.
b. Ensure the blower is off. Unplug the AC power cord from the
unit. The green LED will go out.
c. While holding down the two User buttons on the
key pad, plug the AC power cord into the unit. The
same displays used for the Minimum Pressure Test
(see Section 8.2) should be visible.
d. Verify the following:
• the blower is running in the unit; and the proper altitude
setting is indicated on the display.
e. Press the left User button twice until the Pressure display
appears.
f. Press the right User button until “20” appears. Each press of
the right User button increments the pressure by 0.5 cm.
g. Press the Blower On / Off button and verify the pressure on
the manometer is 20.0 cm H2O (±2.25 cm H2O).
