[Resolved] Changing the Pressure on Model 11 Unit

I was told by a person at my vendor (Apria) that once the pressure has been set at the factory on a ResMed 11 CPAP standard machine and is delivered to the user, neither the factory nor anyone else can change it. Is that true and if so, what happens if the machine arrives with the pressure set too high or too low?

It's a bold face lie....pure and simple....The pressure is easily changed if you know how to get to the clinical set up menu and that's easy.
