REMstar Plus C-Flex ?

G'Day Users,
I recently purchased this used machine on CraigsList, the "User Manual" is labeled REMstar Plus C-Flex. but it doesn't show up on the LCD Display Home Screen.
I searched the internet and found what I think is the Clinical Menu but can't find anything about C-Flex when I enter it, I read on this forum that every plus series has C-Flex ?
As for the numbers on the bottom of the unit, I have REF150P. Is there something I'm missing ?
Thanks.

No, not missing anything. CFlex exhale relief is only available on the 250/260 and 450/460 models.
The 150 is the most basic of models and it doesn't have CFlex.
Some how or other it got the 250 manual..maybe there wasn't one.

The 150 is simply the PR System One Plus CPAP
The 250 is the PR System One Plus CPAP with CFlex.

Not all PR System One machines offer exhale relief (that's what CFlex does). If you read that all "Plus" machines have CFlex.. that statement was an error but whomever said it may not have known about the basic 150 model.

Thanks Mate.
I guess the guy I bought it off didn't even know that, (15hrs on the blower) just went by the Manual that came with it.
Thanks again.
