Help on Setting My GoodKnight 420E!

[DCTom]

Somehow my Puritan Bennet Goodknight 420E won't set on even numbers for my pressure settings. It goes like 8.3, 8.5, 8.7, etc. And also, next to the pressure setting numbers on my screen it shows hPA instead of cmH20. Does anyone know what I should or can do? Thanks!!

Just a guess but it sounds like it is displaying in hectopacals instead of CM H20. Have looked through the book I have but there is no reference to how this setting is changed. A quick google of " 420e hPA" shows the 420e is capable of from 400 to 1060 hPA. Me thinks you need to phone PB for some help.

I don't have a clinician's manual, so I can't help you, but I remembered this post - added my emphsis to the quote.

zeee French 420E and the DME by Snork1

Maybe its just me, but I found this hysterically funny.....

After all the usual problems of being jerked around by my DME, I finally get an appointment to pick up my 420E machine. They come out to the lobby and tell me they'll be right back, but they just have to "grab my machine".

Almost an hour later.......

They (a trained professional RT and seasoned customer service person) come out and apologise for it taking so long, but they were apparently given a FRENCH machine and it has taken the two of them together that long to get it into english and change ONLY the pressure settings (wrong settings, but that a digression.)

So I toddle off, having begged a clinicians manual from them and thinking it would indeed be hard to figure things out, if all these commands are staring at you in French.

It takes me two days to finally realize.....there are NO WORDS on the settings on the machine, only symbols and numbers?
WTF is FRENCH????!!! ...pardon the french....

I finally figured it out. The machine had the pressure in metric/si units (hPa) instead of "english" (cm, H2O....which is still technically "french").
Which also takes about 5 minutes, if you are very unlucky and miss it at first, to find in the manual, and how hard is it to hold down the hidden button while plugging in the machine to toggle this, as clearly stated in the manual? I would say that adds at least another 10 seconds.

"French" settings......

Yep you are right! If you hold down on the 2 buttons while plugging it in, then it swtiches back to American and not French.

A disadvantage of the "French" mode is the garlic smell of the air pumped through your hose, of course.
