PR SystemOne LCD Screen Question

[Slinky]

I was going thru the various information and settings on the PR SystemOne. According to the manual I should be able to turn the LCD screen backlight On - but the only backlight I was able to turn on was for the Humidifier icon. It is very difficult to read the screen w/o a backlight on. So far I've used a flashlight to shine on the screen as I scroll thru. That is very inconvenient. Any suggestions?

Also, does anyone have the definition for "periodic breathing" or "period breathing"?? Supposedly I am encountering that 4% of the time I'm using my PR S1. My AHI has been 7.6. Why in the devil don't they give us the AI on the screen too??? Grrrrr.

Yep, one of my biggest complaints about the PR1 - the LCD screen without a back light is very difficult to read.
I too had to use a flashlight to read the screen. I used a small but bright LED flashlight.
This is a problem I have with the manufacturers of user end medical devices.
I am a diabetic and I could never understand by glucose meters and insulin pumps have the smallest, cheapest, junky and hardest to read LCD screens.
Considering that a lot of diabetics have vision problems you would thing they would put in a nice back lighted easy to read display.
By the way I now have a Resmed S9, what a gorgeous, bright, easy to use, color display it has which goes off after use in a couple of seconds so no complaints from the light haters - way better display than any x-pap on the market today.
