4.1.7 CO above 15ppm (Failsafe) Protection Beep
The 717R will not allow the user to either Turn the instrument OFF or to move to
another Function whilst the CO level is above 15ppm. A short beep will be heard
should the user attempt either of the above with the CO above 15ppm.
This is a Failsafe Feature of the 717R to protect the instrument from giving false
readings when next turned on. The 717R should be run in a clean air environment
with just the In-Line Pump Protection Filter attached until the CO level drops
below 15ppm. The 717R will then be able to be moved to a different function
screen or be turned OFF.
