Hi Alan , Our MRx's only have NIBP and yes they do come up with a reminder - however the cal is at 0 and 250 mmHg - very quick and simple .
There is no requirement to check charge time to 200J on both battery and AC on the MRx - unlike the HearStart XL - the local Philips guys tell me the charge time on battery is a battery test rather than a chatge time test - on battery the spec is 0 to 200J in 3 secs and AC 0 to 200J in 15secs - and as a result we are going to change all the battries - they vary between 2 and 4 years old
I would have thourght the MRx would have had the same test - however not
Cheers George
