Polar HRM alarm question(4 posts)

Polar HRM alarm questionlaffeaux

I've just started riding with a Polar heart rate monitor - s720i model (basically an updated s710), and I'm having trouble with the alarms. Any help would be appreciated.

The problem: I set two limits, Limit 1 at 117-130 and Limit 2 at 131-145, and turned the alarm on. I thought that doing this would cause the alarm to sound when I was either below 117 or above 145 (since the two limits start and end 1 BPM apart). However on my ride today, the alarm would sound when I exceeded 130. It seems like Limit 1 was controlling the alarm. When I checked the stats after the ride, it showed me my time within my Limit 2, so it was set correctly.

How do I get it to not beep until I've surpassed in either direction the combination of Limit 1 and 2? All I can figure is to set Limit 1 to the full range, and Limits 2 and 3 to the sub ranges that I'm interested in. I'd prefer not to do this as I'd also like to try using 3 distinct limits on other rides.

You have to hold down the top right hand button until the HRM switches zones. It doesn't do this automatically.
Feb 12, 2003 4:45 AM can create up to 5 sets of three limits...if it's more convenient you can combine the values of Limit 1&2 and stick them into Limit 1. Then on other types of rides you just call up a different exercise set to suit your needs.
thanks for the infolaffeaux

I was hoping it would be easier to flow from one zone ot the next. For example, I'd like to be able to set it to warn me when I was riding in the 80%-85% range, but not do anything if I was above or below that. For road rides, it's easy enough to try and stay in a designated zone, but for off-road use it's harder to stick to a zone.

Optimally I'd be riding below 80%, and when I hit harder sections, I'd like to be sure to exceed 85%. However if I have to hit a button in the middle of a steep climb, this is not going to happen. Bummer.
