my polar hrm not working :(

Make sure the strap is tight enough. Maybe rinse the electrodes on the strap with distilled water.

I have a FT7 & it does that if the transmitter isn't flat against my chest or if the strap isn't wet enough. Good luck.

I've had a couple of different Polar HRM's and usually if it wasn't working, it was either the strap battery or the watch/computer battery. I haven't had your exact model, though.

Six months sounds short for battery life to me. The computer battery on my bike computer usually lasted a year (or even two); seems like the strap batteries didn't last as long - and that was using it two to three times a week at most. More frequent use will, of course, reduce battery life.

I'd try replacing the strap battery if you haven't already. If your strap is the kind with the transmitter module that snaps and unsnaps, make sure it's oriented correctly on the chest strap (mine only goes one way, though I think if one were to try hard enough, it could be forced the wrong way).

That happened to my FT7. Tried everything, couldn't fix it. I've given up on using a heart rate monitor, which hasn't made a difference in my results since I used it long enough to get a good idea of what I burn.

I've had an FT4 for over a year and it's recently been doing that to me too. I usually just adjust the strap because it isn't lying flat on my skin and it's fine.

Sometimes my HRM registers my pulse intermittently, I discovered that making the contacts damp gives it better connection with the skin.

When you store your strap away you are supposed to unsnap the controlller bit and store that and the strap separate. Otherwise the batter y drains quicker. Thats what happened to mine anyway (didn't read the instructions doh!)

I've had this a couple of times. Clean the electrodes and strap. Separate and clean the transmitter and strap when not in use as it drains the battery. Wet the strap and electrodes before use. Make sure it is snug but not too tight and flat against your chest and not moved around by your sports bra. If it is still playing up, change the battery in the transmitter; it might seem like it has a short life, but if you are using it a lot, it will discharge!

Yep, mine was the same after about 8 months, sent it back to Polar, who 'fixed it'....it worked for a week then did the same thing again. I sent it back to Polar who 'fixed it' again and sent me a new strap, it doesn't work. I've also seen other friends have the same experience so Polar isn't all that it's hyped up to be. I'm very disappointed and now back to guesstimating calories burnt via mfp.

I have ft4. You need to rinse the electrodes well in plain water after every use and hang to dry. No soap or fabric conditioner. Also, my old strap only lasted two years. It was one where the electrodes are fabric and you had to dampen them before use. They eventually began to fray and stopped working. Bought new strap not transmitter, this one has rubbery electrodes not fabric and a fabric strap. You don't have to wet it before use. Works a treat. My batteries lasted over a year in both watch and transmitter.
I think sweat build up can affect the connection, all that salt, so do rinse it well.

Me too.:laugh: I just unplug one side and spin it around. I don't have to look for it in my gym bag that way. (Lazy mode) I also bought the new Soft strap, way better than the original, I don't have to wet it to get it to work.

I've been having the same problem with my FT-4 lately. It's a real PITA when you're in the middle of a workout, and then that dreaded message pops up. :grumble:
