Polar FT7 HRM

I've only had mine for a few weeks and I love it. Could it be a battery issue? I know they are supposed to last a lot longer than that, but that's the only thing I can think of. Do you disconnect the transmitter from the chest strap after every use?

No I just rinse it after every use....no soap. And then hang it to dry. Not sure what else it might be. Maybe yours is just defective?? I have not heard any other issues here on the forum. Maybe someone else here can offer some advice. Have you tried contacting Polar for troubleshooting? Wish I could be more help.

Try putting the strap in the washing machine. Hang to dry, don't put it in the dryer. I usually do that to mine every 1-2 weeks to keep the sensor free of oils from your skin.

I wash mine in the washing machine (with all my other clothes but in a lingerie bag) and then hang dry at least once every couple of weeks (since I use it every day).

Try first changing the batteries as well and know you can't get those sensors wet enough.

If these tips don't help, contact Polar about exchanging it.

mine would work fine till i started exercising and then would read 00 or heart rate not found. I finally figured out that it was because i needed to tighten the chest strap. give it a try maybe it will work for you.

Please HELP! I bought my Polar FT7 HRM in August 2011. The last couple weeks when wearing using it my heart rate jumps from about 150 to 220 in seconds and stays in the 200's. It has always worked great but recently has went to crap. I run water over the chest strap after every use like the directions say to do. Is anyone else having any problems with their HRM?

I have the Polar FT4, I gather care of the chest-strap will be similar.

Ensure you rinse it well after every use. After every 5 or 6 training session, stick it in the washing machine, this ensures all sweat and salt is completely washed off.

Don'[t worry, it is safe to do that, it says to do so in the manual. Just don't forget to take the wearlink off of it though, not sure the wearlink would appreciate being spun around in the machine lol.

One other thought regarding your heartrate, forgive me for asking, but you aren't taking any slimming pills are you? The reason I ask is because many years ago I was taking slimming pills that I had bought over the counter in the Pharmacy, they sent my heartrate through the roof to 225 during an aerobics session once. The heartbeat was genuine and I immediately ceased taking them.

well, according to instructions, you should rinse the strap BEFORE, not after using, and wash the strap every other 5 uses.
