Polar Chest Strap

I've had my Polat FT4 for about a year now and have loved it. Recently I have been having issues with the chest strap not transmitting very well. It'll show 00 on the watch. I've tightened the strap and wetted it as much as I could. Has anyone else had this issue? If so what did you do to fix it?

  • Yes, with the brand new I bought. It didn't even work out of the box and did the same thing you described. I returned it to Amazon and bought another one. Works fine. I know that isn't much help, have you contacted Polar?

    Have you washed it? Sweat build up can cause it to have difficulty reading. I rinse my FT7 strap after every workout (and rub the sensors) and wash it in the washer with a load of towels every 5-6 uses (per Polar's instructions)

    Sounds like the battery to me. I had this problem, but it was the battery in the receiver causing it in my case.

    I have the FT7 & had the same issue.... If it isnt the transmitter battery then the transmitter is faulty. I would try to replace the battery 1st. If that doesnt work, contact Polar customer support

    Have you washed it in the washing machine? And have you changed the batteries

    I have a polar chest strap and watch. The watch battery went well before the strap battery. I would suggest trying out the band with a treadmill or cardio machine that links to the band and see if it's still not working correctly.

    You need a new battery. That is probably all.

    I also have a Polar HRM, but never had any problems with it yet; so I'm just guessing now but I think there is a high possibility that it might be a dead battery issue in that transmitter device which goes on the chest strap, especially considering you used it for a year.

    Polar sucks. No, seriously. Go buy a Garmin device. It makes Polar look like the toy that it is.

    I haven't changed the battery yet. Haven't really washed the strap except for rinsing it in water when I'm done. I'll throw it in the wash and see if that helps! As well as changing the battery!

    The battery in the transmitter is probably dead. The same thing happened with mine recently! The only thing that I could do was replace the transmitter because I couldn't get the backing off.

    if you have had it for a year, get a new battery for the transmitter, Mine went just over a year, they are pretty cheap as it is just a flat watch style battery

    I'm having a similar problem with the FT60. The first few times I used it, it would stop working within 10 minutes. Thought my sports bra was rubbing against it and moving it. New sports bra, tried it again, and it wouldn't transmit anything. Since it was still under warranty, I sent it off to the company for service last week.

    Time to change the battery. I just replaced the battery in my watch and the strap. It's easy to do and fixed that problem.

    If you change the battery, dont you need the seal as well?

    I use an electrode gel to help with the transmission. I apply the gel to the strap and then wet the skin. No more problems.

    This is what I use: Parker Spectra 360 Electrode Gel. The tube sells for less than $6 on Amazon and goes a long way.

    I had this thought too, but I wasn't sure if most people have access to that. My elliptical came with a polar chest strap, and reads my FT4 if I don't use the machine's strap. My receiver showed 00, but the machine read my hr just fine. This showed me the transmitter wasn't the problem, which makes sense anyway since the watch doesn't turn off. Changing that battery fixed my issue.

    that's your problem, right there. The instructions state that it needs to be properly washed, on a frequent basis.

    I put mine in a lingerie net bag, and toss it in the washer with my workout clothes once a week. If i ever have trouble with the strap, it's because I've forgotten to toss it in the washer that week.

    (don't put it in the dryer, though)

    Have you washed it? Sweat build up can cause it to have difficulty reading. I rinse my FT7 strap after every workout (and rub the sensors) and wash it in the washer with a load of towels every 5-6 uses (per Polar's instructions)

    I thought I read in the instructions that you should hand wash it every 5-6 uses with soap and warm water? I have the FT4 though, so I don't know if the instructions are different.

    Yes, they say to only hand wash them. I let mine soak in the sink for awhile in warm water and a little soap and then hang to dry.

    If a battery change doesn't help try off-setting it slightly to the left.

    I find if it's exactly central over my sternum I can get a poor signal as it's not in very positive contact with my skin. Slide it over slightly and see if that improves it.

    I have an FT4 & FT60 and both have this problem. Batteries are new, chest strap washed right after a workout (placed in washing machine 2 times a week) and it still does it sometimes. It's all about placement. Plus other things can interfere with the signal I've found.

    I just had the same issue. Changed the battery on the transmitter and it still read 00. Washed the strap and then it worked just fine.
