Can not change battery on Polar chest strap

My Polar chest strap provides "easy" access to change the battery.  The problem is the little indention intended for a coin or screw driver is a bit stripped.  I can not get the cover to budge.  Are there any tricks for getting it unscrewed?   Thanks, Gil

Can not change battery on Polar chest strap


Yes, there are a few.1) As you may noticed, coin and even screwdriver blades are never sharp, but mostly blunt. So, sharpen the edge of the coin on a piece of sandpaper. Get hardened steel screwdriver or very sharp, pointed end file and scrape that indention (groove) to make sure the channel have straight sides, forming I_I shaped groove, but not V shaped groove. When done, insert the sharpened coin and unscrew the battery cover using some pressure as well.2) In case if the groove is stripped completely, you will have to drill two small holes into the battery cover. Drill them 1mm from the battery cover's edge on opposite sides. Depth of holes should be 0.5 mm. Do not drill through completely. For drilling use 0.3-0.5 mm diameter drill bit.When finished with both holes, take hardened tweezers, insert each arm into separate hole and unscrew the battery cover.Do not forget to rate, please.

Erratic reading My F11, less than 8 mo old and used no more than 20 times, does not read the HR any more. It either reads "0", or starts with a reasonable resting HR and immediately starts going down, or sometimes during the work out it reads over 200, then drops to 65, all over the place. I thought it might be the battery so I changed the battery on the chest piece, no difference. I always clean the band after a workout, and moist my skin and keep the strap tight during the excercise. I enjoyed the monitor while it worked, and didn't change anything in the way I use it but now it doesn't read anymore. Does it need a technical service? already? is it in warranty? Thanks


It still under the warranty, so, in worst case you can send it back for repair at no cost to you. But first try to use this link:http://www.polar.fi/en/support/downloads?product=&category=User+manualsThis may help to solve the problem yourself.Rate me, please.

My Polar HR monitor ce0537 do not pickup Hart rate


Had the same problem. Just figured it out. The center Polar Logo on the strap needs to touch your chest in a firm way. Bend it back slightly so it fits snug on the middle of your chest.

I have a Polar F11 Heart Rate Monitor. The watch won't pick up the heart rate from the sender (00 is displayed), but my heart rate shows on a Polar enabled Gym machine, e.g. xtrainer. I've changed the battery in the sender.


There is a step by step guide in my tips and tricks of things to try with your strap. If none of these work and you are getting a signal from another source then you need to get either a new strap, a new sender or both. If you send the T-31 wearlink into polar they can run a diagnostic and see which is bad and sell you just the piece you need or a whole new chest piece.

My F11 Polar HR monitor is not working correctly


You should have someone who is use to servicing heart rate monitors take a look at it. There are parts in the monitor that can corrode and would need to be cleaned. Also, look into replacing the battery in both units (Strap and wrist) and make sure the unit is reset properly.
