Question about Polar F11 Heart Rate Monitor

3 Answers

Polar F11 blank display

In the battery change I put it in the wrong polarity.
My F11 is now in blank display.
It likes to run, make bips, but can't light up running.

The most intersting yet, it looks good when I reset it (3 buttons for 3 seconds)!!! It keeps very good characters until I press ok.
Then, go blank again.

What can I do (by myself) to fix it???
Thanks a lot.

Probably too late for you but could be you need to reassemble. If any portion of the watch doesn't seat right then the display may not work properly.

Sounds to me as the integrated circuit has been damaged.
In this case you will not be able to repair it yourself as watchmakers skills needed.

Instructions to reset a nordictrack cardio track watch

You may have started wearing a Polar F11 Fitness heart rate monitor to help you keep track of your pulse during cardiovascular exercise. The monitor consists of a strap with electrodes that you attach to your chest, which transmit heart rate data to a receiver worn on your wrist like a watch. The wrist unit stores data and settings that you can customize, such as your weight, height and target heart rates. However, you may wish to reset the unit and start over with new settings. You can reset your Polar F11 by following a few easy steps.

    • Press any button to activate the Polar F11 Fitness heart monitor unit.
    • 2 Press all buttons on the Polar F11 Fitness heart monitor simultaneously, except the "Light" button. There are five buttons and the "Light" button is at the top left side of the unit. Continue to hold the buttons until the display fills with digits.
    • 3 Press the "OK" button, which is located on the right side of the unit in the middle of the up and down buttons. The Polar F11 Fitness heart monitor will reset.

    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...

    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.

    Try resetting. From the manual, "if there are no reactions to any buttons, reset the wrist unit by pressing all the buttons simultaneously for two seconds. All other settings but time and date are saved."

    Is it possible the watch block is not in correctly and the display is getting squished?

    Polar F11 ''Scrambled/Smudged'' Display

    You have to replace the battery with the new one. In most cases underpowered battery causes faded or even disappearing digits on LCD unless your watch has been damaged by water. Find your nearest watch repair shop or do it yourself. Do not forget to rate, please.
