Shortcut battery with AC contact. AC can be found on the sides of watch movement(very tiny). You have to use pointed tweezers: one end on battery+, another on AC contact for three secs..

I had the same problem. So I will try to guide you by button push method (because I didn't understand anything in Dutch that said on the panel). If you look at the polar main wrist watch (easy to say) you will see 5 button. 2 of left and 3 on right. 2 left are top -backlight (21) bottom - back or exit from menu (22). The 3 right buttons are top - scroll up (31), middle - menu (32) and bottom -scroll down (33). Now we know the button number here we go.

Hold 22 for 3 sec. You will see current time showing up. Press 33 once -- Setting ---> press 32 once ---> watch time and date ---> press 33 three time ----> general setting shows up ----> press 32 once ----> button sound shows up ---> press 33 twice ---> language shows up --->press 32 once ----> language blinks ----> press 33 or 31 till you see english or your language of choice ---->press 32 once ----> language is set ---->press 22 for 3 sec and you are back to the watch menu. Hope that helps. This will guide you even if you don't understand anything from the language.

Someone posted a link on how to change the batter on an F11. If it's not longer under warranty or you just don't want to bother with sending it back and the extra costs, you could follow this: http://timlaqua.com/2008/09/how-to-replace-the-battery-in-a-polar-f11-heart-rate-monitor-hrm/

Press and hold the LIGHT button (top left button) to manually unlock. It's on page 23 of the manual. (Assuming you're talking about keylock.)

unknowingly you know the exact problem.change the battery if does not work .take it to the repair center.thanks.

try a new battery

no it shouldnt be cause the heart rate would be based off your pulse

im not a heart specialist but ive had my share of heart polups and a faulty valve in my heart
i was told by my doctor that the heart rate is monitored by bloodpreasure threw the veins pulse so i dont think that the size of the watch would make a difference this is in my opinion based off my own docs words hes the doc what can i say

but recommend that you speak with your doctor about heart monitor watches they know more indepth about these devices or your local pharmacy

i hope this helped you out

Hello,

The reset will always solve the issue. It may have been due to Electromagnetic Interference or Static Electricity.

You can press and hold ALL buttons at the same time for 10-15 seconds. After that, simply reset the time/date. All saved information will be stored.

If you are still having a problem feel free to contact Polar Customer Support @ www.polarusa.com.

Hope this helps.
