Polar AXN300 Heart Rate Monitor Watch HRM AXN300 is not showing pulse

I replaced the battery in my chest strap, but the watch is not showing my pulse (it is in the correct mode) The HRM unit on my stepper is monitoring my pulse correctly. I have tried the unit away from the steeper without any improvement. The low battery indicator on the watch is not showing.

I would think it is the sensor circuit in the watch. When you replaced the battery did you activate the processor all reset for the watch? I do not know on your model where or how this would be activated.

Electronic watches normally have a reset procedure for when the battery is changed. Very important the watch's processor reset is performed after changing the battery. This is not any of the user readings reset. This is a reset for the watch's processor and system. It is sometimes a contact that has to be shorted out with the jeweler's screwdriver, or it is a contact that has to be shunted, or etc., depending on the model. Maybe if you call the support for the watch they will tell you this. Normally they do not like the user opening the watch.

I' advise to start with battery check. If the battery is ok, then you will need a professional to find the cause of malfunction.

You certainly have had good service out of the battery. It is best left to a watch repairer to replace the battery.

My watch does not show heart rate


I have a problem solving checklist about getting Heart rate readings in my tips and tricks page that may be helpful.

#1) you have to make sure the strap is across your chest and contacting the skin directly
#2) you have to push the button on the front of your watch to turn it on.

After that it should read automatically, there is no trick to your watch.

Changed the battery and now it won't pick up the heart rate monitor. I know the monitor works because it is picked up by all the equipment in the gym.


If Heart Rate is being displayed on the equipment in the gym, but not your watch, then your chest strap is transmitting fine, but the watch is not recieving the signal.

It is not uncommon that when a battery is changed outside of a polar authorized service center that something can happen to the internal electronics. I would suggest you send the watch into Polar and have them take a look. if you have had the watch less than 2 years they will most likely take it under warranty and correct the issue, at the very least they have equipment to test and diagnose both the watch and strap, although it sounds like your HR strap is fine since you are getting HR on the machines.

New battery needed and fitted to a Polar heart rate monitor


This is really easy to do yourself. Get a CR1632 battery, unscrew the four screws on the back (dont tip the watch as there is a small spring in the watch), unclip the metal band holding in the old battery noting the way 'round the battery is in (minus side up), pop in new battery and push clip back down, when re-fitting the back make sure the spring mentioned earlier lines up with the white sticker with a hole in it on the inside of the watch back, screw down the back. After you have re done all your settings you may need to re-aquaint the watch with the strap, to do this put on the watch and strap, set the heart monitoring going, bring the watch up close to the 'Polar' logo on the chest strap until the time is displayed, should now be all set up.

Polar F4 monitor is reading about 30bpm less than actual


Check that the case back is on the right way. A spring sticking out of the watch mech needs to line up with a hole in the white sticker on the inside of the case back, I think this is the receiver aerial.

How do I change the battery?


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/

Which way round does the battery go in a Polar FS1 HRM watch?


Battry must go - (minus) into the movement and +(plus) facing up. As battery replacement must be done with watch upside down, you must see the +(plus) on battery when it is inserted into the movement and the fit the contact over it.

Do not forget to rate, please.

Timex M515 Heartb Rate Monitor in correct readings


I´m experienced the same problem of incorrect readings after a long time without use. I cleaned the rubber parts of the chest strap with soap and water, than I use some silicone grease or other silicon liquid to keep the rubber hydrated. Make a careful cleaning in the contact area between the rubber and the plastic parts, the fissure in these area use to be full of "sweat dust".

Can Link watch with Heart Monitor


If you can't link the hrm do as detailed in the following link If you press all four buttons of your Nike HRM it will reset. Next time you go to "RUN" mode, it will show "HRM LINK" error. You will now need to "hard reset" the unit. Nike made a late change to add a "hard reset" to the chest strap. To re-link (re-initialise) the watch you'll need to open the battery door on the chest strap, and use a paper clip (or the equivalent) to push the small gold button in the battery area. There should be a small sticker in the battery compartment that points to the reset button. The re-initialisation steps for the Nike C10 and CV10 digital HRM's is: (1) reset the watch (2) open the battery door on the chest strap (3) move the watch to RUN mode (4) press the reset button in the chest strap battery area (5) put the battery back in the chest strap (if it's not already in - it's possible to push the button without removing the battery) (6) hold both of the electrode to create a signal (probably not necessary - it usually links immediately). My suggestion is to use a very thin needle and do it with the battery in the hrm. Eventually, Nike will either eliminate the hard reset or update the manual to include this info.
