20 Most Recent Polar AXN300 Heart Rate Monitor Watch HRM AXN300 Questions & Answers


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.

Not enough information. Is this a serial number and not a model number? All I was able to locate was a book via basic search. We elect how much time we spend on questions depending on the question. Sometimes it is not cost effective to the site of us to offer extensive research when minimum information provided.
good luck
