255 elevation is incorrect

9787301 18 days ago

My 255 Music watch has started having major issues with elevation over the last 2-3 months. I have attempted different satellite settings and I have started to calibrate it prior to each workout but my readings are still wildly incorrect. All my workouts end up with elevation gain of 10,000 to over 100,000 feet which is simply not possible. Any tips to fix this?

Do you have the barometric sensor in "automatic" mode so it uses it as an altimeter or barometer based on its own logic?

Aside from that, I'm not sure there is much you can control. Do you swim with the watch? It could be the sensor port is dirty and doing the soak maintenance will clean it out. Or it could be the sensor is going bad and the only remedy would be a replacement watch...

My 255 music has been giving me the same problem for a month. The problem hasn't been fixed despite my attempts to clean the barometric sensor port as described in the user manual.

Same - I've tried calibration and cleaning the sensors. To no avail.

I've tried to do the recomended maintenance (calibration, cleaning the port sensor at the back of the watch with no changes at all). Any other solution?
