Optical Heart Rate Monitor not lighting up/switching o

Former Member over 9 years ago

Hi,
I have recently purchased the 235 watch and was looking forward to tracking my heart rate while running.

The heart rate monitor didn't bring/track any results on my first run and noticed none of the green lights were lighting up on the underside of the watch. I have checked the heart rate settings and it's set to auto.

Does anyone have any ideas as the watch is brand new and was working when I first opened it and the green lights were on. It looks like the heart rate monitor is not switched on.

Thanks

I guess you have already checked the settings?
Select Menu > Settings > Heart Rate Monitor > On/Off.

Did you try to reset it?

If the device stops responding, you may need to reset it.

NOTE: Resetting the device may erase your data or settings.
Hold power button for 15 seconds.
The device turns off.

Hold power button for one second to turn on the device.
