High pitched sound

[Gurman]

I don’t know why but I keep hearing high pitched sounds that I think are coming from the watch. What is this?

The only sound you should hear from your Alta HR is the vibration buzz. As far as I am aware it doesnt have the means to make any other sounds. If it is coming from your tracker then I'd suggest you contact Support (link in my signature ).

I plugged in my Flex 2 tracker tonight and heard a high pitch very faint whistling/ringing? sound. To make sure it was actually my tracker, I unplugged it and the ringing stopped. Plugged it back in and it started again. Haven’t heard this sound before. It is actually very annoying. Annoying enough that I can’t charge it on my headboard as I usually do.

I have a Fitbit ionic. I also hear the high pitched noise when I plug it in. I thought maybe it was the Bluetooth. It's annoying though

I have a fitbit versa and I had never heard the sound before. I usually charge my versa on my desk but I had to move it out of my room so I couldn't hear the high pitched sounds because it hurts my ears. It sounds like this really high ringing sound of a sort. I just want to know if I can make it stop so my versa can charge in my room not the living room.

Have the same issue,

the noise is extremely high pitch and quite noticeable. Absolutely irritating😞
