RS450/100 High pitch sound when charging?

Hi,

I have a RS450/100 that is about a year old and started to make a very high pitch sound while charging. It's not excessively loud but very noticeable nonetheless. It started doing this in the last month or two.

Is this something to worry about, as a prelude to future issues, and have it looked at by a certified installer or ignore just it?

Regards,

Ingo
