There is a buzz in my ears

Hello new here just getting back into vinyl.  And I recently picked up a few Kenwood components.
KM-207 -Power  amp
KT-87 -Tuner
KC-207 -Control amp.
RC-70-IR remote control
Fluance -RT83 .. delivering this week..woohoo!!
Question I have is ....Whenever I use the remote whether it be for volume , station select, source etc..
it creates a buzz like a radio station is not coming in clear.. out of my 49yr existence I have NEVER come across this .. I am out of ideas.  Not a big deal but rather an annoying inconvenience.. 
anybody have any ideas what is happening??

Thanks for your suggestions
