Zenith Flash-Matic Seattle area

I know they had problems with early garage door openers that were sound activated.
The next door neighbor would honk his horn and your garage door would open!

I didn't realize they had problems with the ultrasonic type tv remotes though as they used them for quite a while.

I remember running across a zenith portable with remote and thought it was pretty neat.
The motor that changed the channels was very noisy though.
Are the channel changer motors supposed to run at idle continuously?
