Relays on the Yaesu 980
 

I keep hearing about cleaning the contacts on the relays on the Yaesu 980.
I have an intermittent problem that I'm not sure if it's a relay or not.
But because of the age of the radio, I figured it might not be a bad idea to
pop off the plastic top and clean the contacts. The problem is I don't see
an easy way to get inside the plastic cover. I don't want to spray anything
inside the relay, I would rather burnish the contactss. Anyway, looking for
any words of wisdom, So far, I have been leaving sleeping dogs lay.
