OptimumOnline → How do I check signal level on a SA 8300?

I am wondering if I have sufficient signal strength going into my SA 8300. Is there a test/diagnostic mode that reports this value on-screen?

Thanks SixSense for the fast response. That link indicates I should try "pressing and holding the front-panel CENTER key (aka Bullseye, between ch+ - and vol + -)". Those ch and vol keys are configured in a diamond shape but there are no keys in the center. There is no obvious "bullseye". Those instructions probably apply to earlier models. Any ideas on how to bring up the diagnostic screens?

Thanks!

I found the answer.... "Press and hold the Select button on the front of the unit until the Mail light starts to flash, then press the INFO button."

Now I will try to figure out all those diagnostic pages
