YAESU FT857 - RELAY CLEANING & HIDDEN MENU

The Yaesu FT-857 uses relays for a variety of functions. Sometimes the relays will get buildup between their contacts and the radio can start acting odd, or certain functions stop working. Most people go to the reset procedures, but there is another troubleshooting technique that might fix the problem without losing memories and settings - Relay Cleaning. The FT-857 has relay cleaning built-in, and can be accomplished is just a few minutes.

Do you know how it works? I have to do this for the TS-430S that I am restoring. The relays in this version are sealed.
