Maintenance
There are no user serviceable parts inside the M60C.
One or two days after installation check the tightness of the fixing screws of the loudspeaker drivers. These screws may loosen slightly in shipping or with extremes of temperature or humidity, and the speaker will not sound at its best with them loose. Do not over tighten them. It is worth checking these screws after transit or extended periods of loud playing.
The electronics do not need routine maintenance.
The audio sockets are gold plated and, where gold plated phono sockets are used, there should be no need to clean the contacts. Other phono plugs should be unplugged and replugged once a year. Some proprietary contact cleaners may be used to advantage, but you should seek the advice of your dealer.
