8.1 MOUNTING

The MDC-360 is intended for rack mounting. For maximum operating ease it
should be mounted at approximately eye level. If the MDC-360 is mounted in a
rack containing other heat generating equipment, care should be taken that there is
adequate ventilation to assure that the ambient temperature does not exceed the
MDC-360’s ambient temperature rating.

The MDC-360 was designed for maximum noise
