Practical Considerations
P H Y S I C A L
The case of the MX250 CCEP is fully enclosed to prevent the entry of foreign material and to shield the internal circuitry from most outside
electromagnetic fields.To prevent the circuitry’s picking up hum from inadequately shielded transformers, mount the MX250 CCEP at least two
inches from any power amplifier. Computer monitors, motorized devices, and some other gear may emit strong hum or electromagnetic fields
also, so exhibit care when mounting the MX250 CCEP near them.
Convection currents from power amplifiers and other such heat-producing equipment could cause the MX250 CCEP to run hotter than it
should, perhaps eventually causing premature failure of the electronic components and/or power supply. Make sure there is adequate
ventilation in the equipment rack – use fans if there is any concern.
E N V I R O N M E N T A L
As with all electronic equipment, avoid using the MX250 CCEP in damp or excessively humid conditions. In outdoor applications, protect the
unit from rain and precipitation or any other dampness. If some mishap causes the unit to get wet or damp, dry it out thoroughly before using
it again.
C L E A N I N G
You can clean the exterior of the MX250 CCEP with a slightly damp cloth. Use a small amount of mild detergent or cleaning fluid if necessary.
Do not use petroleum spirits, thinners, or other solvent cleaners – they might seriously damage the finish.
