(1)	Do not connect input signals having a higher voltage than that listed on an input jack. Although all the input jacks listed on the synthesizer panel are equipped with protection circuitry, you should always pay careful attention to the permissable voltage ratings displayed. This will ensure stable and reliable operation. When in doubt, check with the volt meter.
(2)	When connecting the output signal from the MS-50 to external equipment, make sure that the input impedance is at least 10kOhms.
(3)	Only use the correct AC supply voltage. If the MS-50's power cord is plugged into an AC outlet having 90% or less than the correct voltage, the signal-to-noise ratio will suffer, and the synthesizer modules will not operate with optimum stability. If you have any reason to think that the power supply voltage is too low, have it properly checked before turning on the MS-50's power switch.
(4)	Only use standard phone plugs for the input and output jacks.
