The Nº390S is designed for continuous operation—hence the

standby button on the front panel rather than a power button.

However, a rear panel power switch is provided for your convenience

should you want to disconnect the unit from the AC mains (as

when taking a vacation, for example).

Drawings are included in this manual to facilitate special

installations and custom cabinetry (see Dimensions on page 61).

Operating Voltage &

Frequency

The Nº390S CD Processor is set at the factory (internally) for 100V,

120V, 200V, 220V, or 240V AC mains operation as appropriate for

the country in which it is to be sold. Make sure that the label on

the rear of the Nº390S (adjacent to the power cord) indicates the

correct AC operating voltage for your location, as attempting to

operate the Nº390S at an incorrect voltage can damage the unit.

The Nº390S CD Processor is also set at the factory for operation

on either 50 or 60 Hz AC line frequencies, as appropriate for the

country in which it is to be sold. It will not operate if it senses an

incorrect line frequency.

Warning! Neither the voltage nor the line frequency setting may be

changed by the user. There are no user serviceable parts inside

the Nº390S. Only qualified, authorized service personnel may

open the Nº390S CD Processor, as hazardous voltages exist

within the unit.

If the AC mains voltage or frequency indicated on your Nº390S is

incorrect, please contact your local, authorized Mark Levinson

dealer or distributor.

The Nº390S can easily be powered by a normal 15-ampere AC

mains line. If other devices are also powered from the same AC

line, their additional power consumption should be taken into

account.
