2. SERVICE PROCEDURES AND ADJUSTMENTS

1. POWER SUPPLY VOLTAGES
Before connecting the unit to an AC outlet, check
whether it is set for the local AC voltage. The turntable
may be set to operate at either 110~ 120V or 220 ~
240V. The voltage selector is under the turntable. In
almost all cases, the frequency is preset to 50 Hz.

In order to comply with a frequency of 60 Hz, replace

the motor pulley with the extra one included in the V""399 59'9
accessories. Use a small-size standard screwdriver. During

this operation, set the speed selector to the 33 rpm

position and be sure that the top surfaces of the pulley

and belt guide are even as shown in the diagram of right
