D.50HZ TO 60HZ CONVERSION
The standard NST & NT projector is available either as 50Hz sound and
silent or 60Hz sound and silent operations . Conversion from 50 to 60Hz
or 60 to 50Hz can be accomplished by changing the motor pulley only.
To allow the projector to be operated at either 50 or 60Hz sound only,
it is necessary to change the motor pulley and the cam tank pulley (Shut -
ter Pulley). It is now possible to change frequency by simply shifting the
motor drive belt.
