Solution
• Is the power cable connected to the outlet? Connect power cable to the outlet.
• Has the power cable's plug come off? Check whether or not the plug is properly attached to the product.
• Is the cartridge's protector still in place? Remove the cartridge's protector.
• Is the tonearm in the lift position? Lower the tonearm.
• Are the function settings and input for connected equipment (amplifier, etc.) selected correctly? Check
whether the settings for the connected equipment are correct.
• Is the stylus damaged? Check the stylus and replace it, if necessary.
• Is the stylus placed correctly on the body of the cartridge? Check the cartridge and adjust it, if necessary.
• Are the setting positions for the pre-amplifier selector switch correct? Check that the pre-amplifier settings
are correct, noting the following common problems and their causes:
- If there is no sound, or if the volume is not loud enough, the product is set to the "PHONO" position
and connected to the amplifier's AUX/LINE input.
- If the volume is too loud or is distorted, the product is set to the "LINE" position and connected to the
amplifier's PHONO input.
• Is the tracking force set too heavy? Adjust the tracking force.
• Is the tracking force set too light or too heavy? Adjust the tracking force.
• Is the anti-skate set improperly? Verify anti-skate is set for same value as cartridge tracking force.
• Is the record warped? Check the record.
• Is the record scratched? Check the record.
• Is the product picking up excessive vibrations from the floor, surfaces of the walls, or nearby speakers?
Decrease the vibrations or mount the product on a surface that is not subject to the effects of vibrations.
• Is the product mounted on an unstable surface? Check whether the surface on which the product is
mounted is suitable.
• Is there dust on the cartridge's stylus tip? If dust is stuck to the stylus tip, clean it with a commercially
sold brush.
• Are the speed settings for the product correct? Use the platter speed buttons to select the correct speed
for the type of record being played.
• Is variable pitch engaged? Depress quartz button or return pitch adjust slider to center detent position to
engage quartz lock.
• If the LED next to the pitch adjust slider center detent position remains blue when the slider is moved,
quartz lock is engaged. Depress the quartz button to disengage the quartz lock and activate variable
pitch. The LED should turn off.
• Excessively bright or fluorescent light interferes with strobe indicator. Hold hand, record jacket, etc. over
strobe indicator to shield it from bright light.
• Is the ground line connected correctly? Make sure the ground line is properly connected.
• Is the headshell attached to the tonearm firmly? Make sure the locking ring is tight.
