There is no sound. ee When connecting this unit's analog audio output connectors to the audio input connectors of an amplifier or other equipment, set the PHONO EQ (audio output setting) switch to ON (page 16). Playback is not possible; there is noise. ee Remove the protective cap from the cartridge stylus before using the turntable. ee Reconnect RCA audio cables. ee Fingerprints and dust on a record can cause noise and the sound to skip.

The need for stylus replacement depends on use conditions, but we recommend replacement after about 300 hours of use. ee Place the unit as far away as possible from TVs, microwave ovens and other devices that emit electromagnetic waves. ee Plug the AC adapter into a different outlet. Noise occurs when a record is playing. ee Noise could occur if the tracking force is higher than cartridge's specified value. Readjust the tracking force so that it is the specified value (page 15). The sound is skipping. ee Vibrations will cause skipping. Place this unit in a stable location. ee Clean the record. ee Do not use scratched records. ee Balance the tone arm and readjust the tracking force (page 15).
