Troubleshooting Appendix Problem When the instrument is turned on or off, a popping sound is temporarily produced. When the instrument is turned on, power is turned off suddenly and unexpectedly. When using a mobile phone, noise is produced The instrument is automatically turned off even if no operation is done. • The volume is too soft. • The sound quality is poor. • The Style/Groove/Song/Arpeggio stops unexpectedly or will not play. • The recorded data of the song, etc. does not play cor- rectly. • The LCD display suddenly goes dark, and all panel set- tings are reset. • The instrument turns off when a USB flash drive is con- nected. No sound is produced even when the keyboard is played, or a Song, Style, or Groove is being played back. The footswitch (for sustain) seems to produce the opposite effect. For example, pressing the footswitch cuts off the sound and releasing it sustains the sounds. Not all of the Voices seem to sound, or the sound seems to be cut off, when playing the keyboard, Arpeggio, Style or Song or Groove Creator. The sound of the Voice changes from note to note. The keyboard performance and playback of Style/Song/ Groove Creator produces an unexpected or inappropriate sound, and cannot be restored to the normal status. The Style, Song or Groove Creator does not start even when the [START/STOP] button is pressed. The Arpeggio does not start even when the note is pressed with the Arpeggio turned on. The volume of the Style, Song or Groove Creator is too low. The chords played in the left hand area cannot be recognized even when ACMP is turned on. Style parts other than the Rhythm part produce no sound. The ACMP indicator does not appear on the display when the [ACMP ON/OFF] button is pressed. Refer to the "Message List" on pages 42, 77 as required. Possible Cause and Solution This is normal and indicates that the instrument is receiving electrical power. This is normal. If an AC adaptor other than the one specified is used, power may be turned off suddenly and unexpectedly. Using a mobile phone in close proximity to the instrument may produce interference. To prevent this, turn off the mobile phone or use it further away from the instrument This is normal. This occurs due to the Auto Power Off function (page 16). The batteries are low or dead. Replace all six batteries with completely new ones or completely recharged ones, or use the AC adaptor. Check whether a set of headphones or an audio cable is connected to the [PHONES/OUTPUT], or not. When such a connection is made, no sound is output from the speaker of this instrument. (PSR-EW410) Check the on/off status of the Speaker Mute setting (page 48). Make sure to set to OFF. Check the on/off status of the Local Control (page 68). Normally, set this parameter to ON. The polarity of the footswitch is reversed. Make sure that the footswitch plug is properly connected to the SUSTAIN jack before turning on the power. You have exceeded 48 simultaneous notes, which is the maximum polyphony (the maximum amount of notes that can be played simultaneously) of this instrument. If the Main, Dual, and Split Voices are being used along with playback of Arpeggio, Style, Groove or Song, some notes/sounds may be omitted (or "stolen"). This is normal. The tone generation method uses multiple recordings (samples) of an instrument across the range of the keyboard; thus, the actual sound of the Voice may be slightly different from note to note. Using the Knobs can produce dramatic changes in the sound, but may also produce unexpected or undesired sounds. If you want to restore the original, normal sound before being changed by the Knobs, press the [DSP] button to turn DSP off, change the Voice, Style, Groove or Song, or press the [PORTABLE GRAND] button to reset the panel settings. Check the on/off status of the External Clock (page 68). Normally, set this parameter to OFF. Check the volume setting in the Functions (pages 62 and 65). Check the Split Point setting (page 62). Set this to an appropriate value. Check the on/off status of the ACMP (page 26). Make sure to turn ACMP on. Check the on/off status of the [STYLE] lamp. When using a Style, press the [STYLE] button to turn on the [STYLE] lamp. 78 PSR-E463/PSR-EW410 Owner's Manual Appendix
