  There are several potential reasons for the lack of sound from your Casio Electronic Keyboard: * There may be a power supply issue. Ensure the AC adapter is correctly attached, the batteries are properly installed with the correct polarity (+/–), and that the batteries are not depleted. * The power might not be turned on. Check the POWER/MODE switch to ensure it is in the ON position. * The volume could be set too low. Adjust the MAIN VOLUME slider to increase the volume. * The POWER/MODE switch might be set to CASIO CHORD or FINGERED. Normal play is not possible in these modes; switch it to NORMAL. * LOCAL CONTROL may be turned off. Turn LOCAL CONTROL on.

  If your Casio Electronic Keyboard song playback cuts out during SMF play, the data may be fragmented. You can try the following: * Save the data under a different name using the “save as” function without deleting the original data. Then, try using the newly saved data. * If the data was saved from another location, format the card (this will erase its contents) and save the data to the card again. Then, try using the newly saved data.
