Troubleshooting 11 Problem Possible Cause and Solution GENERAL OPERATION The sound is not heard for about 10 seconds after turning the power on. This is normal; the Electone takes a while to start up. A click or pop is heard when the power is Electrical current is being applied to the instrument. This is normal. turned on or off. A cracking noise is sometimes heard. Noise may be produced when either an electrical appliance is turned on or an electric power tool (such as drill) is used in the proximity of the Electone. If this occurs, plug the Electone into an electrical outlet located as far as possible from the device that seems to be the source of the problem. Interference from radio, TV, or other sources occurs. This is caused by the proximity of a high-power broadcasting station, an amateur ham radio setup or a mobile phone. Noise is heard from the instrument's speakers or headphones when using the instrument with an application on an iPhone/iPad. When you use the instrument along with an application on your iPhone/iPad, we recommend that you first set "Airplane Mode" to "ON" then set "Wi-Fi" to "ON" on your iPhone/iPad in order to avoid noise caused by communication. The sound of the Electone causes surrounding objects to resonate. Because the Electone is capable of producing powerful bass sounds, resonance may be caused in surrounding objects, such as cabinets or glass windows. To avoid this, relocate the objects or lower the Electone's volume. The sound is too small even when the volume is set to its maximum. • The MASTER VOLUME dial may be set around The minimum position. Turn it clockwise (page 17). • The Expression Pedal may not be pressed down. Press it down with your toe (page 17). • The speaker cord plug is not connected. Securely insert the speaker cord to the Main Unit (page 204). The Pedal Voices do not sound, and the expression pedal does not work. The pedal cord plug is not connected. Securely insert the pedal cord plug to the Main Unit (page 204). The "Connection interrupted; problem occurred in USB device." message is shown and the USB device does not respond. Communication with the USB device has been shut down because of a problem. Disconnect the device from the [USB TO DEVICE] terminal, then turn on the power of the instrument. The Electone panel does not function normally or the content of the memorized data has changed. This happens very rarely. Occasionally, power surges and spikes due to electrical storms or other reasons may cause the Electone to malfunction and/ or alter the contents of memorized data. If this happens, perform the Factory Set operation to reset the Electone. VOICES/RHYTHMS When a key is pressed, two or more Voices sound. Perhaps the Voice of the Voice section 2 sounds as for the Lower Keyboard or Pedalboard. Turn off the Voice of the Voice section 2 in the Voice display, or set the volume setting to minimum after switching to the Voice section 2 (page 36). As for the Upper Keyboard, the Lead Voice may sound in addition to the Voice of the Voice section 2. Turn off the Lead Voice in the Voice display. The pitch may sound excessively high on the Pedalboard and low in the higher registers of the Lower and Upper keyboards. This may occur when you compare the Electone's sounds with that of a piano. Because of the difference of the harmonics structure, the tuning system of the Electone is different from the piano in the higher and lower ranges. Some of the Voices may contain cracking and/or noisy sounds. You may find these mainly in the wind instrument Voices. These are purposely added effects to the Voices to reproduce the characteristics of the wind instruments such as the pipe vibrations, breath noises and squeaks. Appendix 206 ELB-02 Owner's Manual
