Troubleshooting Problem When the EZ-30 is turned on or off, a popping sound is temporarily produced. • The volume level is low. • Tonal quality has degraded. • Recorded songs are not played correctly. • The display indication is turned off suddenly and the panel settings are reset. Noise is produced from the EZ30. There is no sound even when the keyboard is played or when a song is being played back. The effects (Reverb/DSP/Harmony) are not applied. The auto accompaniment doesn't turn on, even when pressing the [ACMP ON/OFF] button. Not all of the voices seem to sound, or the sound seems to be cut off. Auto accompaniment is not played correctly. The polarity of the footswitch is reversed. Possible Cause and Solution This is normal and indicates that the EZ-30 is receiving electrical power. The battery voltage is low. Replace all six batteries with new ones, or use the AC adaptor. When using a mobile phone, noise is produced. Using a mobile phone in close proximity to the EZ-30 may produce interference. To prevent this, turn off the mobile phone or use it further away from the EZ-30. Check that nothing is connected to the PHONES/OUTPUT jack on the rear panel. When a set of headphones is plugged into this jack, no sound is output. When using the Dictionary function (page 58), the keys in the right hand section are used only for entering the chord root and type. Each effect (Reverb/DSP/Harmony) is turned off. Select a type for each effect. (See page 48, 49, 50.) When playing back one of the Pianist styles (#97-#106), the rhythm cannot be heard. The Pianist styles have no drums or bass - only piano accompaniment. The EZ-30 is polyphonic up to a maximum of 32 notes. If the Dual voice or Split voice is being used and a style or song is playing back at the same time, some notes/sounds may be omitted (or "stolen") from the accompaniment or song. The accompaniment volume setting is low. Refer to page 61 to raise the volume level. The auto accompaniment split point is set incorrectly for the played chords. See page 44 to set a correct split point. You turned on the power to the EZ-30 while pressing the footswitch. Turn the power off, then turn it on again without pressing the footswitch. 83
