Troubleshooting Problem Possible Cause and Solution When the instrument is turned on or off, a popping sound is temporarily produced. This is normal and indicates that the instrument is receiving electrical power. When using a mobile phone, noise is produced. 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. There is no sound even when the keyboard is played or when a Song or Style is being played back. 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. Check the Local Control on/off. (See page 63.) Playing keys in the right hand area of the keyboard does not produce any sound. When using the Dictionary function (page 58), the keys in the right hand area are used only for entering the chord root and type. • The volume is too soft. • The sound quality is poor. • The rhythm stops unexpectedly or will not play. • The recorded data of the Song, etc. does not play correctly. • The LCD display suddenly goes dark, and all panel settings are reset. The batteries are low or dead. Replace all six batteries with completely new ones, or use the optional AC adaptor. The Style or Song does not play back when Is External Clock set to ON? Make sure External Clock is set to OFF; the [START/STOP] button is pressed. refer to "External Clock Settings" on page 64. Make sure that the Style Volume (page 55) is set to an appropriate level. The Style does not sound properly. Is the Split Point set at an appropriate key for the cords you are playing? Set the Split Point at an appropriate key (page 48). Is the "ACMP ON" indicator showing in the display? If it is not showing press the [ACMP ON/OFF] button so that it does show. Not all of the voices seem to sound, or the sound seems to be cut off. The instrument 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 footswitch (for sustain) seems to produce the opposite effect. For example, pressing the footswitch cuts off the sound and releasing it sustains the sounds. 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. The sound of the voice changes from note to note. This is normal. The AWM 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. The ACMP ON indicator does not appear Always press the [STYLE] button first when you are going to use any when the [ACMP ON/OFF] button is pressed. style-related function. The harmony doesn't sound. The method of sounding the harmony effect (01-26) differs depending on the selected type. For Types 01-05, turn the Auto Accompaniment on and play it by pressing a chord in the auto accompaniment section of the keyboard, then play some keys in the right-hand side to get the harmony effect. For Types 06-26, turning the Auto Accompaniment on or off has no effect. However, it is necessary to play two notes simultaneously for Types 06-12. The part indications, such as Right, Left and Both Hands, do not appear-even when pressing the [R] or [L] buttons for the Lesson. Make sure that you are not pressing the [R] or [L] buttons while the Song is playing. If you press one of the part buttons while playing the Song and before starting the Lesson, these buttons serve to mute the corresponding Song tracks. Stop the Song first, then select the desired part and start the Lesson. 68 PSR-A300 Owner's Manual 66
