When using a mobile phone, noise is produced. Using a mobile phone in close proximity to the PSR-275/273 may produce interference. To prevent this, turn off the mobile phone or use it further away from the PSR-275/273. There is no sound even when the keyboard is played or when a song 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 or PC Mode on/off.

Press the [STYLE] button to enable style operations. The style or song does not play back even when Check the External Clock on/off. (See page 57.) pressing the [START/STOP] button. The style or song does not sound properly. Make sure that the Style Volume or Song Volume (page 39) is set to an appropriate level. When playing back one of the Pianist styles (#93 #100), the rhythm cannot be heard. This is normal. The Pianist styles have no drums or bass - only piano accompaniment. The accompaniment of the style can only be heard when accompaniment is set to ON and keys are played in the auto accompaniment area of the keyboard. Not all of the voices seem to sound, or the sound seems to be cut off. The PSR-275/273 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. A strange "flanging" or "doubling" sound occurs when using the PSR-275/273 with a sequencer. (This may also sound like a "dual" layered sound of two voices, even when Dual is turned off.) When using the style with a sequencer, set MIDI Echo (or the relevant control) to "off." (Refer to the owner's manual of your particular device and/or software for details.) 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. 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. 70
