Press the 'Voice' button and use the numeric keypad to enter the number corresponding to the desired voice. Refer to the keyboard's manual for the list of available voices.
Ensure that the volume is not set too high, as this can cause distortion. Check the connections to any external speakers or amplifiers. If distortion persists, the keyboard may need servicing.
Yes, the Yamaha PSR-18 can be powered using six 'D' size batteries. Ensure the batteries are inserted correctly and are fresh for optimal performance.
