Before You Play
Here’s how to adjust the volume of your keyboard playing or the playback volume of an internal song or USB memory song.
If headphones are connected, use the [Volume] slider to adjust the headphone volume.
1. Turn the [Volume] slider to adjust the overall volume.
Adjust the volume while you play the keyboard to produce sound.
Turning the knob toward the right will increase the volume, and turning it toward the left will decrease the volume.
You can adjust the brightness of the HP307’s display.
1. Turn the [Display Contrast] knob to adjust the brightness.
* You may notice something like vertical lines in the screen, but this is due to the characteristics of a liquid crystal display, and is not a
malfunction. You can minimize this by using the [Display contrast] knob to adjust the brightness of the screen.
* The brightness may be affected by the temperature.
