Adjusting The Sound's Volume; Adjusting The Brightness Of The Display - Roland HP307 Owner's Manual

Adjusting the Sound's Volume

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.

Adjusting the Brightness of the Display

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.
