Why is my Yamaha YDP-121 headphone volume low?

If you're experiencing low headphone volume on your Yamaha Musical Instrument, please note that the [MASTER VOLUME] control adjusts the headphone volume when headphones are connected to the PHONES jack. Adjust the master volume to increase the headphone volume.
