Before You Play
Listening through Headphones
You can use headphones to enjoy the HP207 without disturbing those around you, such as at night. Since the HP207 has two headphone jacks, two people can also use headphones simultaneously. If you�re using only one set of headphones, you may connect them to either of the two headphone jacks.

Cautions when Using Headphones
� To prevent damage to the cord�s internal conductors, avoid rough handling. When using headphones, mainly try to handle either the plug or the headset. � Your headphones may be damaged if the volume of a device is already turned up when you plug them in. Minimize the volume before you plug in the headphones. � Excessive input will not only damage your hearing, but may also strain the headphones. Please enjoy music at an appropriate volume. � Use headphones that have a stereo 1/4� phone plug.
