Headphones
Before plugging in or unplugging the headphones, reduce the
volume.
Be sure your headphones have a 3.5 mm (1/8") diameter plug
and impedance between 16 and 50 ohms. The recommended
impedance is 32 ohms.
Plugging in the headphones disconnects the speakers automati-
cally. Adjust the volume using the VOLUME control.
