A 3.5mm Headphone socket located on the right hand end
of your radio is provided for use with headphones. Inserting
a plug automatically mutes the internal loudspeaker.
Please be aware that the sensitivity of headphones can vary
widely. We therefore recommend setting the volume to a low
level before connecting headphones to the radio.
