Headphone socket
A 3.5mm Headphone Socket located on the rear of your radio is provided
for use with headphones. Inserting a plug automatically mutes the internal
loudspeakers.
Please be aware that the sensitivity of headphones can vary widely. We
therefore recommend setting volume to a low level before connecting
headphones to the radio. It is also recommended to reduce the volume
before unplugging your headphones.
IMPORTANT: Excessive sound pressure from earphones and headphones
can cause hearing loss.
