A 3.5mm
Headphone Socket
located on the left hand side of your radio
is provided for use with either headphones or an earpiece. 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.
IMPORTANT:
Excessive sound pressure from earphones and headphones
can cause hearing loss.
