Headphone Socket; Line Out Socket; Usb Socket For Software Upgrades - Roberts Gemini RD-45 User Manual

Headphone socket

A 3.5mm Headphone Socket located on the rear 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.
To prevent possible hearing damage, do not listen at high
volume levels for long periods.

Line out socket

A 3.5mm Line out socket located on the rear of your radio is provided
for connecting the audio signal to an external amplifi er. Inserting a plug
into the line output socket will not mute the internal loudspeaker. Set the
volume control to adjust the speaker volume level as required.
USB socket for software upgrade
In the event that any software update is made available for your radio
