Volume And Loudspeaker Control; Offline Profile - Nokia N78 User Manual

Warning: When you use the
headset, your ability to hear outside
sounds may be affected. Do not use
the headset where it can endanger
your safety.
Some headsets come in two parts, a
remote control unit and headphones.
A remote control unit has a
microphone and keys to answer or
end a phone call, adjust the volume,
and play music or video files. To use the headphones
with a remote control unit, connect the unit to the
Nokia AV Connector (3.5 mm) in the device, then
connect the headphones to the unit.
If a headset does not include a microphone, for
handsfree phone calls, use such a headset with a
compatible remote control unit or the microphone of
the device.
When using certain headset enhancements, to adjust
the volume during a call, use the volume key in the
device. Some headset enhancements have multimedia
volume controls that are used to adjust the volume
only for music or video playback.
Do not connect products that create an output signal
as this may cause damage to the device. Do not connect
any voltage source to the Nokia AV Connector.
When connecting any external device or any headset,
other than those approved by Nokia for use with this
device, to the Nokia AV Connector, pay special attention
to volume levels.

Warning: Do not hold the device near your ear
when the loudspeaker is in use, because the volume
