Volume and loudspeaker control
To increase or decrease the volume level, when you have
an active call or are listening to a sound, press and hold

nearby. Sound applications use the loudspeaker by
default.
Warning: Listen to music at a moderate level.
Continuous exposure to high volume may damage your
hearing. Do not hold the device near your ear when the
loudspeaker is in use, because the volume may be
extremely loud.
To locate the loudspeaker, see ‘Keys and parts’ in the
Quick start guide.

Before connecting a device other than original Nokia
headphones to the headphone connector of your Nokia
N91, adjust the volume level to less than half to prevent
sound distortion or damage to the external device. Then
you can readjust the volume to the appropriate level.
With some headsets you can only adjust the volume with
the volume keys of the headset. If you use the volume keys
of the device, the volume changes only after you detach
the headset.
