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
or on the left side of the device.
The built-in loudspeaker allows you to speak and listen to
the phone from a short distance without having to hold the
phone to your ear, for example, having it on a table 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.
To use the loudspeaker during a call, start a call, and select
Options > Activate loudsp..
To turn off the loudspeaker when you have an active
call or are listening to a sound, select Options >
Activate handset.
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.
