DTMF tones
DTMF tones or touch tones are the tones that sound when you
press the keys on your phone keypad. You can use touch tones
for many automated dial-up services such as banking and
airlines or for entering your voice mailbox number and password.
To set the key tone length, select Menu > Settings & Tools >
Call Settings > DTMF Tones. Select Normal to send out a tone
for a fixed period of time no matter how long you press the
key or Long to send out a continuous tone for as long as you
keep the key pressed.
■ Bluetooth
Bluetooth technology connectivity enables wireless connections
between electronic devices and can be used to send and
receive images, texts, gallery files, voice recordings, video clips,
notes, and more. It can also be used to connect wirelessly to
products that use Bluetooth wireless technology, such as
computers. You can synchronize your phone and your PC
using Bluetooth connectivity.
Since devices with Bluetooth connectivity communicate
using radio waves, your phone and the other device do not
need to be in direct line-of-sight. The two devices only need
to be within 10 meters (30 feet) of each other. The connection
can be subject to interference from obstructions such as
walls or other electronic devices.
This device is compliant with Bluetooth specification 1.1,
supporting the following profiles: HSP V1.1 (headset profile),
HFP V1.0 (handsfree car kit profile), and DUN V1.1
(dial-up networking).
To ensure interoperability between other devices supporting
Bluetooth technology, use Nokia approved enhancements for
this model. Check with the manufacturers of other devices to
determine their compatibility with this phone.
