Key functions and features
This phone holds the next step in imaging for
Sony Ericsson products. And a great one. The evo-
lution of mobile communications towards imaging
will greatly increase the scope for new applications
and services. In the area of multimedia in mobile
phones, Sony Ericsson can show its vast experi-
ence in consumer electronics and entertainment –
music, pictures and games – as well as its mobile
technology leadership.
System
D750i supports GSM (Global System for Mobile
Communications), GSM + EGSM 900/DCS 1800/
PCS 1900, GPRS (General Packet Radio Service),
Multislot class 10 (4+2) and HSCSD (Highspeed
Circuit Switched Data).
System connector
The new system connector called Fast port, is
smaller, faster, more versatile and easier to use
than the former system connector. For example,
different accessories can be connected in series,
and you can have a phone conversation and
upload music or synchronize simultaneously.
Improved battery capacity
The phone has top class talk- and standby time.

mer and LI-lon (built-in)
Standby time: up to 400 hours
Talk time: up to 9 hours
Direct music button
Music is only one click away.
Press the direct music button on
the side of the phone and listen to
your favourite tunes instantly
without having to move between the menus. By
default the direct music button is set to access the
most recently used feature such as the Media
player or FM Radio.
2.0 Mega pixel camera
With the 2.0 Mega pixel camera
which includes digital zoom and
auto focus, taking pictures
becomes easy and fun. The hori-
zontal user interface and the active lens cover adds
extra quality to the camera experience.
Video clips
Taking a picture or recording a
video clip and sending it as part of

Sony Ericsson’s constant ambition of making prod-
ucts easier to use, has had a great outcome:
QuickShare™.
QuickShare is the fastest, easiest and smartest
ever way to share images. With just a few clicks,
moments can be captured with the integrated cam-
era and be shared with friends! For example, to
send a picture message with text and an attached
image or video clip takes only 4 steps. Capture an
image, press send, add text and press send again
to add a recipient.
There is more to QuickShare than sending images
with a picture or email message. QuickShare is
about ease of use for all imaging features. Images
can be shared phone to phone, with Bluetooth™,
across the room or between a phone and other
paired devices such as PDAs, computers or print-
ers. For example, it would give the user the possi-
bility of printing a picture directly from the phone
using a Bluetooth enabled HP printer.
Bluetooth™ Media Center MMV-
200
The MMV-200 is a Bluetooth hub that supports
streaming media such as images, video-clips and
music and can be used with a TV or a stereo. It has
support for mega pixel images and lets the user
transfer music to supported stereo equipment.
Sharing of mega pixel images and video clips via
Bluetooth and the phone’s Memory Stick becomes
easy and fun. The phone works as a remote control
when the MMV-200 is in use. Will be offered as a
supporting accessory.
Full graphic 262k colour screen
The large 1.8 inch colour screen,
176 x 220 pixels, enhances viewing,
facilitating high-quality multimedia
and entertainment.
User Interface (UI)
From standby, the phone features a
user interface built on the “desk-
top” concept, which is widely used
in many computer operating sys-

tems. From here, navigation between different main
functions in the phone is done by selecting one of
the 3D icons which is represented.
Activity menu
Get direct access to new events, bookmarks and
shortcuts. By pressing the navigation key upwards
in standby mode the user can easily access the
activity menu and handle missed calls, new text
and picture messages, task reminders, shortcuts
and get quick access to favourite Internet book-
marks. It is also possible to get a direct overview of
applications that are running in the background, for
example the media player or the FM radio.
Sound
You can listen to sound in the phone via the
speaker (earpiece), the loudspeaker, the high-qual-
ity stereo headset or other compatible accessories.
Media player
The Media player converts the
phone into a portable MP3, MPEG4,
H263 player. Play music and video
clips, streamed or downloaded. The
folder system enables you, for example, to organ-
ize your favourite songs into groups and create
simple playlists. A play and pause function has
been added.
Radio
The new RDS (radio data system) FM
radio is built-in and offers instant and
easy access to FM radio channels.
The user also has the possibility of using it as an
alarm clock signal.
The radio can be listened to with the portable
handsfree accessory (Stereo Headset) or via the
internal speaker. With the radio, up to 20 favourite
channels can be stored with the preset function.
The portable handsfree needs to be connected at
all times when listening to the radio, since it works
as an antenna.
The RDS function brings you information directly to
the display which is sent out by the currently tuned
in radio station.
Streaming and downloading
You can view videos and listen to music that you
find on a web site by streaming them to your
phone. By streaming media such as audio and
video clips, multimedia is available in realtime with
minimal downloading or waiting time. This means
that you can start to listen to the music or view a
video clip before the complete file is downloaded
to the phone. Media can also be downloaded and
saved in the phone memory and then used with the
Media player. Media such as audio files, video clips
or slide shows can be played back at any time.
Sony Memory Stick PRO Duo™
The D750i supports Sony Memory
Stick PRO Duo™ and the Memory
Stick Duo™. The user can store dif-
ferent kinds of content (pictures,
audio, video clips etc.) on the Memory Stick, and
transfer the content to other Sony Memory Stick-
compatible consumer products, for example Sony
digital cameras, camcorders, portable music play-
ers, TVs, photo printers and computers.
USB mass storage
A USB (Universal Serial Bus) cable
is included in the box. The USB
cable allows easy connection of the
mobile phone to a computer. To be
able to use the USB cable with the phone, driver
routines must be installed on the computer. The
drivers will be available on the CD in the kit or can
be downloaded from
www.SonyEricsson.com/support.
When the user connects the phone to a computer
via the USB cable, the Memory Stick storage in the
phone will appear as a drive on the computer. The
user can then drag and drop any supported infor-
mation to complete a transfer.

MMS
Reacting to the enormous popular-
ity of mobile phone messaging,
Sony Ericsson has incorporated the
latest messaging standard, along
with a colour display for an enhanced imaging
experience.
With MMS, there are many interesting applications
to subscribe to, for example, stock information,
movie trailers and weather reports.
Content such as music, video and
images may be previewed before
purchase. A unique direct-link to
download music, video, games,
themes and images, which is easy to use and
promises you best-selling content for mobile
download. By selecting PlayNow™, you can, for
example, go straight to a live list of Top Music Hits.
Content formats that are supported
All formats that are supported in the phone will be
possible to download. Music, video and images
may be previewed before purchase. The music for-
mat is MIDI, MP3 or WAV (Polyphonic 24 voices or
more).
How the service works
This service is owned by Sony Ericsson or hosted
by Sony Ericsson for a network operator. The
PlayNow™ or other premium content is maintained
and managed, for example by Sony Music or Sony
Pictures. The content on offer can easily be suited
to a specific region or operator.
Implementation costs for network operators are
minimal and server communication is based on
existing, well-established standards. Sony Ericsson
offers first or second line support according to the
agreement on hosting a white label service or not.
High level co-operation is available for the design,
look and feel, of content management.
Operator benefits
This service is aimed at providing quality and quan-
tity revenue for network operators. This is truly an
ARPU (Average Revenue Per User) driver with low
costs for operators. The process involves:
• Downloading a list
• Previewing content
• Choosing content
•Buyingcontent
Note: The availability of this unique application is
limited to specific markets, where relevant infra-
structure and agreements have been set up.
Other technical details
Security - Server communication is protected by
TLS (Transport Layer Security) and SSL (Secure
Socket Layer).
Forward lock - Content cannot be exchanged with
other devices by the user, it is limited to use or
delete.
Java 2, Micro Edition (J2ME™)
Download extra content with Java™, for
example, new information- and enter-
tainment-based applications. This gives
users a chance to personalize the func-
tions and features in their phones, and
developers the opportunity to create new
applications.
Gaming
Gaming is already a very popular
feature in mobile phones, and with
Advanced Java, users can add
new games and skill levels to fur-
ther enhance the entertainment value of
Sony Ericsson phones.
3D Games
Java 3D gaming software intro-
duces and supports cutting-edge
3D graphics. Audio developments
such as 40 tones polyphonic
sound and force feedback provide a much richer
experience. With operator support, there is the
possibility for multiplayer games to play against
friends. The large 1.8 inch TFT screen adds to a
lasting gaming experience. Downloading graphic
intensive games, matching up to the size of the
built-in memory, is also possible.

Bluetooth™ wireless technology
Using built-in Bluetooth™ wireless
technology, communication with
other Bluetooth devices is sup-
ported via a radio link. Unlike infra-
red, Bluetooth wireless technology is not
dependent on line-of-sight communication.
Several devices (simultaneous Bluetooth connec-
tions) can be connected to the phone using Blue-
tooth wireless technology up to 10 metres away.
For example, the phone can be answered with a
Bluetooth headset, when it rings and the user can
send images to another phone at the same time.
Several mobile phones can take part in a Bluetooth
supported game and the phone and a computer
can exchange data such as images, video clips,
business e-cards, music files and calendar data.
Copyright protection – DRM
DRM (Digital Rights Management) features the
rights and copy protection of downloaded content
(audio, pictures, music tones, video, entertainment
features such as games etc.).
Content-based services have great market poten-
tial, and to encourage this, Sony Ericsson plans to
support DRM in all future multimedia products.
Sony Ericsson regards DRM as a key enabler for
content-based services, and is active in supporting
the ongoing standardization work of the OMA
(Open Mobile Alliance). Furthermore, any additional
market requirements for DRM will be monitored.
Design features
Ergonomics and balance
The phone strives for a perfect balance in your
hand. Ergonomics link together with design.
Display and keypad areas
The 1.8 inch display area accommodates relatively
large keys on the keypad area.
The keys are aligned in a vertically grouped form.
The display and key areas are designed with a
sophisticated metal look.
Front
It is possible to customize the Internet button area,
which is placed just beneath the display.
The circular background form around the naviga-
tion key is designed to complement the circular
form of the camera on the camera front.
The Memory Stick slot is placed beneath the key-
pad.
Battery cover
The battery cover is designed to horizontally slide
into place whilst locking the battery in the battery
housing.
