Sony Ericsson Developer Support
Sony Ericsson offers developers professional tech-
nical support services. The service can be pur-
chased from www.SonyEricsson.com/developer
There are two levels of support, described below:
•The Basic Developer Support is an annual
support service that provides developers with
all the basics to successfully develop world-
class applications for Sony Ericsson products.
With this support contract, developers get
access to high-quality e-mail support with
same-day response and resolution times, five
technical support incidents as well as the ability
to purchase more.
•The Advanced Developer Support is an annual
support service that equips professional devel-
opers with everything they need to successfully
develop world-class applications for
Sony Ericsson products. With this support con-
tract, developers get access to a high-quality e-
mail support with fast response and resolution
times, and up to 50 technical support incidents.
Infrared transceiver
Infrared communication creates a data link
between two communications devices through an
infrared beam of light. On the Z600, this link is used
to connect with desktop computers, PDAs, Sony
Ericsson handheld computers, laptop PCs, other
phones and other hardware supporting the stand-
ard. The Infrared Data Association (IrDA) has set
the hardware and software standards that form the
infrared communication links. The Z600 complies
with the IrMC 1.1 specification, which defines how
mobile telephony and communication devices can
exchange information. In the Z600, the IrMC 1.1
specification is also used for communication via a
cable.
Key benefits of using the Z600 with its built-in infra-
red transceiver:
• True wireless communication
• Low power consumption
• Secure data transmission with the IrDA DATA
standard
• Ability to send and receive e-mail and data on
the connected PC/PDA
• Ability to connect to the Internet or intranet/LAN
from the connected PC/PDA
• Ability to manage the phone book from a PC
• Exchange of business cards and calendar
events with vCard/vCalendar compatible
devices
• Exchange of ring signals between compatible
phones
Connection via infrared
IrDA is a point-to-point communication link
between two infrared ports. The infrared beam has
to be directed towards the target infrared port and
as long as the two infrared ports are within sight
and range, the devices exchange data. For optimal
performance, place the Z600 within a metre and at
an angle of 30 degrees to the infrared port on the
PC/PDA, or other phone. An advantage of the nec-
essary proximity of devices is reduced risk of trans-
mitting data to other nearby devices. An infrared
link is a serial connection, which means that data
bits are sent one after another in a long stream. The
IrDA–SIR Data Link Standard is a protocol that
makes transmission of data faultless. The standard
provides a high level of noise immunity, which
means that the connection is not affected by fluo-
rescent light, sunlight and electromagnetic fields –
making it suitable for the modern office environ-
ment.
