1. Introduction
1.1 Purpose
This manual provides the information necessary to repair, calibration, description and download the features of
the GM360.
1.2. Regulatory Information
1.2.1 Security
Toll fraud, the unauthorized use of telecommunications system by an unauthorized part (for example, persons
other than your company’s employees, agents, subcontractors, or person working on your company’s behalf) can
result in substantial additional charges you’re your telecommuni
cations services. System users are responsible for
the security of own system. There are may be risks of toll fraud associated with your telecommunications system.
System users are responsible for programming and configuring the equipment to prevent unauthorized use. LGE
does not warrant that this product is immune from the above case but will prevent unauthorized use of
common-carrier telecommunication service of facilities accessed through or connected to it. LGE will not be
responsible for any charges that result from such unauthorized use.
1.2.2 Incidence of Harm
If a telephone company determines that the equipment provided to customer is faulty and possibly causing
harm or interruption in service to the telephone network, it should disconnect telephone service until repair can
be done. A telephone company may temporarily disconnect service as long as repair is not done.
1.2.3 Changes in Service
A local telephone company may make changes in its communications facilities or procedure. If these changes
could reasonably be expected to affect the use of the GM360 or compatibility with the network, the telephone
company is required to give advanced written notice to the user, allowing the user to take appropriate steps to
maintain telephone service.
1.2.4 Maintenance Limitations
Maintenance limitations on the GM360 must be performed only at the LGE or its authorized agents. The user may
not make any changes and/or repairs expect as specifically noted in this manual. Therefore, note that
unauthorized alternations or repair may affect the regulatory status of the system and may void any remaining
warranty.

LG Electronics 7/147 LGE Property
1.2.5 Notice of Radiated Emissions
The GM360 complies with rules regarding radiation and radio frequency emission as defined by local regulatory
agencies. In accordance with these agencies, you may be required to provide information such as the following
to the end user.
1.2.6 Pictures
The pictures in this manual are for illustrative purposes only; your actual hardware may look slightly different.
1.2.7 Interference and Attenuation
An GM360 may interfere with sensitive laboratory equipment, medical equipment, etc. Interference from
unsuppressed engines or electric motors may cause problems.
1.2.8 Electrostatic Sensitive Devices
ATTENTION
Boards, which contains Electrostatic Sensitive Device(ESD), are indicated by the sign. Following information is
ESD handling: Service personnel should ground themselves by using a wrist strap when
exchange system boards.
When repairs are made to a system board, they should spread the floor with anti-static mat which is also
grounded. Use a suitable, grounded soldering iron. Keep sensitive parts in these protective packages until these
are used. When returning system boards or parts such as EEPROM to the factory, use the protective package as
described.

LG Electronics 19/147 LGE Property
3.2.1 General Description
S-GOLD3TM is a GSM/EDGE single chip mixed signal Baseband IC containing all analog and digital functionality of
a cellular radio. Additionally S-GOLD3TM Provides multimedia extensions such as camera, software MIDI, MP3
sound. It is designed as a single chip solution, integrating the digital and mixed signal portions of the base band
in 0.09um, 1.2V technology.
The chip will fully support the FR, EFR, HR and AMR-NB vocoding.
S-GOLD3TM support multi-slot operation modes HSCSD (up to class 10), GPRS for high speed data application (up
to class 12) and EGPRS (up to class 12) without additional external hardware.

z
Clock system
The clock system allows widely independent selection of frequencies for the essential parts of the S-GOLD3.
Thus power consumption and performance can be optimized for each application.
