1. INTRODUCTION
1.1 Purpose
This manual provides the information necessary to repair, calibration, description and download the
features of the G7000/W7000.
1.2 Regulatory Information
A. 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 for your
telecommunications 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.
B. 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.
C. 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 G7000/W7000 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.
D. Maintenance Limitations
Maintenance limitations on the G7000/W7000 must be performed only by the LGE or its authorized
agent. The user may not make any changes and/or repairs expect as specifically noted in this
manual. Theref ore, note that unauthorized alternations or repair may affect the regulatory status of
the system and may void any remaining warranty.
E. Notice of Radiated Emissions
The G7000/W7000 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.

F. Pictures
The pictures in this manual are for illustrative purposes only; your actual hardware may look slightly
different.
G. Interference and Attenuation
An G7000/W7000 may interfere with sensitive laboratory equipment, medical equipment, etc.
Interference from unsuppressed engines or electric motors may cause problems.
H. Electrostatic Sensitive Devices
ATTENTION
Boards, which contain 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 like EEPROM to the factory, use the protective
package as described.
