1.1. Purpose
This manual provides the information necessary to repair, calibration, description and download the
features of the F9200.
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 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.
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 F9200 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 F9200 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.
Therefore, note that unauthorized alternations or repair may affect the regulatory status of the system
and may void any remaining warranty.

1.2.5. Notice of Radiated Emissions
The F9200 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 F9200 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 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 such as EEPROM to the
factory, use the protective package as described.
