1. INTRODUCTION

1.1 Purpose

This manual provides the information necessary to repair, calibration, description and download the

features of the KS360 Series.

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 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.

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 KS360 Series 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 KS360 Series 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.

1. INTRODUCTION

E. Notice of Radiated Emissions

The KS360 Series 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 KS360 Series 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 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.
