1. Introduction

1. 1 Purpose

1. INTRODUCTION

This manual provides the information necessary to repair, calibration, description and download the features
of this model.

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. The manufacturer 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. The manufacturer 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 phones or compatibility with the net work,

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 Limitation

Maintenance limitations on the phones must be performed only by the manufacturer 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. Introduction

E. Notice of Radiated Emission

This model 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

A phone 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. information is ESD handling: Following

• 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.
