This manual provides the information necessary to repair, calibration, description and download the features
of this model.
1. 1 Purpose
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.
1. 2 Regulatory Information
A. Security
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.

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.
ATTENTION
H. Electrostatic Sensitive Devices
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.
A phone may interfere with sensitive laboratory equipment, medical equipment, etc. Interference from
unsuppressed engines or electric motors may cause problems.
G. Interference and Attenuation
F. Pictures
The pictures in this manual are for illustrative purposes only; your actual hardware may look slightly
different.
