1. INTRODUCTION

1.1 Purpose

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 commoncarrier 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.

1. INTRODUCTION

D. Maintenance Limitations

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 Emissions

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. 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.

What should I do to add or remove les to and from the SD card?

To write or delete les on the SD card, you need to connect the phone to your PC via a MTP

1. Firstly connect device to PC using USB Cable, then a pop-up about USB

Connection Type will be displayed. Set connection with MTP.

2. Choose connection setting pop-up in PC as follows.

3. Then, explorer pops up and you can open SD card. You can move/copy le

4 Q

What should I do to deal with the wrong GPS location?

GPS signals are so weak that weather conditions or surrounding environment such as radio wave reection may keep locations from being captured.

*If Setting->Personal>Location services is checked on the Google’s location service, the location info can be brought from nearby bases. This, however, has wider margin of error than GPS that the location info captured may not be correct.

If you check Google’s location service and nd current location with GPS outdoor, you can reduce inaccuracy.

What should I do to deal with the incompatible apps downloaded?

You need to describe the incompatible status specically.

Incompatibility, in general, seems to result from not having considered the compatibility when they built the apps.

et us know the incompatible apps. We’ll nd out what the problems are.
