1. INTRODUCTION

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 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 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.

1. INTRODUCTION

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.

Q

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

A

Your current location may not accurate depending on the location in use. (Open sky, indoor, semi indoor) - You may check Google location service under Open sky condition by following Setting > Location Services > GPS satellite, Google location service - It may be less accurate under indoor/semi indoor condition if phone fails to find satellite even after GPS satellite and Google location service.

Q

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

A

1. Uninstall

Q

What should I do to create an email account?

A

You should check if data is available when you initiate your account. (You need to check if data is available under Wi-Fi and Local state) If data is available, you can proceed after entering ID and Password.

Q&A

Q

Wi-Fi connection does not work properly.

A

There may be many reasons that Wi-Fi is not connected. Please, check followings. 1. Check if Wi-Fi is turned ON. 2. AP information and the information user enter can be different. 1) For your access, check security type and password of AP security information. 2) AP information can be renewed. “Forget” the former AP by clicking and try again to connect when AP list is newly updated. 3. Check if you are trying to connect AP which requires you authorization by mobile carriers. 1) If your device is not authorized by carrier, you may not be able to connect or use Wi-Fi. 4. In case of the problem on DHCP server, dynamic IP address may not be allocated. If so, please find AP manager.

1. Charging Procedure

3. Troubleshooting Setup

- Connect TA or u-USB Cable

- Connect TA and battery to the phone

- Control the charging current by LP8727-B IC - Charging current flows into the battery 2. Check Point

4. Troubleshooting Procedure

- Connection of TA or USB Cable

- Check the charger (TA or USB Cable)

- Charging IC (LP8727-B)

- Check the OVP Circuit

- Battery

- Check the Charging IC - Check the battery
