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 this phone 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 this model 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

2. INTRODUCTION

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

Phone may interfere with sensitive laboratory equipment, medical equipment, etc.Interference from unsuppressed engines or electric motors may cause problems.

H. Electrostatic Sensitive Devices

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.

ATTENTION

• 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.

1 Q I can’t remember the PhoneLock password.

In case of password, pin lock, proceed with factory reset through Volume Up key + Home key + Power key with the power being o.

- For pattern lock with Gmail setting, press the forgot button to set a new pattern

A

lock.

- If Gmail isn’t set, use Factory Reset by pressing the Volume Up key + Home key + Power key.

1. How to disable Pattern Lock, Password and PIN.

Request for development

2. Request to check out if it is specied in the user manual.

3. Description on HW Factory Reset Key combination and how to do it.

2 Q How do I put in and take out les from the SD card?

To write or delete les on the SD card, you need to connect the phone to your PC via a Media sync (MTP).

First, download and install the USB Driver. Then, check out the following with the USB communication cable being connected.

4 Q The GPS location isn’t right, what should I do?

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

If you check Setting->Location serivces -> GPS satellites and nd current location with GPS outdoor, you can reduce inaccuracy.

5 Q The downloaded application isn’t compatible?

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.

6 Q How do I make an e-mail account?

Email supports EAS, IMAP4, POP3 protocol. The registration order is as follows. (If no account is registered, the registration screen is automatically connected when

using the e-mail.)

* EAS account

Among e-mail service providers, choose MS Exchange > enter e-mail address, password (The user name isn’t changed unless the e-mail ID and user name is dierent.) >Choose server address, domain and SSL > Set receiving interval, e-mail activating term > (Security setting following the server setting) > Conrm

3. CIC AND SERVICE CENTER

A

* IMAP4, POP3

Select among e-mail service providers > enter e-mail address, password > (Check if your account supports IMAP4 or POP3 service) > Choose receiving server and security type(Automatic enter and progress if the service provider is already entered) > Select sending server and security connection(Automatic enter and progress if the service provider is already entered) > (Generally, SMTP user name and password is the same as the e-mail address and password entered in the rst place) > Conrm

7 Q E-mail registration doesn’t work.

1. Email service uses data. Check out Wi-Fi or data are available.

2. Check out the email address and password.

A

3. Check out if your email supports the service((IMAP, POP3, SMTP)).

4. For EAS, contact the service administrator to see the server info.

3. CIC AND SERVICE CENTER

8 Q

A

Unused application shows up as a using program even though it is all killed. What should I do?

It’s because the apps services are being run in the background. For example, phone or email app is supposed to let the user know any incoming calls

or messages even when they are killed.
