1.1 Purpose

1. Introduction

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.

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. 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.

1 Q I can’t remember the PhoneLock password.

When the password and pin are locked, power o and press ‘Power key + Volume down key’ for Factory Reset.

A

- When the pattern is locked in Gmail setting, press the ‘Forgot’ button to set a new pattern.

- When no Gmail is set, press ‘Power key + Volume down key’ for Factory Reset.

How do I put in and take out les from the SD card?

To write/delete les on the SD card, connect the phone to PC via MTP.

First, download and install the USB driver. Connect the USB data communication cable, and do the following.

4 Q

A

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

GPS signals are so weak that location info may not be found due to weather conditions or other surrounding factors(indoors, radio wave reections).

When Setting->Location access -> Wi-Fi & mobile network location is ticked, location info may be brought from a nearby base station. This may not get a correct location info due to a wider margin of error than GPS.

Tick ‘GPS Satellites,’ stay outdoors and get the current location via GPS, which will reduce the margin of error.

5 Q

The downloaded application isn’t compatible?

Specic descriptions are needed about incompatibility issues.

Generally, incompatibility issues arise because they do not consider compatibility when designing apps in the rst place.

A

Inform us of the specic incompatible app. We’ll check it out.

Thanks.

How do I make an e-mail account?

Email protocols, e.g. EAS, IMAP4, POP3 are supported.

Register an account as below.

(If you have not registered any account, you’ll be automatically led to the registration screen on running the email app.)

* EAS account

Among email service providers, select MS Exchange >Enter email addr & pw (do not change the user name except when the email addr ID does not match the user name.) >Select the server addr, domain and SSL use > Set reception intervals and email synchronization period > (Set security type conforming to the server) > Done.

* IMAP4, POP3

Select an email service provider >Enter email addr and pw > (Make sure your account supports IMAP4 or POP3 service) > Select a reception server and security type(automatic input if a service provider has already been set) > Select the sending server and security connection(automatic input if a service provider has been already set)> (Generally, SMTP user name and pw are same as the email addr and pw provided initially) > Done.

8 Q

A

E-mail registration doesn’t work.

1. Email service uses data. Make sure WiFi or Data is available.

2. Check out email addr and pw.

3. Check out your email account service info(IMAP, POP3, SMTP).

4. Inquire the email service administrator about EAS-related server info.

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

That is because the service is running in the background of the app.

For example, phone or email apps need inform users of incoming calls or emails even though they are killed.
