Product Overview A760

Product Overview

Motorola A760 telephones are global system for mobile communications (GSM)
general packet radio service (GPRS) wireless application protocol (WAP)-enabled
mobile phones with full-featured personal information manager (PIM)
functionality. The A760 incorporates a large task-based touch screen user interface
(UI) featuring handwriting recognition for email and short message service (SMS)
text messaging. It is a tri-band phone that allows roaming within the GSM 900
MHz, and digital cellular system (DCS) 1800 MHz bands.

A760 telephones support GPRS, SMS, MMS in addition to traditional circuit
switched transport technologies.

A760 telephones have a clam form factor. They are made of a polycarbonate plastic
with the earpiece speaker located in the flip. The flip features a viewing window
that allows a portion of the display to be seen with the flip is closed. The bottom
part of the clam (front housing) contains the touch screen display, main printed
circuit board (PCB), microphone, external accessory connector, infrared (IR)
communications port, and headset jack. Also located in the front housing are the
voice, volume, power, page up, page down, and menu buttons, as well as the battery,
antenna, subscriber identity module (SIM) holder, and status light. A stylus, also
located in the front housing, is provided to aid manipulating the touch screen UI.

The A760 features a High definition display with a fine pitch 320 x 240 pixel high
color reflective TFT display to improve readability and useability.

The battery and battery door are integrated into a single unit to minimize overall
phone thickness. The phone accepts both 3V and 5V mini SIM cards which fit into
the SIM holder beneath the battery. The antenna is a fixed stub type antenna.

Level 1 and 2 Service Manual SIM Cards and Identification

SIM Cards and Identification

SIM Card

A SIM card is required to access the existing local GSM network and remote
networks when traveling.

The SIM card contains:

• All the data necessary to access GSM services.

• The ability to store user information such as phone numbers.

• All information required by the network provider to provide access to the
network.

Personality Transfer

A personality transfer is required when a phone is Express Exchanged or when the
main board is replaced. Personality transfers reproduce the customer's original
personalized details such as menu and stored memory such as phone books, or even
just program a unit with basic user information such as language selection.

Identification

Personality transfers performed at levels 1 and 2 service centers include only the

➧

information stored on the SIM.

Each Motorola GSM device is labeled with a variety of identifying numbers. The
following information describes the current identifying labels.

Mechanical Serial Number (MSN)

The Mechanical Serial Number (MSN) is an individual unit identity number and
remains with the unit throughout the life of the unit.

The MSN can be used to log and track a unit on Motorola's Service Center Database.

The MSN is divided into 4 sections as shown in Figure 19.

International Mobile Station Equipment Identity (IMEI)

The International Mobile station Equipment Identity (IMEI) number is an
individual number unique to the PCB and is stored within the unit's memory.

The IMEI uniquely identifies an individual mobile station and thereby provides a
means for controlling access to GSM networks based on mobile station types or
individual units. The full IMEI structure is listed in Table 3.
