Level 1-2 Service Manual Product Overview

Product Overview

The Motorola C113 features a global system for mobile communications wireless interface. It
also features a simplified icon and graphical user interface (UI) for easier operation in addition
to short message service text messaging (SMS), speed dialing, quick dialing, an alarm, a
calculator, games, and an address book.

C113 telephones support SMS in addition to traditional circuit switched transport technologies. Data transmission rates for GSM networks can potentially increase from the current rate of 9.6 kbps up to a theoretical maximum of 171.2 kbps.

The display and speaker, as well as the 21-key keypad, transceiver printed circuit board (PCB),
microphone, charger and headphone connectors, and power button are contained within the
candy bar form-factor housing. The user-replaceable 920 mAh Lithium-Ion (Li-Ion) battery
provides up to 180 minutes of talk time with up to 250 hours of standby time. The phone
accepts 1.8v and 3V mini subscriber identity module (SIM) cards that fit into the SIM holder
next to the battery. These telephones feature a black and white mode FSTN LCD Graphic 96 X
65 Dot-matrix , display and an internal antenna.

Features

C113 telephones use advanced, self-contained, sealed, custom integrated circuits to perform
the complex functions required for GSM GPRS communication. Aside from the space and
weight advantage, microcircuits enhance basic reliability, simplify maintenance, and provide a
wide variety of operational functions.

Features available in this family of telephones include:

• Telephones feature a black and white mode FSTN LCD Graphic 96 X 65 Dot-matrix
display

• Internal antenna

• Lower voltage technology that provides increased standby and talk times

• Extended GSM (EGSM) channels

• Tri-coder/decoder (CODEC) that allows full rate, half rate, and enhanced full rate modes of
transmission

• Display animation

• VibraCall® vibrating alert

• 5-Way navigation key

• SIM Toolkit™ Class 2 (STK) (Network, subscription and SIM card or service provider
dependent feature. Not available in all areas.)

• Backlight

• Speed-, Quick- and One-Touch dialing

• Call Forwarding and Holding

• Customized Menus

• Personal management tools calculator with currency converter, real time clock with date,
reminders, and caller profiling

• Other features

Caller Line Identification

Upon receipt of a call, the calling party's phone number is compared to the phone book. If the
number matches a phone book entry, that name will be displayed. If there is no phone book
entry, the incoming phone number will be displayed. In the event that no caller identification
information is available, an incoming call message is displayed.

Product Overview C113

SIM Toolkit™ - Class 2

SIM Application Toolkit is a value-added service delivery mechanism that allows GSM
operators to customize the services they offer their customers, from the occasional user who
requests sports news and traffic alerts, to a high call time business user who receives stock
alerts and checks flight times. Operators can now create their own value-added services menu
quickly and easily in the phone.

The customized menu will appear as the first menu and may be updated over-the-air with new services when customers request them.

Battery Function

The telephone displays a battery charge indicator icon in the idle screen to indicate the battery charge level. The gauge shows four levels: 100%, 66%, 33%, and Low Battery.

Removing the battery causes the phone to shut down immediately and loose any pending work (partially entered phone book entries or outgoing messages, for example).

All batteries can cause property damage and/or bodily injury such as burns if a conductive
material such as jewelry, keys, or beaded chains touches exposed terminals. The conductive
material may complete an electrical circuit (short circuit) and become quite hot. Exercise care
in handling any charged battery, particularly when placing it inside a pocket, purse, or other
container with metal objects.

If the battery is removed while receiving a message, the message is lost.

To ensure proper memory retention, turn the phone OFF before removing the battery.
Immediately replace the old battery with a fresh battery.

Level 1-2 Service Manual Subscriber Identity Module (SIM) and Identification Label

Subscriber Identity Module (SIM) and Identification Label

SIM

A SIM is required to access the existing local GSM network, or remote networks when traveling (if a roaming agreement has been made with the provider).

The SIM 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

Identification

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

Mechanical Serial Number (MSN)

• The MSN is an individual unit identity number and remains with the unit throughout its

life.

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

• The MSN is divided into 4 sections as shown in Figure 13.
