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

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.
