Product Overview Product Family C25
Product Overview
Motorola C300 mobile telephones feature global system for mobile communications
(GSM) air interface. The C300 also provides a wireless application protocol (WAP)
Internet browser. The C300 telephones incorporate a new user interface (UI) for
easier operation, allows short message service (SMS) text messaging, and includes
personal information manager (PIM) functionality. It is a dual-band phone that
allows roaming within the GSM 900 MHz and digital cellular system (DCS) 1800
MHz bands. PFC25 telephones support SMS in addition to traditional circuit
switched transport technologies.
The C300 is made of a polycarbonate plastic. The display and speaker, as well as
the keypad, transceiver printed circuit board (PCB), microphone, external accessory
connector, volume buttons, power button, and voice button, are contained within
the candy-bar form-factor housing. The phone accepts both 3V and 5V mini
subscriber identity module (SIM) cards which fit into the SIM holder under the
battery. The antenna is contained within the phone’s housing.
Features
The C300 telephones use advanced, self-contained, sealed, custom integrated
circuits to perform the complex functions required for GSM 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:
• Ergonomic design for comfort and enhancement of one-hand operation
•700 mm
• Icon based simplified user interface
• Animated screen savers
• Display animation
• Display zoom
• Low-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
• Supports SMS, concatenated SMS, and cell-broadcast messages
• EMS 5.0 messaging support
• WAP 1.2.1 compliant
• M-Services support
• VibraCall® vibrating alert
• Voice recorder personal memo feature
• Voice activation for phone book entries and menu shortcuts
• Simplified text entry using iTAP™ predictive text entry
• Supports calling name presentation
• Supports call forwarding for incoming voice, fax, and data calls
• Supports 3V and 5V SIM cards
• SIM Toolkit (STK), Class II

Level 1 and 2 Service Manual Product Overview
Speaker Dependant Voice Recognition and Voice Note Recording
This feature allows you to use voice tags for voice dialing up to 20 phone numbers
in the phonebook and for creating up to 5 voice shortcuts for menu items. The phone
must be “trained” by the voice tag being read into the phone’s memory twice before
it is recognized.
Voice tags can be added to the phone’s memory using the usual name addition
methods using the phone book menu structure or with the shortcut editor).
➧
➧
➧
➧
The user cannot place or receive calls while adding voice tags to the phone’s memory.
Because the GSM standard does not allow you to store voice tags on the SIM card,
voice tags are added to the phone’s memory.
Wireless Access Protocol (WAP) 1.2.1 Compliancy
In the WAP environment, access to the Internet is initiated in wireless markup
language (WML), which is derived from hypertext markup language (HTML). The
request is passed to a WAP gateway which retrieves the information from the server
in standard HTML (subsequently filtered to WML) or directly in WML if available.
The information is then passed to the mobile subscriber using the mobile network.
The PF C25’s microbrowser can be configured for baud, idle timeout, line type,
phone number, and connection type.
Bitmap image data downloads as text. If the image is larger than the screen, only
part of the image displays.
If the user receives a call while in browser mode, the browser pauses and allows
the user to resume after completing the call.
Simplified Text Entry
There are three different ways to enter text using the phone keypad:
• iTAP™ predictive text entry. Press a key to generate a character and a
dynamic dictionary uses this to build and display a set of word or name
options. The iTAP™ feature may not be available on the phone in all
languages.
• Tap. Press a key to generate a character.
• Numeric. The keypad produces numeric characters only. For some text areas
this is the only method available; for example, phone numbers.
Caller Line Identification
When the phone receives a call from a caller whose phone number is stored in the
phonebook, the caller’s name displays. If the caller does not have a phonebook entry,
6881041B25 October 14, 2002 7
Page 12
Product Overview Product Family C25
the phone number displays, if no caller identification information is available,
INCOMING CALL displays.
User must subscribe to a caller line identification service through their service
➧
provider.
Call Forwarding
Call forwarding is a network feature that diverts incoming calls to another phone
number if the user or phone is unavailable, or the user does not wish to receive calls.
This option can be used to:
• Divert all incoming voice calls unconditionally
• Divert incoming voice calls whenever the phone is unavailable, busy, not
reachable, or not answered
• Divert incoming fax calls
• Divert incoming data calls
• Allow all calls to the phone.
Detailed operating instructions for these features and other C300 features are found
in the appropriate C300 telephone user’s guides listed in the “Related Publications”
section toward the end of this manual.

➧
All batteries can cause property damage and/or bodily injury such as burns if a
conductive material such as jewelry, keys, or beaded chains touch 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 will be lost.
To ensure proper memory retention, turn the phone OFF before removing the
battery. Immediately replace the old battery with a fully charged battery.
For detailed operating instructions, refer to the appropriate User’s Guide listed in
the Related Publications section toward the end of this manual.

SIM Card
A SIM (Subscriber Identity Module) card 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 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.
Identification
Each Motorola GSM device is labelled 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.
