Product Overview

Product Family C25 and C43

Product Overview

Motorola PF C25 and PF C43 mobile telephones feature global system for mobile communications (GSM) air interface, and wireless application protocol (WAP) Internet browser (PFC25 only). The PF C25 and PF C43 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. PF C25 telephones support SMS in addition to traditional circuit switched transport technologies.

PF C25 and PF C43 telephones are 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 flat form-factor housing. The phone accepts both 3V and 5V mini subscriber identity module (SIM) cards which fit into the SIM holder underneath the battery. The antenna is a fixed stub type antenna.

Features

		The PF C25 and PF C43 telephones use advanced, self-contained, sealed, custom
		integrated circuits to perform the complex functions required for GSM communica-
		tion. Aside from the space and weight advantage, microcircuits enhance basic
		reliability, simplify maintenance, and provide a wide variety of operational func-
		tions.
	PRELIMINARY	Features available in this family of telephones include:
		• Ergonomic design for comfort and enhancement of one hand operation
		• Icon Based Simplified User Interface
		•	Animated Screen Savers
		• 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
		• Supports SMS, concatenated SMS, and cell broadcast messages
		•	WAP 1.1 compliant
		• 700 mm2 98 x 64 pixel, high resolution 4 line graphic display
		• Icon based simplified user interface
		•	Display zoom
		•	Display animation
		• 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

Product Overview

Speaker Dependant Voice Recognition and Voice Note Recording

This feature allows voice tags to be used for voice dialing up to 20 phone numbers in the phone book 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 (i.e., via 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 provide the option to store voice tags onto the SIM card, voice tags are added to the phone’s memory.

Wireless Access Protocol (WAP) 1.1 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 via 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 will download as text. If the image is larger than the screen, only part of the image will display.

If the user receives a call while in browser mode, the browser will pause and allow 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

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, the message INCOMING CALL is displayed.

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 through to the phone.

Detailed operating instructions for these and the other PF C25 and PF C43 features can be found in the appropriate PF C25 and PF C43 telephone user’s guide listed in the “Related Publications” section toward the end of this manual.

Figure 3. PF C25 Alphanumeric keys

Liquid Crystal Display (LCD)

The LCD provides a high contrast backlit display for easy readability in all light conditions. The large bit-mapped 98 x 64 pixel display includes 3 lines of text, 1 line of icons, and 1 line of soft key labels.

Display animation makes the phone’s menus move smoothly as the user scrolls up and down. Turn animation off to conserve the battery.

Whether a phone displays all indicators depends on the programming and services to which the user subscribes.
