Product Overview

Product Overview
Motorola C350 mobile telephones feature global system for mobile communications (GSM) air interface, general packet radio service (GPRS) transport technology, and wireless application protocol (WAP) Internet browser. The mobile telephone uses a simplified icon and graphical-based user interface (UI) for easier operation, allow short message service (SMS) text messaging, and include clock, alarm, datebook, calculator, and caller profiling personal management tools. The C350 is a dual band phone that allows roaming within the GSM 850,GSM 900 MHz and digital cellular system (DCS) 1800 MHz and 1900 PCS bands. C350 telephones support GPRS and SMS in addition to traditional circuit switched transport technologies. GPRS, where available, provides substantial increases in mobile data communications performance and the efficient use of radio spectrum. 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. An increased data rate is by no means the only benefit provided by GPRS. A key advantage is the provision of a permanent virtual connection to the network. This "always on" connection is possible because GPRS uses packet data transfer so that, for example, email can be downloaded in "background mode." There is no need for the user to reconnect before requesting a service, eliminating connection set-up delays and adding convenience and immediacy to data services access. The "virtual" nature of this connection means that network resources are not consumed during periods when a user is not actually sending or receiving data. The telephones are made of polycarbonate plastic with a metal enclosure. The display and speaker, as well as the 18-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 600 mAh Lithium Ion (Li Ion) battery provides more than 300 minutes of talk time with up to 300 hours of standby time1. The phone accepts 3V mini subscriber identity module (SIM) cards which fit into the SIM holder under the rear housing cover. These telephones feature a 96 x 64 pixel 900 square millimeter high-resolution graphics display and an internal antenna.

Features
C350 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: · 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 messages2 · Supports GPRS, circuit switched, and SMS networks2 · WAP 1.2.1 compliant2 · Super enhanced sound engine

1. All talk and standby times are approximate and depend on network configuration, signal strength, and features selected. Standby times are quoted as a range from DRX=2 to DRX=9. Talk times are quoted as a range from DTX off to DTX on. 2. Network, subscription and SIM card or service provider dependent feature. Not available in all areas.

Product Overview

C350 Series

· 96 X 65 pixel color graphical display with 4 lines of text, 1 line of icons, and 1 line of prompts · Display zoom · Display animation · VibraCall® vibrating alert · 4-Way navigation key · Downloadable wallpaper and ring tones3 · Voice activation for phone book entries · Simplified text entry using iTAPTM predictive text entry · Calling line identification3 · Supports call diverting for incoming voice calls3 · Supports 3V SIM cards · SIM ToolkitTM Class 2 (STK)3 · Personal management tools calculator with currency converter, real time clock with date, reminders, and caller profiling · Phase II Unstructured Supplementary Service Data (USSD)3 · Hearing Aid Telephone Interconnection System (HATIS) support · Chat messaging via WAP over GPRS3 · Multiple destination SMS · TrueSyncTM Multi-Point Synchronization Capability

Speaker Dependant Voice Activation
The voice dialing feature allows the user to recall pre-programmed voice numbers simply by pressing the Voice/Ok key and speaking the desired voice tag. Up to 10 voice tags can be stored.



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) 1.2 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 C350'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.

3. Network, subscription and SIM card or service provider dependent feature. Not available in all areas.

Product Overview



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
iTAPTM 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 iTAPTM feature may not be available on the phone in all languages.

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.



User must subscribe to a caller line identification service through their service provider.

SIM ToolkitTM - 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.

Network Based Chat Messaging
The chat messaging feature provides a constant WAP connection through GPRS to carrier, service center, or factory flexed WAP site. The specific site can also be entered by the user. Chat messaging is a carrier option.

Personal Information Management
The C350 telephone contains a built in calendar with date book reminders and phonebook that can be synchronized easily to a computer or PDA.

Battery Information
Battery Charge Indicator
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.

Embedded Battery Removal
Removing the battery causes the device to immediately shut down and any pending work (partially entered phone book entries or outgoing messages, for example) is lost. 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.

E G


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 fresh battery.

G

Ensure battery switch is always in the ON position.
