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. The C257/C261 is a dual-band phone that allows for roaming within the EGSM900 / DCS1800 or GSM850 / PCS 1900. C257/C261 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 17-key keypad, transceiver printed circuit board (PCB), microphone, charger and headphone connectors, and power button are contained within the candy bar formfactor 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 time1. The phone accepts 3V mini subscriber identity module (SIM) cards that fit into the SIM holder next to the battery. These telephones feature a 128 x 160 pixel high-resolution color graphics display and an internal antenna. Features C257/C261 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: • • • • • • • • • • A 128 x 160 pixel high-resolution color graphics display Internal antenna Caller line identification (CLI) (Network, subscription and SIM card or service provider dependent feature. Not available in all areas.) 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 Simplified text entry using iTAP™ predictive text entry July 1, 2005 9 Product Overview C257/C261 • • • • • • • 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. Simplified Text Entry The C257/C261 features 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. 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. Other Features Detailed descriptions of the other features can be found in the appropriate C257/C261 telephone user guides listed in the Related Publications section at the end of this manual. 10 July 1, 2005 Level 1-2 Service Manual General Functions General Functions Controls, Indicators, and Input/Output (I/O) Connectors The C257/C261 phone's controls are located on the front side of the device and on the keyboard as shown in below.

Figure 3. Telephone Menu Structure July 1, 2005 13 Tools and Test Equipment C257/C261 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). Note: 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. Operation For detailed operating instructions, refer to the appropriate User Guide listed in the Related Publications section toward the end of this manual.

Phone will not turn on or stay on. Probable Cause Verification and Remedy a) Battery either discharged or defective. Measure battery voltage across a 50 ohm (>1 Watt) load. If the battery voltage is <3.25 Vdc, recharge the battery using the appropriate battery charger. If the battery will not recharge, replace the battery. If battery is not at fault, proceed to b. b) Battery terminals open or misaligned. Visually inspect the battery terminals on both the battery and the phone. Realign and, if necessary, either replace battery or refer to a Level 3 Service Center for the battery connector replacement. If battery terminals are not at fault, proceed to c. c) Keypad defective. Replace the keypad. Temporarily connect a +3.6 Vdc supply to the battery terminals. Press and hold the PWR button. If phone turns on and stays on, disconnect the dc power source and reassemble with the new keypad. 2. Phone exhibits poor reception or erratic operation such as calls frequently dropping or weak or distorted audio. Connections to or from lower PCB defective. Check connection between the antenna and the lower PCB. 3. Display is erratic, or provides partial or no display. LCM defective. Replace the LCM. Verify that the fault has been cleared and reassemble the phone with the new LCM. 4. Incoming call alert transducer audio distorted or volume is too low. Speaker defective. Replace the speaker as described in the procedures. Verify that the fault has been cleared and reassemble the phone with the new speaker. 5. Phone transmit audio is weak. (usually indicated by called parties complaining of difficulty in hearing voice). Microphone defective. Replace the microphone as described in the procedures. Verify that the fault has been cleared and reassemble the phone with the new microphone. 6. Receive audio from earpiece speaker is weak or distorted. a) Connections to or from lower PCB defective. Check connection between the antenna and the lower PCB. If the connection is OK, proceed to b. b) Earpiece Speaker defective.
