Level III Service Manual Product Overview

Product Overview

Motorola PF B95 and C21 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. PF B95 and
C21 incorporate a simplified icon and list-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
PF B95 is a dual band phone that allows roaming within the GSM 900 MHz and
digital cellular system (DCS) 1800 MHz bands. The PF C21 is a single band phone
operating in the personal communications services (PCS) 1900 MHz band.

PF B95 and C21 telephones support GPRS and SMS in additi on to traditional circuit
switched transport technologies. GPRS, where available, provides substantial
increases in mobile data communications performance and the efficie nt use of radio
spectrum. Data transmission rates for GSM networks can potentially increase fro m
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 ben efit 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 pla stic. The display and speaker, as well
as the 16-key keypad, transceiver printed circuit board (PCB), microphone, charger
and headphone connectors, and power button are con tained within the J form-factor
housing. The user-replaceable 600 mAh nickel metal hydride (NiMH) battery
provides up to 300 minutes of talk time with up to 180 hours of standby time
phone accepts 3V mini subscriber identity module (SIM) cards which fit into the
SIM holder underneath the battery. These telephones feature a 96 x 64 pixel 800
square millimeter high-resolution graphics display and an internal antenna.

. The

Features

PF B95 and C21 telephones use advanced, self-contained, seal ed, custom integrated
circuits to perform the complex funct ions 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 (PF B95 only)

• 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

• Supports GPRS, circuit switched, and SMS networks

• WAP 1.1 compliant

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.

Speaker Dependant Voice Activation

The voice dialing fea ture a l lows the use r to reca ll p re-p rogra mmed v oice 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) 1.1 Compliancy

In the WAP environment, access to the Internet is initiated in wireless markup
language (WML), which is derived from hypertext marku p 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 B95 and C21’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.

Level III Service Manual Product Overview

Simplified Text Entry

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.

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 pho ne number will be displ ayed. 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 Toolkit™ - Class 2

SIM Application Toolkit is a value-added service delivery mechanism that allows
GSM operators to customiz e 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 re ceives stock a lerts 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 p rovides a constant WAP co nnection through GPRS t o
carrier, service center, or factory flexed WAP site. The specific site can also be
entered by the user. Chat messaging is a carrier option.

Other Features

Detailed descriptio ns of these and the other features can be found in t he appropriate
PF B95 and C21 telephone user guides listed in the Related Publications section
toward the end of this manual.

Battery Fu nction

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.

Battery Removal

Removing the battery causes the device t o 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.

E

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 fresh battery.

For detailed operating instructions, refer to the appropriate User Guide listed in
the Related Publications section toward the end of this manual.

Subscriber Identity Module (SIM) and Identification

SIM

A SIM 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 net-

work.

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 Ce nter Database.
The MSN is divided into 4 sections as shown in Figure 16.
