Level 1 and 2 Service Manual Product Overview
Product Overview
Motorola K3 telephones represent the thinnest and slenderest 3G features in a
small and lightweight package. These Global System for Mobile communications
(GSM) General Packet Radio Service (GPRS) Wireless Application Protocol (WAP)
enabled mobile phones incorporate an icon based User Interface (UI) for easier
operation, allows Short Message Service (SMS) text messaging, Multi-media
Messaging Services (MMS), and includes Personal Information Manager (PIM)
functionality.
MOTOKRZR K3 ™ is a multi-band phone that allows roaming within the GSM 900
MHz, 1800 MHz Digital Cellular System (DCS), and PCS 1900 MHz bands, in
addition to the UMTS WCDMA 2100 MHz band.
K3 telephones have a clam form factor design. They feature an anodized aluminum
housing and have an externally viewable 96x80 1.0” 65K CSTN external display for
caller identification and date/time, an internal 176x220 1.9” 262K TFT display, and
the speaker located in the flip. The bottom part of the clam (front housing) contains
the keypad, transceiver printed circuit board (PCB), microphone, flex connection,
external accessory connector, smart button, volume buttons, and voice button. The
standard 750 mAh Lithium Ion (Li Ion) battery fits behind a removable back cover.
The phone accepts both 3V and 1.8V mini subscriber identity module (SIM) cards,
which fit into the SIM holder next to the battery. The antenna is internal.
Inexpensive direct connection to a computer or handheld device via USB or
Bluetooth™ for data and fax calls, and for synchronizing phonebook entries with
Mobile Phone Tools software, can be accomplished by using the optional data cable
and soft modem.
Features
K3 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:
• Ultra Slim form factor
• EDGE for high speed data access (class 12)
• Video Capture & Playback MPEG4 (15 fps CIF)
• Audio/Video streaming (3GPP)
• Video Progressive Download
• Dedicated Carrier Key
• Integrated Stereo Bluetooth Connectivity (Class 2)
• 2MP digital camera with 8x digital zoom
• MicroSD slot for upgradeable memory
• Push To Share (images, video, audio files)
• Dynamic Idle
• 22MB of embedded end user memory
• Rich, pre-loaded J2ME™ games, screen savers
• Downloadable themes, ringer tones, images, animations
• Image borders, text overlay, image editing
• Midi, MP3, AAC, AAC+ Enhanced, iTunes music player
• PIM functionality with Picture Caller ID
• Voice memo & enhanced predictive text

Product Overview MOTOKRZR K3
• Enhanced voice recognition
• Record up to 25 minutes of video on embedded memory
• Firmware Over-The Air (FOTA)
• UI Skinning
• Motosync – contacts (calendar, emails TBC)
Voice Commands and Voice Note Recording
Voice commands can be used for voice dialing phone numbers in the phone book
and for creating voice shortcuts for menu items.
K3 telephones also include a voice recorder that allows up to 2 minutes of personal
messages to be recorded. This feature has a complete set of record, playback, and
management tools that make it easy to store and maintain a list of personal memos.
Wireless Access Protocol (WAP) 2.0 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 K3 microbrowser can be configured for baud, idle timeout, line type, phone
number, and connection type.
SIM Application Toolkit
TM
- 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.
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 lan-
guages.
• 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.
➧
Bitmap image data will download as text. If the image is larger than the screen,
only part of the image will display.
➧
When the user receives a call while in browser mode, the browser will pause and
allow the user to resume after completing the call.

Level 1 and 2 Service Manual Product Overview
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 Incoming Call
message is displayed.
Other Features
Detailed descriptions of these and other K3 features can be found in the appropriate
user’s guide listed in the “Related Publications” section toward the end of this
manual.
➧
User must subscribe to a caller line identification service through their service
provider.

General Operation MOTOKRZR K3
General Operation
Controls, Indicators, and Input / Output (I/O) Connections
The K3 series telephone’s controls are located on the sides of the flip and on the
keypad. Indicators, in the form of icons, are displayed on the LCD (see Figure 2).
K3 phones have an audible alert transducer on the top and I/O connectors,
consisting of a charger/accessory port, located on the side of the phone. See Figure 1.
“Soft keys” refer to non-labeled keys that correspond to text options displayed on
the screen. The left and right soft keys perform the function shown in the corners
of the display. The right key will usually select an option whereas the left key will
usually exit a function or return to a previous screen.
The center select key opens the initial menu structure, or allows access to a

when handling, shipping, and servicing the internal components of this equipment.
G
Avoid stressing the plastic in any way to avoid damage to either the plastic or
internal components.
E
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 termi-
nals. 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.
