Product Overview Product Family 0C81
Product Overview
Motorola A388c telephones are global system for mobile communications (GSM)
general packet radio service (GPRS) wireless application protocol (WAP)-enabled
mobile phones with full-featured personal information manager (PIM)
functionality. The A388c incorporates a large task-based touch screen display user
interface (UI) featuring handwriting recognition for email and short message
service (SMS) text messaging. It is a tri-band phone that allows roaming within the
GSM 900 MHz, digital cellular system (DCS) 1800 MHz, and personal
communications services (PCS) 1900 MHz bands.
A388c 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 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. In addition to increased data
rate, GPRS provides 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” without need for the user
to reconnect before requesting a service. This eliminates connection setup delays
and adds convenience and immediacy to data services. The “virtual” nature of this
connection means network resources are not consumed during periods when a user
is not actually sending or receiving data.
Features
A388c telephones have a clam form factor. They are made of a polycarbonate plastic
with the earpiece speaker located in the flip. The flip features a viewing window
that allows a portion of the display to be seen with the flip is closed. The bottom
part of the clam (front housing) contains the touch screen display, main printed
circuit board (PCB), microphone, external accessory connector, infrared (IR)
communications port, and headset jack. Also located in the front housing are the
voice, volume, power, page up, page down, and menu buttons, as well as the battery,
antenna, subscriber identity module (SIM) holder, and status light. A stylus, also
located in the front housing, is provided to aid manipulating the touch screen UI.
The battery and battery door are integrated into a single unit to minimize overall
phone thickness. The phone accepts both 3V and 5V mini SIM cards which fit into
the SIM holder beneath the battery. The antenna is a fixed stub type antenna. The
service indicator (status light) displays flashing green while in-service, flashing
amber when roaming, flashing red while out of service, and alternating red / green
when ringing.
A388c 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
DRAFT
• Supports SMS, concatenated SMS, and cell broadcast messages
• Supports GPRS, circuit switched, and SMS networks
• Supports POP3, IMAP4, MIME and SMPT email protocols

Speaker Dependant Voice Recognition and Voice Note Recording
This feature allows voice tags to be used for voice dialing up to 25 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 (phone book menu structure or the shortcut editor).

DRAFT
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.
A388c telephones also include a voice note recorder that allows up to 3 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) 1.2.1 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 through the mobile
network.
The A388c’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.

When the user receives a call while in browser mode, the browser will pause and
allow the user to resume after completing the call.
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.
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 A388c features can be found
in the appropriate A388c telephone user’s guide listed in the “Related Publications”
section toward the end of this manual.
