Caution - Before operating this device, be sure to place the
antenna in the vertical position. This offers the best performance of your modem, and, at the same time, reduces
the risk of possible exposure to electromagnetic radiation
emanating from the antenna.
The antenna must be maintained at least 4 inches (or 10
cm) from users and nearby persons to comply with FCC
radiofrequency exposure limits (and to reduce the risk of
RF radiation) when the DATA 2000 is in operation."

1-1 What is the Uniden Data 2000?
The Uniden Data 2000 is a wireless CDPD PC Card which enables most
vendors’ laptops, handheld computers, and Personal Digital Assistants
with Type II PC Card slots to communicate with host-based applications
such as web servers, intranet servers, databases, dispatch systems, and
other host computer systems. The Uniden Data 2000 uses the Internet
suite of protocols running over the CDPD (Cellular Digital Packet Data)
system. The product is fully Windows compatible, supporting Windows
95, Windows NT, and Windows CE, and provides a Graphical User
Interface (GUI) which offers the user simplified access to operational
status and statistics, as well as the ability to configure, control, and monitor the performance of the device. The Uniden Data 2000’s compact size
makes it an easily portable communications tool that can be stored conveniently in a briefcase or purse when not in use.

1-2 What is CDPD?
CDPD or Cellular Digital Packet Data is a wireless, public access, packet data standard designed to operate over existing analog cellular
phone systems. Since it is designed to use existing cellular phone systems, CDPD provides a large coverage area, low service pricing, and
fast transaction execution. CDPD’s primary benefit is quick, inexpensive, and efficient transmission of data packets over the existing cellular network. Additional benefits include built-in encryption for security
(where applicable); a billing structure which charges for message size
rather than on-line time (depending on individual service provider’s
service plans); forward error correction methods that reduce the effects
of noise and interference on the airlink; and availability.
1.3 What is the PCMCIA Standard for PC Cards?
Over the past several years, mobile computers have experienced
explosive growth. While prices have fallen sharply, features are becoming more advanced and reliability has been greatly improved. One of
the most notable features of today’s mobile computers is the PC Card
slot. Over the last four years, the personal computer industry has rapidly adopted the PC Card slot feature, and today nearly 75 percent of laptops include a PC Card slot. This has been the driving force in the
innovation and development of PC Card technology.
In 1989, an international standards body and trade association was
founded, called the PCMCIA (Personal Computer Memory Card
International Association.). This organization was founded in order to
establish standards for Integrated Circuit cards and to promote interchangeability among mobile computers where ruggedness, low power,
and small size are critical.
Even though PCMCIA is a rather young technology, it has been quickly
adopted by every major personal computer manufacturer in the world.
Since it’s inception, PCMCIA has published a PC Card Standard which
contains all of the physical, electrical and software specifications for
PC Card technology. This standard is in a constant state of improvement by the PCMCIA technical committee.
