FCC RF Exposure Information
Warning!
Read this information before using this device.
In August 1996 the Federal Communications Commission (FCC) of the United States
with its action in Report and Order FCC 96-326 adopted an updated safety standard for human
exposure to radio frequency electromagnetic energy emitted by FCC regulated transmitters. Those
guidelines are consistent with the safety standard previously set by both U.S. and international
standards bodies. The design of this device complies with the FCC guidelines and these
international standards.

2. Overview
2.1 Application Descriptions
The CDMA Wireless Data Modem is a complex consumer communications instrument that relies
heavily on both digital signal and embedded processor technologies. The Wireless Data Modem
manufactured by AnyDATA.NET supports Code-Division-Multiple-Access(CDMA). This operates in
PCS spectrum.
In a continuing effort to simplify the design and to reduce the production cost of the Wireless Data
Modem, AnyDATA.NET has successfully developed the EMIII-DUAL. The EMIII-DUAL is
AnyDATA.NET’s latest compact Wireless Data Modem operating in PCS spectrum, also contains
complete digital modulation and demodulation system for CDMA standards as specified in IS-95 A/B and
IS-2000.
The subsystem within the EMIII-DUAL includes a CDMA processor (MSM5100), an integrated
CODEC with an ear piece and microphone amplifiers, and an RS-232 serial interface supporting forward
link data communications of a rate of 153.6kbps.
The EMIII-DUAL provides external interface. External interface includes the standard RS-232,
Digital Audio, and External On/Off control.
The EMIII-DUAL has the capability to power down unused circuits in order to dynamically
minimize power consumption.

4. Interface Descriptions
4.1 Overview
This chapter covers information required to design the EMIII-DUAL into a subscriber unit
application. In addition, the internal signals that are necessary for complete understanding of the UART
interfaces are described below.
4.2 RS232 Interface (Standard)
The Universal Asynchronous Receiver Transmitter (UART) communicates with serial data that
conforms the RS-232 Interface protocol. The modem provides 3.0V CMOS level outputs and 3.0V
CMOS switching input level. And all inputs have 5.0V tolerance but 3.0V or 3.3VCMOS logic
compatible signals are highly recommended.
All the control signals of the RS-232 signals are active low, but data signals of RXD, and TXD Are
active high. The UART has a 64byte transmit (TX) FIFO and a 64byte receive (RX) FIFO. The UART
Features hardware handshaking, programmable data sizes, programmable stop bits, and odd, even, no
parity. The UART operates at a 115.2kbps maximum bit rate.

7. FCC Notice
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the interference by one or more of the
following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
Consult the dealer or an experienced radio/TV technician for help.
