General Safely Information
Exposure to Radio Frequency Signals
You wireless handheld portable telephone is a low power radio transmitter and
receiver. When it is ON, it receives and also sends out radio frequency (RF) s i g
nals.
∙ International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1996
∙ Verband Deutscher Elektrotechniker(VDE) DIN-0848
∙ United States Federal Communications Commission, Radio Frequency Exposure
Guidelines(1996)
∙ National Radiological Protection Board of the United Kingdom, GS 11, 1988
∙ American National Standards Institute(ANSI) IEEE. C95. 1-1992
∙ National Council on Radiation Protection and Measurements(NCRP). Report 86
∙ Department of Health and Welfare Canada. Safety Code 6
These standards were based on extensive scientific review. For example, over
120 scientists, engineers, and physicians from universities, government health
agencies, and industry reviewed the available body of research to develop the
updated ANSI Standard.
The design of your phone complies with these standards when used normally.
Use only the supplied or an approved replacement antenna. Unauthorized
antennas, modifications, or attachment could damage the phone and may violate
local agency regulations.
Summary and Electrical Performance
Introduction
Congratulations on your purchase of a cellular telephone from Motorola, the world
leader in cellular technology.
All Motorola cellular telephones are manufactured to exacting specifications and
worldclass quality standards, and are designed to withstand the harshest
environmental conditions. Our commitment to Total Customer Satisfaction and
over sixty five years of experience in personal communications mean you can
depend upon the quality of this Motorola product.
Motorola Digital Cellular Phone V680 is a super-compact, super-light type of the
mobile communication terminal devices. It is a cellular communication device that
employs the Code Division Multiple Access (CDMA) technology with spectrum
efficiency, economy, price competitiveness and high portability.
As one of the modulation or multiple access methods, CDMA has adopted the
direct sequence spread spectrum communication method mainly used for the

military communication devices to maintain security and to ease the difficulty in
call connection in the densely populated area such as the present metropolitan
area. Its soft/softer handoff, hard handoff and dynamic RF power control
technologies help resolve the call disconnection. In addition, it provides a right
solution to address the subscriber capacity problems by enabling the subscribers
in certain areas to use of the same frequency.
The CDMA digital cellular network is configured with the Mobile Switching Office
(MSO), the Base Station Controller (BSC), Base Station Transceiver System
(BTS) and the Mobile Station (MS). And MS and BTS comply with the IS-95A OR
TSB-74 specifications.
The relevant MS specifications are as follows:
- IS-95A (Common Air Interface): Protocol regulations between MS and BTS
- TSB-74 ; Support for 14.4kbps data rate and PCS interation for wideband
spead spectrum cellular systems.
- IS-98: Least performance specifications for MS hardware
