So what's new!!?? When a middle level official tries to tell the
truth to the public -- he gets "over-ruled" by the head office...!!
Everybody, you should keep a copy of the following message to take
to your next meeting where company "spokesmen" are present -- and
show it to your friends and neighbors in attendance (and the press!!)
so that they will know how much "pressure" is on those company
spokesmen to say only what their bosses want them to say.....!!!
(Same goes for a Moulder-like "expert witness" spokesman.)
........guru.........
P.S. Folks in Europe ought to carefully note -- and save -- this one.

Hi Roy:
If anyone still believes that industry is more concerned about our health
than profits, they might want to read this article from zdnet.

Cell phones -- unsafe at what speed?
By Jane Wakefield, ZDNet (UK)

Motorola says a New Scientist report on GPRS radiation safety was wrong, but
declines to explain why.
Mobile manufacturer Motorola is backtracking on recent comments by its
spokesman suggesting that GPRS, the high-speed successor to Global System
for Mobile Communications (GSM), might have to be made slower in order to
stay within radiation absorption guidelines.
Motorola Marketing Manager Rainer Lischetzki recently told New Scientist
that implementing GPRS at the speeds its marketing division has hyped --
between 27Kbps and 86Kbps -- could cause a phone to overheat. He also said
such speeds could push a phone's microwave radiation beyond European
guidelines on the energy that can be absorbed by the brain.
[.....WHICH European guidelines??.....guru.....The Salzburg Resolution??]
But Motorola (NYSE: MOT) now says the New Scientist report was at fault,
claiming that Lischetzki is not "qualified" to discuss GPRS issues despite
the fact that he is Motorola's technical marketing manager for GPRS.
ZDNet's request for an interview with Lischetzki was refused. According to
Mark Durrant, Motorola's director of communications, the company is not
prepared to risk "another inaccurate report."
Instead, Motorola has issued a statement conceding that, "Whilst the initial
GPRS phones that enter the market may not operate at their highest
theoretical data speeds, that fact is not related to the issues raised by
New Scientist." Motorola offers no explanation about why higher speeds will
not be available.
However, the Department of Trade and Industry (DTI) confirmed that higher
speeds could be potentially dangerous. "It is conceivable that GPRS devices
... could produce exposures above the levels specified in the Council
Recommendation," said a DTI spokesman.
Simon Mann, technical spokesman for the National Radiological Protection
Board (NRPB) agrees, saying that although mobile manufacturers will have to
observe regulations governing the emissions from mobile phones, it is
"entirely feasible" that some GPRS mobiles, particularly those at the top
end of the market, could tip over the (emission) limits."
The issue is speed
The issue revolves around whether or not GPRS mobile phones will operate at
the speeds mobile manufacturers are touting. Typically, GPRS mobiles are
hyped as transferring data about three to five times faster than current
mobiles, although consensus suggests these speeds are exaggerated.
Analog mobile phones have a transmitter that is on all the time when making
a call, with one phone having exclusive use of one radio channel. GSM phones
share channels, with up to eight phones taking turns to transmit short
bursts of data on a single channel. This means that although a GSM phone has
a maximum power output of two watts, in practice it transmits an eighth of
that -- quarter of a watt, maximum. This can, and frequently is, reduced
still further.
To save battery life and to increase the number of phones that can be
handled by the system, the mobile's power is automatically adjusted to the
minimum necessary to keep a reliable link with the base station.
GPRS uses exactly the same system, but to increase the amount of data
transferred a phone can use more than one slot. Thus a three-slot GPRS link,
carrying about 30 to 40Kbps, will use a maximum of three-quarters of a watt.
This is roughly the same as an analog phone used for a single voice call,
but as with GSM, the power levels will often be lower than the maximum,
especially in areas with many base stations or few buildings.
Average power levels are further reduced because GPRS is a packet-based
system: The transmitter is only on when data is being sent and is idle
otherwise. A file transfer from the phone to the base station will make the
transmitter work at full tilt; keystrokes or Web browsing will only fire up
the transmitter occasionally, reducing the average power output to a few
milliwatts.
