Blasting Caps And Blasting Areas; Mobile Radio Operation And Eme Exposure - Motorola pro7100 User Manual

Blasting Caps and Blasting Areas

To avoid possible interference with blasting
operations, turn off your radio when you are
near electrical blasting caps, in a blasting area,
or in areas posted: "Turn off two-way radio."
Obey all signs and instructions.
Note: The areas with potentially explosive
atmospheres referred to above include
fueling areas such as: below decks on
boats; fuel or chemical transfer or
storage facilities; areas where the air
contains chemicals or particles, such
as grain dust, or metal powders; and
any other area where you would
normally be advised to turn off a
vehicle engine. Areas with potentially
explosive atmospheres are often but
not always posted.

Mobile Radio Operation and EME Exposure

To assure optimal radio performance and that
human exposure to radio frequency
electromagnetic energy is within the guidelines
referenced earlier in this document, transmit
only when people inside and outside the
vehicle are at least the minimum distance away
from a properly installed, externally mounted
antenna.
Table 1 lists the minimum distance for several
different ranges of radiated power.
