Any person authorized by a station licensee may are limited, point-to-point communication between
operate a base station or mobile unit without an
operator’s permit or license from the Federal Com­
munications Commission, unless the radio system
transmits on a frequency below 25 Mc/s. Some li­
censees issue authorization cards to their radio oper­
ators, a worthwhile control measure although not
required by FCC rules (see pages u and 12).
Permissible Communications
You are licensed to transmit only those messages
that are considered essential to the efficient conduct
of that phase of your business for which the license
was granted. Your radio may also be used for trans­
mission of any messages pertaining to the safety of
life or the protection of property. Personal messages,
except emergencies, are not authorized.
Emergency messages take priority over all others.
In transmitting emergency messages, the originat­
ing station may use the word “emergency” or one
of the international distress signals: “PAN” or
“MAYDAY” (see Page 8 ). All other stations ex­
cept the one being called should cease transmitting
and stand by until the emergency messages have
been handled.
Your system is licensed on one of the mobile radio
channels, set aside for communication between ve­
hicles, and between vehicles and their associated
base stations. Because the mobile radio channels
offices is not allowed where other communications,
such as wire lines, are available except in an emer­
gency when a message is essential to the protection
of life or property or when the message is of im­
mediate importance to mobile units reached only
by relay through another base station.
Remember that other people can hear you over
the radio. Since you are operating on a frequency
available to other licensees on a shared basis, you
may be heard not only by fellow employees, but by
outside people as well. You must, therefore, be sure
to comply fully with the FCC Rules and Regula­
tions. Three specific points to remember are: No
personal messages (except emergency). Absolutely
NO PROFANE LANGUAGE. Always give your
station call sign at the end of each contact (ex­
change of transmissions) or every 15 minutes. Iden­
tify yourself clearly and precisely. Your fleet units
know who you are, but someone else may also need
to know.
The fleet mobile radio station’s identification is
usually the same as the vehicle number for the con­
venience of the dispatcher at the base station. A
person, regularly using a particular vehicle may be­
come associated with that vehicle’s number. If,
however, he is assigned to another vehicle he cannot
use his original number. Both call and acknowledge­
ment must use the new vehicle number to insure
proper identification.
