Introduction
Congratulations on your purchase of a Motorola two-
way radio. Your radio is a product of Motorola’s more
than 50 years of experience as a world leader in the
designing and manufacturing of communications
equipment. This radio offers superior quality, superior
performance, ultimate flexibility and years of reliable
and effective communications.
This radio incorporates the latest technology available
in two-way radio communications. The use of micro-
computer technology makes changing radio character-
istics such as operating frequencies and squelch
codes both economical and fast. Any computer
equipped dealer can easily reprogram your radio’s
operating characteristics.
The radio meets tough environmental demands while
providing cost-effective and reliable communications.
It meets established standards for low pressure, high
temperature, low temperature, temperature shock,
solar radiation, rain, humidity, salt fog, dust, vibration,
and shock. This radio also meets the Electronic Indus-
try Association RS316B electrical and mechanical
specifications. The Motorola Accelerated Life Test
(ALT) assures that possible failures brought on by field
stress and abuse are identified and designed out of
your radio before it reaches your hands.
All of these features provide for better, yet more cost
effective communications for you.
Coverage of this User Guide
This user guide describes the operation of radios with
and without a keypad.
