GENERAL
RITRON's SST-442 handheld is a small,
programmable two-way radio, designed to operate in
the 450-470 MHz professional FM communications
band. This handheld features push-button operating
controls, with the Push-To-Talk and Channel buttons
on one side of the radio. The On / Volume Up and
Volume Down / Off, volume and monitor controls are
on top.
Each radio can be “dealer” programmed to contain a
unique set of operating frequencies and options.
Selective signaling options include Quiet Call
(CTCSS) and Digital Quiet Call (DCS). Transmitter
power, operating bandwidth and battery saver are
among the options programmable on a per channel
basis.
Model Identification
The SST-442 model, serial number and FCC
Identification are displayed on a label located on the
back of the radio beneath the belt clip.
FCC REGULATIONS
Licensing
The FCC requires the radio owner to obtain a station
license for his radios before using them to transmit,
but does not require an operating license or permit.
The station licensee is responsible for ensuring that
transmitter power; frequency and deviation are within
the limits specified by the station license. The station
licensee is also responsible for proper operation and
maintenance of the radio equipment. This includes
checking the transmitter frequency and deviation
periodically, using appropriate methods.
Safety Standards
In 1991 the Institute of Electrical and Electronics
Engineers (IEEE), and in 1992 the American National
Standards Institute (ANSI) updated the 1982 ANSI
standard for safety levels with respect to human
exposure to RF energy. Over 120 scientists,
engineers, and physicians from universities,
government health agencies, and industry, after
reviewing the available body of research, developed
this updated Standard. In March 1993 the Federal
Communications Commission (FCC) proposed the
adoption of this updated Standard.
The SST-442 handheld radio is designed to comply
with this Standard. To limit your exposure to levels
at, or below, the levels in the Standard, please
observe the following:
•
Use only the antenna(s) available from RITRON
for this model. DO NOT attempt to substitute any
other antenna.
•
Keep talk times as short and infrequent as
possible. DO NOT depress the PTT button when
not actually wishing to transmit. The radio is
equipped with an internal timer to limit continuous
transmit times.
•
When transmitting, hold the radio in front of the
mouth at a distance of at least 4 inches. DO NOT
hold the radio in such a manner that the antenna
is next to, or touching, exposed parts of the body,
especially the face or eyes while transmitting.
•
In belt mounted applications, when transmitting,
remove the radio from the belt and hold away from
the body at least 4 inches.
•
When using external headset accessories, hold
the unit away from the body at least 4 inches while
transmitting.
•
DO NOT allow children to operate the radio.
