I DTX-165-RR-SIG MODULES
1 INTRODUCTION
1.1 GENERAL
The RITRON DTX-165-RR-SIG module is a programmable 2-way radios, which operates in the
VHF professional FM communications band. Each of eight channels can be programmed to
contain a unique set of operating frequencies. The DTX-165-RR-SIG module is made up of two
PC boards, an RF board and a control/loader board. These two boards are enclosed in a metal
case with two connectors on one end; a 50 ohm BNC connector for connection to an antenna and
a DB-15 sub-miniature connector for control input/output and a power input connector on the
other end.
1.2 MODEL IDENTIFICATION
The part number system for the DTX-165-RR-SIG module is:
The module has a part number in the form of “DTX-A65-RR-SIG” where:
A is the major frequency band designator:
1=VHF (136-174 MHz bands)
2=216-222 MHz band
3=340-400 MHz bands
4=UHF (400-430 MHz and 450-470 MHz bands)
1.3 FCC REGULATIONS
1.3.1 LICENSING
For those frequency bands governed by FCC rules, the FCC requires that the radio owner obtain
a station license for his radio before using the equipment to transmit, but does not require an
operating license or permit. The station licensee is responsible for proper operation and
maintenance of his radio equipment, and for ensuring that transmitter power, frequency and
deviation are within the limits specified by the station license. This includes checking the
transmitter frequency and deviation periodically using appropriate methods. Note also, that
wideband operation (25/30 kHz channel bandwidth) may not be permitted.
1.3.2 PRODUCT CERTIFICATION
The DTX-165-RR-SIG module is certified by the FCC for operation in the United States and by
Industry Canada for operation in Canada on certain frequency bands and sub-bands for
transmission of either voice or data signals when aligned according to the alignment procedure
for the proper bandwidth and when operated as a complete unit in the metal case. Operation of
the RF board as a stand-alone unit or in combination with any other equipment, in any mode
outside the alignment procedure, or with the clipper filter electronically disabled will require the
filing of a new type acceptance application with the FCC by the user.
1.3.3 SAFETY STANDARDS-RF EXPOSURE (DTX-165)
RF ENERGY EXPOSURE AWARENESS AND CONTROL INFORMATION, AND
OPERATIONAL INSTRUCTIONS FOR FCC OCCUPATIONAL USE REQUIREMENTS:
BEFORE USING THIS 2-WAY RADIO, READ THIS IMPORTANT RF ENERGY AWARENESS
AND CONTROL INFORMATION AND OPERATIONAL INSTRUCTIONS TO ENSURE
COMPLIANCE WITH THE FCC’S AND IC’S RF EXPOSURE GUIDELINES.
NOTICE: This radio is intended for use in general population/uncontrolled conditions.
This 2-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide
communications between two or more users over a distance. It uses radio frequency (RF) energy
or radio waves to send and receive calls. RF energy is one form of electromagnetic energy. Other
forms include, but are not limited to, electric power, sunlight and x-rays.
