8.5.A General
It is absolutely essential that the technician read and understand the operation and
programming capabilities of the RT-7000 PMR/RMR as documented before attempting
to test the installation.
The RT-7000 PMR/RMR can control up to five radio systems composed of various
Cobham radios. It is the responsibility of the installer to understand the capabilities of
the individual radios and associated antenna systems. The RT-7000 PMR/RMR must
be programmed with configuration information BEFORE it will properly communicate
with any transceivers. This programming can be performed with a PC (Cobham
Installation Configuration Tool Software (P/N 320-171803-XX) and cable P/N 129-
271603-XX).
8.5.B Required Equipment
In order to perform the system checkout procedures the installer must have a means
by which to perform basic transmit (TX) and receive (RX) functions to/from the RT-
7000 PMR/RMR system. To fully verify the RT-7000 PMR/RMR system is functioning
properly the following equipment is required:
 A radio capable of AM/FM Modes of operation between 29.7 to 960 MHz e.g.
another C-5000 system with similar radio(s) connected; AM and FM handheld
radios, AM and FM base stations, etc.
 Aircraft headset with microphone
 Available aircraft power
 Antennas connected to proper radio RF ports
 RT-7000 PMR Operator’s Manual, P/N 150-071770
 Ensure all system connectors are securely connected
8.5.C Checkout Procedure
(1) Check the condition and mounting of the equipment including RT-7000 PMR/RMR
mating connectors and mounting hardware, and antenna condition, mounting
hardware, weather seal, and cable connections.
(2) Apply power to the system. If RT-7000 PMR/RMR does not turn on automatically,
push the "ON" button. The RT-7000 PMR display will show various initialization
screens and after 30 second will display the "HOME" page.
(4) Verify keyboard and backlit dimming functions work properly if the installation is
set up with backlight control. This is especially important for night vision ops.
8.5.D Transmitter Tests
Note: these test should only be performed in bands/frequencies authorized to the
operator.
(1) Set the RT-7000 PMR/RMR to an AM Lo Split frequency between 30.00 and
399.00 MHz; select transceiver 1, and put the RT-7000 PMR/RMR into transmit mode
(press PTT for transceiver 1). Talk into the aircraft microphone with a strong voice
(say and hold the word “two”). This will verify that microphone audio is getting to the
transceiver at the proper level. Verify that the RT-7000 PMR/RMR indicates a transmit
condition by showing the transmit indicator when the PTT is initiated.
