(4) At this point the C-5000 must have its configuration programmed. Using either the
Wulfsberg RP software or the front panel knobs and buttons, program the required
system configuration data.
(5) The final programming step is to program the desired preset channels into the C-5000
using either the Wulfsberg RP software or using the front panel knobs and buttons. Start
with a limited set that will test the basic operations of the system such as:
Analog FM Modulation at a frequency in each band: 30-50, 138-174, 225-400,400-512,
806-870.
AM Modulation at a frequency in each band: 118-137, 225-400.
Encryption if available in the transceiver.
(a)
On the C-5000, tune transceiver system #1 to the manual channel. Using the
"EDIT" page on the C-5000 tune the manual channel for 30 MHz Rx and Tx
frequency, set Tx Power to Hi, and the Bandwidth to "S", no subaudible tone.
Press the "CLR" button to return to the "HOME" display page.
(b)
Press the "Test" Button and verify the squelch indicator lights up and noise audio
is heard in the headsets. Adjust RT #1 volume control (the small inner knob on
the left side) so that the noise can be heard.
(c)
If a single channel guard receiver or synthesized guard receiver is present
(-0201, -0301, -0401, -0501), select the guard receiver and press the "TEST"
button. Verify the squelch indicator lights and audio is heard.
(d)
If a second transceiver is in the system, select the manual channel for RT #2 and
input the same settings that were done to RT #1. Press the "Test" button to open
squelch and verify the squelch indicator for transceiver #2 lights and audio is
heard. If an audio panel is being used, make sure selector switches are in the
correct position to hear both Primary (RT #1) and Secondary headset audio (RT
#2).
(e)
Repeat (d) with transceiver #3.

Transmitter Tests
A. General
During transmitter verification tests, monitor any other radios or sensors that are present to
determine if interference between them and the C-5000 system exists.
(1) Input a 1 kHz sinewave tone into the primary microphone port and adjust input level for
.25 VRMS. DO NOT RELY ON THE TEST EQUIPMENT SETTING - MEASURE USING
AN AC VOLTMETER AT THE MICROPHONE JACK.
(2) Set the communication analyzer to FM mode. Tune the manual channel on the C-5000 to
the frequencies listed in Tables 1.0 through 1.5 (select appropriate transceiver model)
and record transmit power and modulation levels at the output of the radio. This will
verify the C-5000 is communicating with the transceiver and that microphone audio is
getting to the transceiver at the proper level. Verify that the C-5000 indicates a transmit
condition by showing the transmit indicator when the PTT is initiated. If modulation is not
