4.7 ARi-195e Adjustments
After programming the ARi-195e and connecting the radio interface harness to the radio transceiver, attach the terminal
to the interface harness. Observe normal static prevention practices.
• Apply power to the radio and turn the power switch on.
• Set the service monitor to receive on the transmitter frequency. If the service monitor does not incorporate an
oscilloscope, connect an external oscilloscope to the demodulation output.
• Using a service monitor generate a 1000 Hz signal deviated at 4.0 KHz and adjust R8 to obtain 100mvp-p at
TP1.
