Section 2
PRELIMINARY PERFORMANCE TEST

1. Apply power to the radio and DS-400. The DS-400 will display 27.155 unless the home channel option has been installed.

2. Check the first digit on the DS-400 for a full 2 display. If the first digit displays an L, refer to the troubleshooting section of this manual.

3. To insure the receiver is operating on 27.155, connect a signal generator to the antenna connector. Set the generator output frequency to 27.1550 MHz (Ch.16) and the output amplitude to 100uV. The radio should receive this signal when the 400 is set to 27.155.
This test indicates correct DS-400 installation and programming. In most cases the receiver will operate prior to any alignment. To attain maximum range and performance, refer to the alignment section.
