Using the stereo monitor, verify that pilot tone injection is between 8% and
10% modulation. If it is outside these parameters, adjust it to 9% via

If the measured pilot level varies by more than a few tenths of percent
from the pilot level indicated, this indicates there may be a problem
elsewhere — either in your measuring setup, or with the 8300.

Optional tests.
A)
You can test each GPI (Remote Interface) input for functionality in the obvi-
ous way, by programming a function for it and then verifying that the func-
tion executes when you activate the input. To program a GPI input, see
Remote Control Interface Programming
on page 2-36.
B)
You can test the RS-232 Port 1 for functionality by verifying that you can con-
nect to a PC through a null modem cable. See
Networking and Remote Con-
trol
starting on page 2-37 (in particular, step 4 on page 2-39).
10.
Return OPTIMOD-FM to service.
A)
Remove the 600
resistors connected across the outputs.
B)
Restore your normal operating parameters, using the notes you made in step
(1.B) on page 4-7.
