tion. Such users must fully understand the material in Section 3 of this manual to
achieve the best results from this exercise.
Compared to competitive processors, the 8700i offers a uniquely favorable set of
trade-offs between loudness, brightness, distortion, and build-up of program densi-
ty. If your radio station does not seem to be competitive with others in your market,
the cause is usually source material (including excess use of lossy digital compres-
sion), overshoot in the transmission link (including the FM exciter) following the
8700i, or an inaccurate modulation monitor that is causing you to under-modulate
the carrier. A station may suffer from any combination of these problems and they
can have a remarkable effect on the overall competitiveness of a station’s sound.
Section 1 of this manual provides a thorough discussion of system engineering con-
siderations, particularly with regard to minimizing overshoot and noise.

Connection Issues between the 8700i and a PC, Modem, or Network

User Interface Slowdown: The more user presets you make, the more slowly the
8700i will respond to front-panel commands. Delete any user presets you do not
need.

Software Updates: Close any running Windows programs before attempting to
update.

Interrupted Software Updates: If you canceled an update before it completed,
wait at least one minute before attempting your next update.

Software Updates via Modem: If you are updating via the modem, do not change
the “connection type” parameter on the 8700i while the modem is connected or
attempting to connect.

Security Passcode: An A

(administrator) security passcode is required
for upgrading, regardless of whether you are using a Direct, Modem, or Ether-
net connection.

Passcode Format: The passcode is case-sensitive. When entering it into Windows’
Dial-up Connection dialog box, it must be typed exactly as it was originally en-
tered into the Security screen.
