OPTIMOD SURROUND PROCESSOR TROUBLESHOOTING
5-7
General dissatisfaction with subjective sound quality
• The 8685 is a complex processor that can be adjusted for many different tastes.
For most users, the factory presets, as augmented by the gamut offered by the
L
ESS-MORE control for each preset, are sufficient to find a satisfactory “sound.”
However, some users will not be satisfied until they have accessed other Modify
Processing controls and have adjusted the subjective setup controls in detail to
their satisfaction. Such users must fully understand the material in Section 3 of
this manual to achieve the best results from this exercise.
• Section 1 of this manual provides a thorough discussion of system engineering
considerations, particularly with regard to minimizing overshoot and noise.
Security passcode lost (when unit is locked out)
• Please see If you have forgotten your “All Access” passcode…on page 2-44.
Connection Issues between the 8685 and a PC, Modem, or Net-
work
• User Interface Slowdown: The more user presets you make, the more slowly
the 8685 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 com-
pleted, 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 8685 while the modem is con-
nected or attempting to connect.
• Security Passcode: An A
LL ACCESS (administrator) security passcode is required
for upgrading, regardless of whether you are using a Direct, Modem, or
Ethernet connection.
• Passcode Format: The passcode is case-sensitive. When entering it into Win-
dows’ Dial-up Connection dialog box, it must be typed exactly as it was origi-
nally entered into the Security screen.
Troubleshooting Connections
• If you get an error message such as “the specified port is not connected” or
“There is no answer”…
