INSTALLATION ORBAN MODEL
6. Recall Presets
There is a default All-Access passcode:
1234
. This allows PC Remote users to connect
to the 5700i if they forgot to add a passcode from the 5700i’s front panel. Like any
other default passcode, it should be erased and replaced by a strong custom pass-
code as soon as possible.
See To Delete a Passcode on page 2-41 and To Create a
Passcode below. Note that if you fail to create a custom passcode and merely delete
the
1234
passcode, the
1234
passcode will be regenerated automatically the next
time your Optimod is turned off and back on.
The Optimod’s front panel cannot be locked out unless the Optimod has been as-
signed at least one All Access
passcode.
The Optimod secures User Presets by encrypting them (using the Advanced Encryp-
tion Standard algorithm with the session passcode as its key) when PC Remote fetch-
es them. Hence, a packet sniffer cannot intercept User Presets in plaintext form. PC
Remote then writes the fetched User Presets in encrypted form on your hard drive,
where they remain for the duration of your PC Remote session.
If PC Remote exits normally, it will erase these temporary User Preset files
from your computer’s hard disk. If it does not exit normally, these files
will remain in encrypted form. However, the next time that PC Remote
starts up, it will automatically clean up any orphaned files.

.
If the front panel is already password protected, you can only access this
screen by entering a passcode with All Access privileges.
B) Use the four soft buttons, labeled“1,” “2,” “3,” and “4,” to create a passcode.
Passcodes can be up to eight characters long but can only contain the
characters “1,” “2,” “3,” and “4.” This limitation makes it easy to enter a
passcode using the four available soft buttons.
C) When you have finished entering your new passcode, write it down so you do
not forget it. Then press the
Next
button.
If you wish to discard the passcode you just entered, press the E
SC
button
instead. Then return to step (B).
D) The P
ERMISSIONS
screen appears. Turn the knob to choose the permission level
for the passcode you just created.
If you wish to discard the passcode you just entered, press the P
