Lexicon MC-12 安装指导

User settings will be preserved during the software installation
process, EXCEPT in the following circumstances:

1. The message "WAITING FOR DOWNLOAD" appears on the

on-screen display before the upgrade begins.

2. The computer hard drive does not contain enough available

space to store user settings. About 46kB of space is needed to
store user settings. Additional space is also required. See
the Hardware Requirements section on page 4 for more
information.

3. A communication error occurs when user settings are sent to

the upgraded unit. This might occur if the serial extension
cable is removed, the unit is powered off, or the computer
experiences a problem.

It is recommended to record all user settings on the Installation
Worksheet that begins on page A-12 of the MC-12 User Guide (Rev
1) before beginning the software installation process. This will
expedite the process of reconfiguring the unit in the rare event that
user settings are not preserved.
