Operations and Maintenance Manual
8.4 EXPERT Menu
The EXPERT Menu includes the same sub-menus as the USER Menu described in sub-
section A.2. However, in order to change any settings, the valid Code No. (password) must
be entered. Whenever “CODE NO.” is displayed, it indicates that the valid password must be
entered. This is accomplished by entering code 0000 (4 zeros) by pressing the Program Key 4
times.
As the following Table shows, the EXPERT Menu contains a large number of functions,
particularly in the INSTALLATION Sub-Menu.
