USER-ACCESS TO THE MAINTENANCE MODE

Basically, the maintenance-mode functions listed on the previous page should be accessed by service personnel only. However, you can allow end users to access some of these under the guidance of service personnel (e.g., by telephone).

The user-accessible functions (codes 06, 09, 10, 11, 12, 25, 45, 53, 54, 80, 82, 87 and 88) are shaded in the table given on the previous page. Function code 10 accesses the firmware switches, each of which has eight selectors.
