Basically, the maintenance-mode functions listed above should be accessed by service per-
sonnel only. However, you may allow end users to access some of these under the guid-
ance of service personnel (e.g. by telephone).
The user-accessible functions (codes 10, 11, 82, and 91) are shaded in the above table.
Function code 10 accesses the firmware switches WSW01 to WSW34, each of which has
eight selectors. You should not allow end users to access all of those selectors, but you may
allow them to access user-accessible selectors which are shaded in the firmware switch
tables in Subsection 3.3.5.
The service personnel should instruct end users to follow the procedure given below.
(1) Press the FUNCTION key and the MODE key in this order.
The LCD clears the current display.
NOTE: The MODE key is inoperable during standby for redialing, timer, paging, and
forwarding.
(2) Press the 0 key.
(3) Enter the desired function code (10, 11, 82, or 91) with the numerical keys.
