Some symbols and IDs appear on the advanced-test
menu only when their particular options are attached to
the system unit. If one of these options is attached, and
it's symbol or ID (shown on page 2-11) does not
appear, go to the PIC for that option.
If you see a in the lower right-hand comer of the
advanced-test menu, the menu has another page of
symbols. When the cursor is moved to the last ID on
the screen, moving it again causes this next menu page
to appear.
On the last menu page, a "n" is in the lower right-hand
comer. When the cursor is moved to the last ID on this
screen, moving it again causes the first menu page to
reappear.
