"Menu" steps to the next menu on the same level. Pressing "Enter" goes
down one level, or if at the lowest level saves current value in non-
volatile memory. Pressing "plus" or "minus" changes the content for the
current menu.

more.

experts only. To access these menus the access level must be changed
from "All Users" to "Authorised Expert".

enter. The "Authorised Expert" access level shall only be used by
