4.7.1 The controls which are frequently used in the normal operation of the instrument are
all accessible on the control panel. Some switches, which are infrequently used,
are located on the back of the main circuit board.
4.7.2 The DIP switches are scanned only on power-up and every time the instrument is
taken out of the menu mode. Therefore, after changes to the DIP switch settings,
you must bring up the menu by pressing CALL, and then return the instrument to
the online mode by pressing RUN, in order for the instrument to scan the new DIP
values.
