4.7 DIP Switches
4.7.1 The controls, which are frequently used in the normal operation of the instrument,
are all accessible through the operation menu. Some options, which are
infrequently used or set only once during installation, are located on the back of the
swing-out board in two banks of dip switches. Both banks (S1 and S2) are located
near the upper left corner of the board and consist of 8 switches each. (Refer to
Fig.1)
4.7.2 The DIP switches are scanned only on power-up and every time the instrument is
taken into the menu mode. Therefore, after changes to the DIP switch settings, you
must enter the menu by pressing MENU in order for the instrument to scan the new
switch settings.
