Systems with two Display Heads, you must go to the Head Address Setup
(Figure 28 on page 26) and assign an unique Head Address for each Display Head. Because the factory default
Head Address is set to a “1”, one of the two Display Head’s addresses must be changed to a “2”. Caution!
Failure to do so will cause communication problems which will result in erratic operation.
