Control ID
Control ID selection allows units placed in close proximity to one another to have differ-
ent IR transmissions so only one unit is controlled at a time.
Assigning or Changing the Control ID:
(Available only when the optional remote control NP02RC is used)
1. Display the current control ID on the Control ID screen.
2. Press one of numeric keypad buttons while pressing and holding the ID SET button

trol. To set "No ID", enter "000" or press the CLEAR button.
