NOTE: In the digital output test mode, each component is actuated using the DO TEST menu
and deactuated using the STOP DO TEST menu. Therefore, to deactuate an actuated compo-
nent, you must first go back to the STOP DO TEST menu and select the component again. If
multiple codes are stacked, components should be deactivated in the sequence in which they
were switched on.
The following table lists the digital output codes.
