Usage
If one of the remotes in a dual system is faulty, the system can be
driven with the other remote. If, however, the ON/OFF key on the
remote-in-charge has a fault, the system does not operate.
If one of the remotes is disconnected from the system when it is
powered down, the remaining remote displays an error (refer to
Flash code 2 in chapter 4.1.1 Error codes and diagnosis codes, page
26) when the system is powered up again to indicate that it was
expecting two remotes in the system. To remove the error, cycle
the power with the ON/OFF key.
