6.5 Security Code (Fig. 30)
A feature with the zone setup of the Grand Concerto System
is the ability to lock the zone. This can be done as a default
that will require a four-digit security code to unlock the
zone Control Pad when the zone is turned on, or it can be
done as a temporary setting from the Control Pad menu to
lock the zone on its current listening choice. In either
scenario, the security code must be set to unlock the zone.
The security code can be any four digits or left at the default
5555.

7. Update System (Fig. 31)
The finished configuration is now ready to be downloaded to
the Grand Concerto amplifier. While downloading, a progress
box will show download progress. Once complete, the
configuration is permanently stored in flash memory.
Configurations can always be retrieved and edited at a future
date.
Control Pad Firmware Update (Fig. 31a)
When first plugged in and addressed, the Control Pads will
poll the main unit for the correct firmware version. If they
are at a lesser version number, an upgrade notice will appear
on the display. It is important to allow this process to
complete. When the Control Pad is finished upgrading itself
it will turn off. At that point, it is ready for zone control use.
