Designating a Data Master Display
To ensure that the latest system data — such as databases of
waypoints, routes and tracks is available at all multifunction
displays, one of the displays must be designated as the “data
master”.
All system data is managed by the data master. The display that has
been designated as the data master should always be powered-on
— preferably rst, before any additional displays. This is because
every time a change is made to the system data, the data master will
copy its databases to all other displays that are currently powered
on. If the data master is not powered-on, or a data master has not
been designated, an alarm will sound, and you will be prompted to
select a master display.
Note: When changing the designated data master display, or
adding an additional display, ensure that all your data is archived
to a CompactFlash card so that you can restore it later in the
event of a mistake.
Designating the master display
The following task must be performed on the multifunction display
that you want to designate as the data master:
1. Press the MENU button.
2. Using the trackpad, select the System Setup menu item.
3. Using the trackpad, select the System Integration menu item.
4. Using the trackpad, select the Data Master > ON option.
5. Press the OK button.
