To make a call using the phone book (MCDU)
The phone directory contains the prioritized subdirectories Emergency,
Safety, Non-safety and Public. Emergency has the highest priority, Safety
the second-highest and so forth. The Public directory is also accessible from
the Full Feature handsets.
To call a number in the phone book, do as follows:
1. Enter the DIRECTORY menu from the main menu.
1. If in latched mode, activate the call by switching on the Mic Switch.
If you select an H+ call priority higher than Public, other calls
with lower priority will automatically be released in case of
congestion in the aircraft system or in the Inmarsat
network.
