Necessary Deviation adjustment item for each signaling and mode
The following shows the necessary adjustment items for each signaling deviation. Please read the following table like the following
example. In the case of the signaling "QT (Wide 5k/Wide 4k)", this signaling is composed of three elements [Balance, Maximum Devia-
tion (Analog Wide 5k/Wide 4k) and QT Deviation (Wide 5k/Wide 4k)]. Please adjust Balance and Maximum Deviation (Analog Wide 5k/
Wide 4k) before adjusting QT Deviation (Wide 5k/Wide 4k).
