■ Necessary Deviation adjustment 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)", this signaling is composed of three elements [Balance, Maximum Deviation (Analog Wide) and QT Deviation (Wide)].
Please adjust Balance and Maximum Deviation (Analog Wide) before adjusting QT Deviation (Wide).
