■
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).

Balance is common with all the above deviation adjustments. If Balance (Transmitter Section5) has already adjusted, please skip Step1 and adjust from Step2.
Maximum Deviation (Analog Wide/Narrow) is common with all the analog signaling deviations and CWID Deviation (NXDN Very Narrow). If Balance and
Maximum Deviation (Analog Wide/Narrow) (Transmitter Section7) have already adjusted, please skip Step2 and adjust from Step3.
