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)”, 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 Section 3) has already adjusted, please skip Step 1 and adjust
from Step 2.
• Maximum Deviation (Analog Wide/Narrow) is common with all the analog signaling deviations and CW ID Deviation (NXDN Very Narrow).
If Balance and Maximum Deviation (Analog Wide/Narrow) (Transmitter Section 5) have already adjusted, please skip Step 2 and adjust from Step 3.
