(No.RA012<Rev.001>)1-21
*Note 2:
Only 1 DQT Balance needs to be adjusted (either DQT Balance 1 or DQT Balance 2).
*Note 3:
For the adjustment of the Maximum Deviation (dPMR Very Narrow).
After adjusting the DQT Balance and Maximum Deviation (Analog), it is necessary to adjust the Maximum Deviation (dPMR Very
Narrow).

*Note 4:
(1) Only RX Sensitivity (Semiautomatic) needs to be adjusted (RX Sensitivity does not need to be adjusted again).
*Note 5:
(1) If Analog Narrow band RSSI tuning is selected, Analog Narrow band and dPMR Very Narrow will be adjusted with the same
tuning value.
(2) If dPMR Very Narrow RSSI tuning is selected, it will adjust for the dPMR Very Narrow band only.
