ADJUSTMENT
L. DCS deviation adjustment 1) Display the �DCS� item. 2) Set the A band as the operation band. 3) Select points f1 to f3 as shown in the �Frequency Adjustment Points� table below. 4) Set the display frequency to the frequency appropriate to the frequency adjustment point. 5) Press [PTT] and turn the encoder during transmission to change the �real-time value�. 6) Press [MNU] key to set the �real-time value� in the EEPROM. 7) Adjust all frequency adjustment points. � If no adjustment is necessary for an item (for example, 50 MHz f2), the following message appears. Operations 5) and 6) are invalid. 96 :�� f2 : � �
