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.

• The DCS code of each band must be set to a specified value
before entering the service adjustment mode.
• To adjust, switch the DCS ON (ensure to switch it OFF after
adjustment).
• If no adjustment is necessary for an item (for example, 50
MHz f2), the following message appears. Operations 5) and
6) are invalid.
