5-3 SIGNALING AND RECEIVE ADJUSTMENT
• Set the specifi ed value using [DIAL], and push [BAND] to store the set value. Then, push [CALL] to move to the next adjustment item.
NOTE:
"DTCS BALANCE" should be adjusted before "CTCSS DEVIATION," and "RX SENSITIVITY" should be adjusted before
"FM/WFM S-METER" (on the next page).
Otherwise, these adjustments will not be adjusted properly.
