RECEIVE AND TRANSMIT
ï CW pitch control
The received CW tone pitch and monitored CW tone
pitch can be adjusted to suit your preferences (300 to
900 Hz) without changing your transmitting frequency.
q Hold down [SET] for 1 second to enter the Quick
Set mode.
w Push [UP ∫]/[√ DN] one or more times until "CW
PITCH" appears, then rotate the main dial to set
the desired pitch.
ï CW reverse mode
The CW-R (CW Reverse) mode receives CW signals
with the reverse side CW carrier point like that of the
LSB and USB modes. Use this mode when interfer-

mode.
w Hold down [MODE] for 1 second to toggle between
the CW and CW-R modes.
