■ About the ∂TX function
The ∂TX function shifts the transmit frequency up to
±9.999 kHz in 1 Hz steps (10 Hz steps when the 1 Hz
step readout is not visible) without shifting the receive
frequency.

1 second.
• If the the Quick RIT/∂TX clear function is ON, push
[CLEAR] to reset the RIT frequency.
r To cancel the ∂TX function, push [∂TX] again.

D ∂TX monitor function
When the ∂TX function is ON, holding down [XFC] al-
lows you to directly monitor the transmit frequency.
✔ For your convenience — Calculate function
The shift frequency of the ∂TX function can be added
to or subtracted from the displayed frequency.
➥ While displaying the ∂TX shift frequency, hold down
[∂TX] for 1 second.

■ About the Monitor function

The Monitor function allows you to monitor your trans-
mit signals in any mode. Use this to check voice char-
acteristics while adjusting transmit audio parameters.
(p. 15-4) The CW sidetone functions regardless of the
[MONI] key setting.
q Push [MONI].
• The Monitor function is turned ON.
• [MONI] indicator above this key lights white.
w Rotate [MONI GAIN] for the clearest audio output
while holding down [PTT] and speaking into the mi-
crophone at your normal voice level.
NOTE: When using the VOX voice delay
turn the TX monitor function OFF or the transmitted
audio will echo.
