FUNCTIONS FOR TRANSMIT
Split frequency operation (Continued)
■
D Split lock function
Accidentally releasing
changes the receive frequency. To prevent this, use
both the split lock and dial lock functions to change
the transmit frequency only. The split lock function
cancels the dial lock function while holding down
during split frequency operation.
RIT
The dial lock's effectiveness during split frequency
operation can be selected in the Set mode for both
receive and transmit frequencies; or only the receive
frequency. (p. 10-10)
When the split lock function is ON, the transmit fre-
quency cannot be adjusted by rotating [DIAL] while
transmitting, even if the lock function is not ON.
Set the split lock function ON in the Set mode.

■ Measuring SWR

The IC-7200 has a built-in circuit for measuring an-
tenna SWR—no external equipment is necessary.
