■ Quick split function
When you find a DX station, an important consider-
ation is how to set the split frequency.
When you hold down the [SPLIT] switch for 1 second,
split frequency operation is turned ON, the sub read-
out is equalized to the main readout frequency and en-
ters standby for transmit frequency input.
This shortens the time needed to start split frequency
operation.
The quick split function is ON by default. For your con-
venience, it can be turned OFF in set mode. (p. 12-15)
In this case, the [SPLIT] switch does not equalize the
main and sub readout frequencies.

D Split lock function
The split lock function is convenient for changing only
the transmit frequency. When the split lock function is
not used, accidentally releasing [XFC] while rotating the
main dial, changes the receive frequency. The split lock
function is ON by default, but can be turned OFF in set
mode. (p. 12-16)
