(2) OPERATING FREQUENCY SELECTION
1) To select the desired operating band, see (1) BAND
SELECTION on the previous page.
2) Rotate the MAIN DIAL to set the desired operating
frequency.
e The frequency changes in 10 Hz steps.
eTo change the frequency either in 20 Hz or 50 Hz
steps, see (3) CHANGING THE FREQUENCY STEP.
e To change the frequency quickly, see step 3.
e Faster MAIN DIAL rotation automatically shifts the
tuning increment by 10 KHz per full rotation.
eWhen the [kHz] switch is pushed, "~>" appears
above the kHz digit. Rotating the MAIN DIAL
changes the kHz digit. | `
Push [kHz].
This digit and the above
digit change.
eWhen the [MHz] switch is pushed, "~" appears
above the MHz digit. Rotating the MAIN DIAL
changes the MHz digit.
Push [MHz].

~" appears.
This digit and the above digit change.
(3) CHANGING THE FREQUENCY STEP
The 1C-725 has been set at 10 Hz frequency steps at the
factory. However, the frequency step can be changed to
20 Hz or 50 Hz as follows: ©
1) Push the [FUNC] switch.
PRE-OPERATION 4
2) Push and hold the [kHz] switch, then rotate the MAIN
DIAL.
e The FUNCTION DISPLAY shows frequency steps for
10 Hz, 20 Hz and 50 Hz sequentially.
3) Select the desired frequency step and release the [kHz]
switch.
(4) TURNING ON AND OFF THE 10 Hz DIGIT
The 10 Hz digit can be turned ОМ-апа OFF. The frequency
changes in the set frequency step even if the digit is turned
OFF.
1) Push the [FUNC] switch.
2) Push the [BAND] switch.
e The 10 Hz digit disappears.
Disappears.
3) Push the [FUNC] switch then push the [BAND] switch
to turn ON the 10 Hz digit.
e The 10 Hz digit appears again.
= Appears again.
4-3 VFO A AND VFO B SELECTION
The 1C-725 contains two VFOs which both receive and
transmit. The VFOs are called VFO A and VFO B. This
dual VFO system provides tremendous operating flexibility.
Push the [VFO] switch to select VFO A or VFO B.
