5.1.3. ACTIVE FREQUENCY ENTRY
You can also tune the KLX 135A active frequency directly.
To tune a COMM frequency using the active frequency entry
mode:
1. Press and hold the
A
button for approximately 2
seconds. The standby frequency will disappear and
the active frequency will be the same as before you
pressed the
A
button (figure 5-4).
2. You can now use the left knobs to tune the active COMM
frequency.
3. To change back to standby frequency entry mode, press the
A
button momentarily.
5.1.4. 25 KILOHERTZ CHANNEL SPACING OPERATION
Some communication frequencies are multiples of 25 kilohertz (for
example 125.975 MHz). KLX 135A allows you to easily tune these
frequencies.
To tune a 25 kHz COMM frequency:
1. Pull the left inner knob out.
2. Use the left knobs to tune the frequency. Notice
that the KLX 135A only displays two digits after the
decimal point, so it has to cut off the last digit. For
example, in figure 5-5 the standby frequency is
123.125 MHz and the KLX 135A displays 123.12.
3. When you’re ready to go back to 50 kHz tuning, push the left
inner knob back in. This will allow you to select frequencies with
fewer turns of the knob.
