3. COMM OPERATION
This section describes the use of the VHF Communication
Transceiver portion of the KLX 135. If you are not yet familiar with
the procedure of turning on and initializing the KLX 135, see
section
4.2 , “Turn-on and Self Test”.
3.1. ENTERING FREQUENCIES
3.1.1. FREQUENCY SELECTION
The KLX 135 is capable of tuning VHF communication frequencies
from 118.000 MHz (megahertz) to 136.975 MHz.
To tune a COMM frequency:
1. Use the left outer knob to select the
desired number of megahertz between
118 and 136. In
figure 3-1 , the
frequency 122.90 MHz is desired.
2. Make sure the left inner knob is pushed in, and use it to complete
the desired frequency. In this case, the left inner
knob changes the frequency in increments of 0.05
MHz (50 kHz) (figure 3-2). Note that the left inner
knob must be rotated three clicks clockwise to go
from 122.75 MHz to 122.90 MHz.
3.1.2. STANDBY FREQUENCY ENTRY
The default frequency entry mode is standby frequency entry. In the
standby frequency entry mode, both the active and standby commu-
nication frequencies are displayed, and any frequency tuning is
performed on the standby frequency.
To tune a COMM frequency using the standby frequency entry
mode:
1. Use the left knobs to tune the standby COMM frequency, such as
122.90 MHz (figure 3-2 above).
2. To exchange the active and standby frequencies,
press the
A
(flip-flop) button (figure 3-3).
