Clockwise rotation of the inner con-
centric OFF/VOL/SQ knob on the
bottom left side turns the receiver/
transmitter on and increases the vol-
ume of the received audio. The outer
concentric OFF/VOL/SQ knob con-
trols the threshold of the received
signal above which the audio is
enabled (or squelch). Turning the
knob clockwise reduces the signal
threshold and decreases the squelch.
The knob on the bottom right side of
the KFS 594 controls setting the
emission modes. Pushing in the
inner concentric knob moves the
cursor, represented by a flashing
digit, from left to right. One push
sets the cursor one digit to enable
that digit to be selected as required.
When this knob is turned, it sets the
digit selected by the cursor. The
outer concentric knob selects the
emission modes. Selecting LSB,
USB, or AM sets the radio to the
corresponding mode and displays a
frequency in the control head, which
may be directly selected on one of
the 19 user programmable channels.
Selecting TEL (AM) sets the radio to
this mode and displays an ITU chan-
nel in the control head.
The STO button is used to perform
four separate functions.
n
In the channel mode, pressing and
holding STO causes the control to
display the letters TX and the
tuned transmit frequency while
the receiver monitors the transmit
frequency, enabling the pilot to
listen for signals on the transmit
frequency duplex channels.
n
Pressing STO while the micro-
phone is keyed broadcasts a 1,000
Hz tone to break the squelch of
some stations.
n
In the program mode, STO allows
the selected frequency to be
entered into the channel appearing
under the CH designation on the
display.
n
Pressing STO clears many error
conditions that are annunciated by
a flashing E for more than three
seconds.
Program any one of the 19 user pro-
grammable channels using the fol-
lowing procedures.
1. Select the channel to be pro-
grammed.
2. Step the cursor to the frequency
digits and set in the desired fre-
quency. Changing the displayed fre-
quency of a programmable channel
automatically places the control
head in the program mode, as indi-
cated by the flashing dash adjacent
to the channel number.
3. Press STO to transfer the fre-
quency into the T/R unit receiver. The
flashing TX appears in the upper
right of the display and the cursor
moves to the 10/1 MHz digits.
4. Change the display to the desired
transmit (if different from the
receive frequency).
5. Press STO again. When the trans-
mit frequency is accepted, the letters
TX and the cursor disappear.
To operate the radio in the directly
tuned mode without a channel num-
ber annunciated or a flashing dash,
tune the channel selector to zero and
then to a frequency. The zero disap-
pears and the annunciated frequency
relocates. Other frequencies may be
selected in a like manner as long as a
channel other than zero is not
selected.
