3.2.3
THE
←
(LEFT) AND
→
(RIGHT) ARROW KEYS
The
←
(left) and

The keys have no LED's and are used to move the cursor position in the tuned frequency display. The
following are general guidelines to remember when using these keys.
•
Pressing either
←
or
→
while the TUNE LOCK LED is lit causes it to
extinguish and the tune lock function to be disabled. The cursor in the tuned
frequency display appears in the position to which it was previously set.
•
Pressing either
←
or
→
while the STEP TUNE LED is lit causes it to
extinguish and the Step Tune mode to be exited. The cursor in the tuned
frequency display appears in the position to which it was previously set.
•
The
←
and
→
keys are not functional while the receiver is actively scanning
(i.e. the SCAN key LED is lit and the PAUSE key LED is not lit) or if a
numeric entry is in progress and not terminated.
•
The
←
and
→
keys move the highlighted digit of the tuned frequency display
left and right, respectively, with the following restrictions:
1)
the
→
key has no effect when the highlighted digit is in the 1-Hz
position (far right) of the tuned frequency display,
2)
the
←
key has no effect when the highlighted digit is in the 10-MHz
position (far left) of the tuned frequency display, and
3)
if no digit is present in the 10-MHz position (the tuned frequency is
9.999999 MHz or less) moving the cursor to this position with the
←
key causes a zero (0) to be displayed there.
3.2.4
THE TUNING WHEEL
The tuning wheel is a 2-1/2 inch diameter knob located in the lower right-hand corner of the
front panel. The only function of the tuning wheel is to change the receiver's tuned frequency. The following
are general guidelines to remember when using the tuning wheel.
•
Rotating the tuning wheel clockwise increases and rotating it
counterclockwise decreases the receiver's tuned frequency in increments
corresponding to the cursor highlighted digit in the tuned frequency display.
