OPERATION
3.2.1 TUNED FREQUENCY DISPLAY
The tuned frequency display is a nine-character numeric display, located at
the top right-hand corner of the front panel. The label FREQUENCY
MHz directly above the display defines its primary function. This display
shows the current tuned frequency, in MHz. Additionally, when numeric
entries are made from the keypad, each keypad entry is displayed in the
entered sequence, as a positive acknowledgment of each key press.
Termination of the keypad entry or pressing the Clear Entry (CE) key
terminates the entry sequence and restores the frequency display.
3.2.2 PARAMETER DISPLAY
The Parameter display, located to the left of the tuned frequency, is an
alpha-numeric display used to perform a variety of functions, based on the
current control mode that is active. Normally, this display provides the
currently active IF bandwidth [BW(kHz)], detection mode [DET], signal
strength [SIGNAL(dBm)], active gain control mode [AGC], BFO offset
[BFO(Hz)] and squelch level [SQL(dBm)], as illustrated in
Figure 3-2
. It
also provides displays associated with memory programming, scan setup,
configuration setup, and step tuning set up operations. As these operations
are activated, the parameter display is replaced with the display associated
with the currently active operation.

3.2.3 TUNING METER (TUNE)
The tuning meter, located directly below the tuned frequency display is a
nine-LED bar display that provides an aid for fine tuning of a signal.
When the receiver is center tuned on a signal, the center LED of this
display is illuminated. As the receiver is tuned above the signal frequency,
the LEDs on the HI side of the display are illuminated, indicating that the
receiver is tuned above the signal. As the receiver is tuned below the
signal frequency, the LEDs on the LO side of the display are illuminated.
