FIGURE 5 FRONT PANEL DISPLAY
1) 7-Digit Apha/Numeric Display Readout - This display
indicates frequency, in ‘MHz’ or ‘kHz’ as selected, of the
current VFO or Memory channel. The readout will also
display the channel name if assigned and selected in
addition to various programming and error messages. In
the clock mode, indicates either ‘Local’ or ‘Universal’
time in 24 hour format as selected. Time display is as
follows: HH:MM:SS. Inthe Timer mode, indicates time in 24
hour format as follows: HH:MM, with no seconds indi-
cated.
2) MEM/TUNE - This annunciator indicates the current
memory location. ‘MEM’ will light when the receiver
enters the Memory mode and all memory channel
locations can be sequentially tuned by use of the ‘TUNE
a |_| ‘ buttons or Tuning wheel. With 'TUNE'
displayed, use of the Tuning wheel will allow the the user
to tune away from the selected memory channel.
3) BANDWIDTH/MODE Indicators - The currently selected
IF filter Bandwidth and mode of reception are indicated.
For FM mode operation, only the mode (FM) is displayed.
When ‘AUTO’ is illuminated, the appropriate bandwidth is
automatically set for the corresponding selected mode.
Note: The AGC setting, tuning step size, display resolution
and bandwidth are user programmable and stored per
mode.
The modes are:
AM - Amplitude Modulation
AM/SYNC - Amplitude Modulation (with Synchronous
Detection)
FM - Frequency Modulation
CW - Continuous Wave (Morse Code)
RTTY - Radio Teletype or data
LSB - Lower Sideband
USB - Upper Sideband
4) (SCAN) - The annunciators under this heading indicate
the current scan function programming. (SCAN) willlight
when the receiver enters the (SCAN) mode.
Refer to the ‘Scan Functions’ section of this manual.
IMPORTANT - PLEASE READ
The function lines of the display, described in callouts 5)
through 17) are activated by the unmarked function
button located directly below the displayed function.
The primary function line is the top most line. Pressing the
| * | allows access to the alternate function line (lower
line). Alternate function availability ‘times out’ after any
front panel activity which alters the display.

5) - This annunciator lights to indicate that the alter-
nate function selection is enabled.
6) VFO A/B - This annunciator indicates the VFO in use. A
box! — |appears around the active VFO.
7) A=B - An ‘=’ sign appears between the ‘A’ and ‘B’ ofthe
top function line to indicate that one of the VFO’s has
been setto the same frequency asthe other. Thisfunction
serves as a temporary ‘scratchpad’ memory of the first
VFO frequency as the second VFO frequency is changed
by tuning.
8) PREamp/ATTENuator - A box appears around the
appropriate legend when the Preamp or attenuator is
activated.
9) ANTenna 1/2/VHF-Abox| | appears around the
selected antenna input: ‘ANT 1’, ‘ANT 2’ or the ‘VHF’
C'CONV') connector at the rear panel of the receiver.
NOTE: VHF is only accessible when the accessory VHF
Converter module is installed.
