(1) Function mode: Displays the currently selected display (Spectrum, Bar graph, and Counter)
(see page 23)
(2) Scan mode: Displays the selected scan mode.3 types of scanning may be selected. See page
14 and 26 for manual scan, pages 17& 26 for search and pages 16 & 26 for channel scan.
(3) Title name: The data memory, which is, selected (page 37)
(4) Marker Frequency: The frequency in which the unit is currently tuned to as indicated by the
marker indicator.
(5) Ref.Level: The base line reference amplitude(0 level). The Reception modes (page 50)or the
selected external Attenuator value (page 46)sets this value.
(6) Marker Level: The amplitude value of the signal level the unit is currently tuned to as indicated
by the marker.
(7),(8) Center Frequency and Span are used in Manual scan and are described on page 14.
(9) Step Frequency: The scanning frequency increment value set by the .(page 49)
(10) Reception Mode: The type of modulation needed for aural reception of the incoming signal.
Note: a CW or a signal other than a Narrow Band FM(NBFM), wideband FM(WBFM), AM or SSB
may be displayed by selecting a reception mode which has the appropriate bandwidth
(see page 5).
The Reception mode is selected by pressing the button.
(11) Sweep Mode: Determines how the scan moves across the screen when the squelch is activated.
(See page 26)
(12) Displays the value of the squelch level (see page 51).
(13) Marker: Indicates the signal level currently being scanned
(14) Attenuator Value: Displays the amount of external attenuation connected to the input. When
an external Attenuator is used, the value of the Attenuator must be added to the Reference
level. This is accomplished through the ATT dB set in the system
