80 FT-857 Operating ManualThe Spectrum Scope Monitor allows viewing of operating activity on frequencies aboveand below your current operating frequency in the VFO mode, or viewing of memory chan-nel activity on the current memory group when in the Memory mode. When the SpectrumScope Monitor is activated, the display indicates the relative signal strength on channelsimmediately adjacent to the current operating frequency.Using the Spectrum Scope1. Set the transceiver to the VFO mode in the desired band, or within the desired memorygroup.2. Press the [FUNC] key momentarily, then rotate the SELECT knob, as needed, untilMulti Function Row “h” [SCOP, WID, STEP] appears on the display.3. Press the [A](SCOP) key momentarily to engage the Spec-trum Scope.4. When the Spectrum Scope is in operation, the relative sig-nal strength of stations on channels immediately adjacentto the current frequency will be indicated on the display.5.
