Figure 9-1. The Markers Group
There are ten markers: MO through
M9.
Any combination of these may
be on at one time, and they may be set to a frequency anywhere in the
instrument’s current frequency range.
When the instrument is preset (factory mode), the values of all of the markers
are set to the center frequency of the instrument’s frequency range. When a
marker is first turned on, its initial value will be either the preset value or the
last value it was set to.
If a marker has been previously set to a value outside the range of the current

of such a marker using the front panel knob or the
@J
&J keys, its value is
