oscillator is not fully warmed up the search may fail. When in AUTO, if
a signal error forces the FS700 to terminate locking, the FS700 will
automatically start a new search. While in MANUAL, a new search
must be started by pressing the EXC key.
Tracking Menu
The first screen has three adjustable parameters and is used to set the
station that the FS700 is to track. If the FS700 is tracking a station,
changing any of these parameters will cause the FS700 to unlock. To
prevent accidental unlocks, a warning message requiring confirmation
of the change will be displayed.
GRI Selection
The first field is the GRI to which the FS700 is to lock. Set the GRI to a
value appropriate to the location of the receiver by referring to the
LORAN chain map to select the GRI for the nearest stations. The GRI
must be set to a value between 40000 and 99990 ms in steps of 10 ms.
Station Selection
Station selection is set with the second field. Adjust this setting with the
up and down arrow keys. The default setting is "AUTO", and the
FS700 will automatically choose the station with the largest signal. The
FS700 may be be set to a specific station - "M" (master), or one of
secondaries. If a chain existed at the chosen GRI when the FS700 was
shipped, the actual station names (a subset of V, W,X,Y, and Z) will be
displayed; otherwise the secondary may be set to an index of A,B,C, D,
or E - the order of transmission of the secondaries. The identification
of the secondaries is determined by the timing of the secondaries
relative to the master station. For a chain not in the FS700's station list
a default set of times will be used- an average of the timings of existing
chains. If the unknown chain's timing differs greatly from typical it may
not be possible to identify and select a particular secondary. However,
the master may always be selected, and AUTO will always select the
largest station- regardless of the identification of the secondaries. This
allows the FS700 to be set to any possible LORAN station, even if it
didn't exist at the time of the FS700's production. Once a station has
been chosen, during AUTO station selection the FS700 will display the
station identification in parentheses after the word AUTO. For
example: AUTO (Y) if Y has been chosen. If the FS700 is set to lock to
a specific station and the master station is not found, the selected
station will not be identified and the search will fail.
The third field is the station location field. This field displays the location
(station name) of the selected station. By scrolling through this list
using the up and down arrow keys a station near the receiver may be
chosen. All stations that existed at the time of the FS700's production
are in this list. If no station exists at the current GRI or station choice
GRI: 99400
