Pressing the PRESET softkey changes the active preset number. The filter page
settings change as each different preset number is selected. Similarly, the PAGE
softkey changes the filter pages applicable to the selected preset.
IT IS MOST IMPORTANT to understand that the ‘active preset’ is always the filter
that is applied to the NAVTEX message display – even when the preset selection
is not visible.
Presets can be used to switch quickly between different sets of messages filter
selections. For instance, if you want to show ‘weather warnings from all stations in
range’, you can set up a preset number for that specific display.
Tip : Start by using 'preset 1' for normal operation, only use the other presets once you
are familiar with the way presets work and want to switch quickly between different
sets of message selections.
Station Selection
If you leave all NAVTEX stations selected for viewing (subject to your current location)
you may quickly become overwhelmed with NAVTEX messages.
By filtering out unwanted stations, you can greatly reduce the amount of unnecessary
messages that are displayed. Station filtering can be automatic or by manual
selection.
Automatic selection§ can be used if a GPS is connected to the system. The
'in range' stations are then calculated based on the information stored in the
station database.
Manual Station selection is used whenever a GPS position fix is unavailable,
or can be used to override an automatic selection.
