filter preset number.
Select the preset that you require for the filter page that you are
viewing and then look at the presets for the other filter pages. Note
that the preset that is displayed is the one that is currently applied to
the message display.
Multiple presets can be used for switching quickly between different
sets of messages on the screen. For instance, if you want to show
just ‘navigational warnings from all stations in range’, you can use a
preset to do this.
Although the presets are pre-programmed, you can set them to any
filter setting you require.
Tip : Use preset 1 for normal operation and only use the other
presets if you want to switch between different sets of messages on
the display.
Station Selection
If you leave your Nav6plus receiving for 72 hours you will have
received many messages (subject to your current location) and
unless you filter out those stations that are not required for display,
you will be swamped with data. This can either be done
automatically using a GPS or by using manual filter settings. In either
case go to [Navtex Mode⇒
⇒⇒
⇒Filter View⇒
⇒⇒
⇒490 or 518 Stns Page]. You
will notice that each station can be set to one of three filter settings:
Setting Operation
On Messages from station always in view (see note 1)
Off Messages from station never in view
Auto Messages from station only viewed when nearest or in
range depending upon setting (see note 1)
note 1 : messages are only displayed if they also fall within the
ageing limit, error limit and message category filter settings.
An asterisk to the right of the station name indicates that the station
is selected with the current filter setting.
