Scrolling through Memory Data
To scroll the display to a certain time in the memory in order to view events that
occurred earlier (relative to time shown in "time" window), press and hold the
CURSOR
key until nearing the wanted time (shown in the "time" window).
Finely adjust the wanted time by pressing the
CURSOR
or
key momentarily,
each time a key is pressed, the time will advance by a 5 second period.
If the event to be viewed occurred considerably earlier, scrolling can be accelerated
by using the "Page scroll" option. Press the
ENTER
key and the word "Page" will
appear in the window beneath the "Depth Alarm" window. When the
CURSOR
or
keys are now pressed, the display will be shifted by approx. three quarters of a page
backwards or forwards (pressing and holding these keys scrolls continuously).
EXAMPLE:
To view data at the time when "Marker line a" was set, press and hold the
CURSOR
key until the marker line is almost at the right-hand side of the display area. Finally
adjust by pressing the
CURSOR
repeatedly until the marker is at the outer right-
hand side of the display area.
The data will now be presented in the upper part of the display. To move "Marker line
b", press the ENTER key. The word "Page" will appear in the window below the alarm
window showing that the "Page scroll" option is activated. When the
CURSOR
is
now pressed once, the marker line will move to the right. Press the
ENTER
key to
return to the "slow scroll" option and finally adjust as previously described for "Marker
line a".
Depth, scale and position information will not be updated during scrolling
(only time and echograms) except when a marker line passes the right-hand
border of the display area.
The following information can be read off the display for any given time during the
previous 24 system operating hours:
Water depth at that time
Units and mode of measurement at that time
Range in use at that time
Time and date when the information was stored
Whether the NAVIGATION mode was in use at that time
Latitude and Longitude when the information was stored (if connected to a
navigation system)
Whether a shallow water alarm was activated at that time
