MARKER
• PRINT : The PRINT key is used when the user wishes to make a simultaneous hard copy
of the echogram. This is only possible if a printer is connected to the system.
• MARKER : When the MARKER key is pressed, a vertical dotted line appears on the screen
and moves with the presentation from right to left. At the same time all relevant
information is stored in the system's 24 hour memory. This memory stores data
from the previous 24 system operating hours.
• SYMBOL : The key marked with a loudspeaker symbol is used to acknowledge acoustic
depth alarms.
