1.22 The FUNCTION key
The FUNCTION key works similar to the auto-
matic dialing feature on a telephone, playing back
controls settings just as they were registered. In-

navigation in a harbor, for example, you can have
the FUNCTION key do it for you.

objectives available are outlined in the table which
follows.

Display
The MARK (PUSH) control inscribes marks on
the display. Each time the MARK (PUSH) con-
trol is pressed, an asterisk (*) appears at the cur-
sor location. You can inscribe 20 marks on the
display to denote important locations such as
wrecks and fishing grounds, or mark radar tar-
gets when changing the range. When the memory
for marks becomes full, the eldest mark is erased
to make room for the latest.
Inscribing marks
Place the cursor on the location desired for a mark
and press the MARK (PUSH)
control.
