ZOOM MARKER
The zoom marker appears in the normal,
bottom marker and bottom zoom displays
and marks the area which is expanded in the
bottom marker and bottom zoom pictures.
You can turn on/off the marker as desired.
SPEED ADJ.
If the speed sensor-generated speed
indication is wrong, you can correct it here.
(NMEA format speed data cannot be
adjusted.) For example, if the speed
indication is 10% lower than actual speed,
press ▲ to display +10.
TEMP ADJ.
If the water temperature sensor-generated
water temperature indication is wrong, you
can correct it here. (NMEA format water
temperature data cannot be adjusted.) For
example, if the water temperature indication
is 2° higher than actual water temperature,
press ▼ to display -2.0.
DEPTH ADJ.
Set the ship’s draft, to show the depth
between the sea surface and the bottom

LOCAL TIME OFFSET
GPS uses UTC time. If you would rather use
local time, enter the time difference between
it and UTC time. Use the +<-->- soft key to
switch from plus to minus and vice versa.
GEODETIC DATUM
Your equipment is preprogrammed with most
of the major chart systems of the world.
Although the WGS-84 system, the GPS
standard, is now widely used other
categories of charts still exist. Select the
chart system used, not the area where your
boat is sailing. The default chart system is
WGS-84.
