The instrument is operated by five buttons. By pressing one of
the arrow buttons you can move up, down, or sideways through
the selection of display screens that are available. The table of
screens is shown on page 9. The reset button is only active on
some of the screens. When a button is pressed a beep will
confirm the operation.
The display is divided into three sections, each section normally
containing one set of information. On some screens a graphical
display may cover more than one section.
2.2 Powering Up
When the instruments are powered up for the first time, see
section 7.1. ‘First time turn on’ on page 73.
At normal power up, each instrument shows the start-up screen
with the software version for approximately two seconds. The
display will then change to show the screen that was on at turn-
off.
2.3 Display backlighting
Press the button and hold for 2 seconds. The display then
presents the backlighting level. Repeat pressing until desired
backlighting level. Selectable values are 1-7 and off (0).

2.5 Screen Group 1: Depth, Speed, Trip Log
There are five screens in this group (all have one or more sub
screens).
Screen 1
DEPTH
BOAT SPEED
TRIP LOG
•The upper screen section displays ‘DEPTH’, unit (e.g. ‘mtrs’)
and the depth value. An arrow indicates a rising (↑) or falling
(↓) bottom. A bargraph indicates the strength of the signal.
‘EXT’ replaces the bargraph if the depth signal is from an
external source on NMEA format.
•The middle screen section displays ‘BOAT’, unit (e.g. ‘kts’)
and boat speed value.
•The lower screen section displays ‘TRIP’ and the trip log
value in nautical miles.
Note ! If the system depth transducer signal is lost, the Depth display
will flash the last good echo value for one minute, then it will
show ---. If there is an alternative depth input to the system on
NMEA format and the sounder is set to Off, this depth will be
displayed instead.
Screen 1 has two sub screens. One for setting the boat (water)
speed damping, and one for switching the depth sounder on and
off.
Speed damping
The displayed speed has four damping levels (0-3), 0=Off.
On power up the last set damping level is selected.
To change the speed damping level follow the procedure in
Figure 2-2, page 10 and select the wanted damping level. The
higher the figure the more damping.
To Set the Depth Sounder On or Off
In certain circumstances, e.g., to save power in known waters or
when out of depth range, you may want to turn the depth sounder
off. It is also recommended to turn it off if there is another
sounder on board operating on the same (200 kHz) frequency.
Interference between the two can thus be avoided.

IS15 General Manual
12 20220760G
Note ! When the sounder is turned off, the display will show OFF
instead of the depth reading.
Follow the instructions in Figure 2-2 to access the depth sounder
ON/OFF screen. With the ON-screen flashing select OFF and
return to Screen 1 as per instructions.
This setting is not affected by power off/on or a Communication
Reset, but defaults to ON after a Master Reset.
Screen 2

value and the units, ‘°C’ or ‘°F’.
Screen 2 has a sub-screen for setting the depth sounder on and
off. Refer to page 11.
Screen 3
TRIM SPEED
DEPTH
•The upper screen section displays ‘TRIM’ and the unit, e.g.
‘kts’. The Trim Speed is the difference between the present
boat speed and the target speed.
•At turn on the Trim Speed will only be indicated if it has
been reset (see below), until that time it will show ‘----’.
•The lower screen section displays DEPTH as on screens 1
and 2.
Screen 3 has two sub-screens. One for setting the water speed
damping, and one for switching the depth sounder on and off.

•A short press of the (Reset) button will set the target
speed as the current speed. The trim speed displays will then
show changes from the current speed.
Screen 4
SPEED OVER GROUND
BOAT SPEED
BOAT AVERAGE SPEED
BOAT MAX SPEED
•The upper screen section displays ‘SOG’, the unit (e.g. ‘kts’)
and the Speed Over Ground value. SOG will only be
displayed if a GPS receiver input is available.
•The second screen section displays ‘BOAT’, speed value and
the unit (e.g. ‘kts’).
•The third screen section displays ‘AVG’, average speed value
and the unit (e.g. ‘kts’). The average speed is calculated as
the distance covered by the boat since power up or when the
passage time was last reset, divided by the passage time.
•The lower screen section displays ‘MAX’, maximum speed
value and the unit (e.g. ‘kts’).
Screen 4 has a sub-screen for setting the water speed damping.
Note ! Average speed and max speed are reset by Passage Time reset
(See paragraph 2.9).
Screen 5

Screen 3 has a sub screen for setting the magnetic variation.
Refer to page 19.

IS15 General Manual
16 20220760G
Notes ! 1. The Wind Direction is calculated from available heading
data. The wind direction given is the effective wind direction
over the water. The display will be most accurate after a
period on one heading, however, it will respond rapidly to
course changes.
2. If there is no heading data, but Course Over Ground (COG)
data is available then the Wind Direction is calculated from
the Course Over Ground. In this case there is compensation
for the tide, and the wind direction given is the effective wind
direction over the ground. However the display will not be
accurate after a course change, and will require a period on
one heading before it is correct. (Any errors in the
Navigation Receiver’s fix will degrade the accuracy of the
wind direction.)
3. The Wind Direction is referenced to either Magnetic or True
North as selected for the heading. The data can be converted
from one to the other if the local magnetic variation is
available (page 19).
4. Note that the ‘TRUE’ and ‘APPARENT’ readings that are
shown in this group of screens relate to the Wind Speed and
Angle, and not the Wind Direction.
2.7 Screen Group 3: VMG
There are three screens in this group.
Screen 1

BOAT SPEED
APPARENT WIND ANGLE
•The upper screen section displays ‘VMG’, the VMG to wind
value and the unit (e.g. ‘kts’). The VMG display shows the
Velocity Made Good into the wind, this is shown as a
positive speed if the vessel is travelling upwind, and as a
negative speed if the vessel is travelling downwind.
•The middle section displays ‘BOAT’, the Boat Speed reading
and the unit (e.g. ‘kts’).
•The lower screen section displays ‘WIND APP’, a wind
direction icon and the apparent wind angle reading.
