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 three sub screens. Setting of the boat (water) speed
damping, switching the depth sounder on and off, and setting the
level of depth damping.
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 12 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
14 20220760I
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.
Depth damping
The displayed depth has four levels (0-3), 0 = Off. On power up
the last set damping is selected. To change the depth damping
level follow the procedure in Figure 2-2, page 12 and select the
wanted damping level.
The higher the figure the more damping.
Screen 2
DEPTH
SPEED OVER GROUND
SEA TEMPERATURE
•The upper screen section displays ‘DEPTH’, as on Screen 1.
•The middle 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 lower screen section displays ‘SEA’, the sea temperature
value and the units, ‘°C’ or ‘°F’.
Screen 2 has two sub-screens: one for setting the depth sounder
on and off and one for depth damping. Refer to above.
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.

Operation of IS15 Combi
20220760I 15
Screen 3 has three sub-screens, similar to screen 1. Refer to
pages 13 and 14.
To Reset the Trim Speed
The Trim Speed may be reset at any time, as per below:
•Select either of the two display screens that show Trim
Speed.
•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).

IS15 General Manual
16 20220760I
Screen 5
SHALLOW ALARM
DEEP ALARM
ANCHOR ALARM
The screen shows the setting of the alarm limits and whether the
alarms are activated or not (On/Off).
The alarms can be set to ON or OFF at any time.
Screen 5 has five sub screens. The first two are for Shallow
Alarm ON/OFF and Shallow Alarm Limit settings. The next two
are for Deep Alarm ON/OFF and Deep Alarm Limit settings.
The last one is for setting the anchor alarm ‘ON’ or ‘OFF’.
SHALLOW ALARM AND DEEP ALARM
The screen displays the Alarm status, ‘ON’ or ‘OFF’, and the set
alarm limit in the order shown.
To turn the alarms ON or OFF and/or set the alarm limits follow
the procedure as shown in Figure 2-2, page 12.
ANCHOR ALARM ON/OFF
Refer to Figure 2-2, page 12 to turn the Anchor Alarm ON or
OFF.
Note ! The anchor alarm should be off when the boat is not at anchor.
The alarm will sound when during a 40 seconds time period
there is a change in the depth of 2-3 meters (6-10 ft.).

2.6 Screen Group 2: Wind
There are three screens in this group.
Screen 1
APPARENT WIND ANGLE
APPARENT WIND SPEED
•The upper screen section displays ‘APPARENT WIND’
•The middle screen section displays a wind direction icon and
the apparent wind angle value.
•The lower screen section displays the apparent wind speed
reading and the unit (e.g. ‘kts’).
Screen 1 has a sub screen for setting the wind data damping.
Wind damping
The displayed wind information has four damping levels (1-4).
On power up the last set damping level is selected.
To change the damping level follow the procedure in Figure 2-2,
page 12 and select the wanted damping level. The higher the
figure the more damping.
Screen 2
TRUE WIND ANGLE
TRUE WIND SPEED
•The upper screen section displays ‘TRUE WIND’.
•The middle screen section displays a wind direction icon and
the True Wind Angle value.
•The lower screen section displays the True Wind Speed
reading and the unit (e.g. ‘kts’).
Screen 2 has three sub-screens. One for setting the wind
damping, one for switching the wind speed alarm on and off, and
one for setting the wind speed alarm limit.
Wind damping
Refer to screen 1.
True Wind Speed Alarm ON/OFF
Refer to Figure 2-2, page 12 to turn the True Wind Speed Alarm
ON or OFF.

IS15 General Manual
18 20220760I
True Wind Speed Alarm limit
Refer to Figure 2-2, page 12 to set the wind speed alarm limit (0-
99 knots).
Screen 3
WIND DIRECTION
The screen displays the Wind Direction in degrees and the unit
(‘T’rue or ‘M’agnetic). Refer to page 20.
Screen 3 has a sub screen for setting the magnetic variation.
Refer to page 21.
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 20).
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.
