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.
20220760L
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.

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.
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
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.

• The lower screen section displays the water depth reading.
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.
Note !
20220760L
Screen 1 has two sub screens. One for switching the depth sounder on and off and one for setting the depth damping.
Depth Sounder On / 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.
When the sounder is turned off, the display will show OFF instead of the depth reading.
Follow the instructions in Figure 3-2, page 32 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 will default 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 3-2, page 32 and select the
wanted damping level.
The higher the figure the more damping.

V1R2: First production version
V1R3: Upgraded version with added features.
• Trip log replaces sea temperature on first screen of IS15
Combi.
• In Locked Course mode the LCD on IS15 Compass has been changed to show deviation in degrees from locked course.
• Improved log calibration procedure. Possible to set Log reading as percent (%) of default value. Log calibration can be set to same value on identical boats.
• Boat speed always reads 0.0 at zero speed. (V1R2 may show
- - - at turn on and a ‘residual’ speed value when slowing down to zero speed).
• Improved boat speed and wind speed damping.
• Improved damping of heading displays.
• Depth transducer remains OFF at turn on if it was set to OFF while the system was running.
• Test screens added to Installation Menu to simplify trouble shooting.
• Roblink can be turned off and thus eliminate a possible interference when a single instrument is connected as NMEA repeater.
• ‘Communication reset’ added. Saves all settings in the event an anomaly in the system functions calls for a reset.
V1R4: Substitutes V1R3 that contains a bug. V1R3 should not be used.
V1R5: Upgraded version with added features.
• Two new display screens in Display group 4, Nav. Screen 1 shows heading, boat speed and rudder angle. Screen 5 shows waypoint bearing and COG. Screen order has been altered.
• Two new screens in the Installation Menu Group 8, Rudder.
Screen 1 shows rudder angle offset and screen 2 shows rudder angle source.
• New Setup screen for Depth damping in Screen group 1.
• Default depth offset change from –0.3 m to 0.0 m.
Technical Specifications
• Increased damping of wind display at level 2, 3 and 4.
• Increased damping of boat speed at level 2 and 3.
• Instruments output True Wind Angle and Speed in addition to Relative Wind Angle and Speed.
• NMEA depth sentence ‘DBT’ added.
• Access to all offset adjustments when the instrument is used as NMEA repeater.
• Corrected a bug in the UTC offset.
• New NMEA In/Out screen in the Installation Menu Group 1
General. Allows you to manually change the NMEA ‘talker’ port to a ‘listener’ port.
V1R6: New software to comply with PCB Ass’y Revision H (B on round heads) onwards. V1R6 is backwards compatible with previous software and hardware versions.
Notes!
1. PCB Ass’y with this revision does not accept V1R2 or V1R4 software.
2. On IS15 Combi, V1R6 should replace V1R5 if the display turns pale in bright sunshine.
3. V1R6 is backward compatible with V1R2 and V1R4.
However, anomalies may be observed if attention is not being paid to the NMEA interface. In systems with mixed software, do not interface NMEA ‘talkers’ to heads with
V1R2 software.

6.4 IS15 Transceiver Mounting
The IS15 Transceiver is not weather proof and should be mounted vertically in a dry place with the cable outlets pointing downwards.
The unit is mounted to bulkhead or panel by four screws through the mounting lugs.
Installation
6.5 Transducers
Follow carefully the instructions that come with the speed/temp. and depth transducers.
Mounting Guidelines
Depth Transducers
• The main source of the vessel generated noise is the propeller.
• The deeper the transducer projects the lower the risk of aerated water.
• On displacement hulls place the transducer 1/3 aft along waterline.
• Avoid locations near the keel or bow due to aeration.
• Mount the transducer on the side of the hull where the propeller is moving downward.
• On sailboats mount forward of the fin keel, with minimum dead rise.
• On planing vessels mount aft near the keel to insure water contact at high speed.
• On I/O’s mount close to the engine.
• On inboards mount well ahead of the propeller.
• On higher speed vessels (+27 knots) mount in known good locations.
• Do not mount near water discharge or behind struts or fittings, which will create turbulence.
• For dead rise greater than 10 degrees a fairing is recommended.
Speed Transducer
• On sailboats the sensor should be mounted close to the centerline and 12 to 24” ahead of the keel.
• On displacement vessels the paddlewheel should be mounted well aft so the sensor is always in contact with the water.
• Do not position the paddlewheel directly ahead of a depth transducer.
• Do not locate the speed sensor behind struts or thru-hull fittings.

6.6 Cabling
Note !
Figure 6-5 Interconnection – Principle diagram
Choosing the Cable Routes
After you have decided on the system and mounted the components of the IS15 System, the next step is to route the cables between the various parts of the system and to the power supply. Choose the most direct paths while avoiding the following hazards:
• Sharp bends or kinks in the cable
• Hot surfaces (exhaust manifolds or cooking equipment)
• Rotating or reciprocating equipment
• Sharp or abrasive surfaces
• Door and window jambs
• Corrosive fluids or gases
Total length of Roblink cables
The IS15 Transceiver can drive a total of 7 instrument heads.
They can be connected in one single “daisy chain” with the
Transceiver in one end, or in two chains with the Transceiver as a link. The total length of all interconnecting Roblink cables
should not exceed 30 m as shown on Figure 6-6.
The length of the masthead cables shall not be included in the above.

See page 6 ‘Optional equipment’.
Securing the Cables
After the ideal cable routing has been established, use tie-wraps,
‘P’ - clips or other fixings to secure the cables along the routings.
To prevent chafing add protection for the cable jackets where the cables pass through bulkheads, or past sharp edges.
Secure the cable near the terminals for strain relief. See also
Secure the cable ends with enough slack to allow for easy connection / disconnection with the instrument removed from its location.
Cut any spare wire ends to an appropriate length.
67
IS15 General Manual
Securing the connectors
It is recommended that for extra security you secure the connectors with the enclosed self-tapping screws.
Figure 6-7 Securing connectors to the instrument
Make sure that all empty sockets have the protection plugs inserted. Coat the connectors with silicone grease or petroleum jelly. These products will not harm the instrument.
6.7 Instrument head connections
Caution !
Figure 6-8 - Instrument Connections
The instrument head has four identical two-pin connector sockets protected by rubber plugs. Each socket is identified by number and signal markings.
NMEA cable must be plugged into connector no. 4. Wrong connection may damage the connected equipment.
Installation
Interconnections
Connection between the instrument head and the IS15
Transceiver is made by the 10 m (33’) Roblink cable supplied with the Transceiver.
Connect the Roblink cable between one of the three Roblink sockets on the IS15 Transceiver and the PWR-ROBLINK socket
(1) on the display head.
Interconnection between instrument heads is made by the
supplied 0.3 m Roblink cable. Refer to Figure 6-5
Interconnection diagram on page 66.
6.8 NMEA connections
General
Note ! The NMEA port on the IS15 instruments is unidirectional, i.e. it is automatically configured for input (listening) or output
(talking). Thus you will need a minimum of any two instrument heads to make the system both ‘listen’ and ‘talk’ (I/O).
Roblink cables have to be ordered separately for NMEA

6.9 IS15 Transceiver
This unit contains the depth and the speed/temperature electronics. The power supply (battery) and the transducers are connected to the unit.
The unit has three Roblink connectors for instrument heads and wind transducer.
Speed/temp transducer and depth transducer are hard-wired to plug-in screw terminals on the PCB (pwr terminal is fixed).
• Remove the top cover to get access to the plug-in terminals.
• Press the cable end through an appropriate recess in the
gasket (ref. to Figure 6-5). Remove about 2 cm (0.8”) of the
cable insulation.
• Pull out the plug-in terminal before connecting the wires.
• Be careful to prepare all wires on each cable before putting it through the gasket to avoid strands getting onto the PCB.
• Insulate the shields by electrical tape or similar.
• Make the connections according to the following connection diagrams.
• Leave sufficient free wires so that the plug-in terminals can be easily connected/disconnected.
• Ensure that no strands are left inside the unit before putting on the cover.

Figure 6-17 Depth Transducer connections
When installing Airmar depth transducers with a 200KHz-G designator, a 2 Kohm resistor should be connected across the terminals as shown. The resistor provides a better impedance match to the particular element used in these transducers, hence erratic readings are avoided in very shallow waters.
The P52 and the SS505 listed by Simrad have a 200KHz-G designator and will need the 2 Kohm resistor. Other Airmar depth transducers listed by Simrad have a 200KHz-U or 200KHz-B designator.
Figure 6-18 Speed/Temp Transducer connections
Installation
Power connection
There is no power cable supplied for the Transceiver. Use a cable with minimum wire gauge of 1.5mm
2
(AWG14). The outer diameter should be 10 mm (0,4”) to ensure a tight fit through the gasket.
Connect the Power cable to TB1 on the IS15 Transceiver PCB and the other end to a circuit breaker.
The connection is polarity protected and monitored by a green
LED. If a red LED is lit on the PCB, swap the supply wires (see
6.10 IS15 Instruments as NMEA repeaters
Figure 6-20, Figure 6-21 and Figure 6-22 are examples of how
IS15 instruments can be used as NMEA repeaters. Depth, speed and temperature can be displayed when connected to a Simrad
CEXX Chart plotter/Echo sounder or CAXX Multifunction radar. Any preferred combination of instruments can be used, the
IS15 Combi for example is an excellent display also for wind data presentation.
Installing the Roblink Power Cable
The configuration in Figure 6-20 is limited to a total of 3
instruments and a Roblink Power Cable (P/N 22093587) is required to enhance the Roblink signals. Connect the cable to a circuit breaker. Extend the cable if necessary using a wire gauge of 0,75 mm
2
(AWG18).
Notes !
1. If an IS15 Wind Transducer is connected to the IS15 instruments when using this configuration, it must be plugged into connector no. 2 (Roblink) on instrument head no. 3. Refer to note 2 for NMEA connection.
2. If only a single instrument is installed (Figure 6-22) there is
no need for the Roblink Power Cable. Simply cut the 0,3 m
(1’) cable that comes with the instrument in two and extend the halves to the 12V supply and the NMEA source respectively using twisted pair cable. – Also refer to
instructions for Roblink turn-off (paragraphs 7.3 or 7.13.)

Note !
Figure 6-26 IS15 Expander – Connector and terminal locations
Refer also to Figure 6-17 and Figure 6-18
Power connection
There is no power cable supplied for the Expander. Use a cable with minimum wire gauge of 1.5mm
2
(AWG14). The outer diameter should be 10 mm (0,4”) to ensure a tight fit through the gasket.
Connect the Power cable to TB1 on the IS15 Expander PCB and the other end to a circuit breaker. Use a 5 Amp fuse in the line.
The connection is polarity protected and monitored by a green
LED. If a red LED is lit on the PCB, swap the supply wires (see
NMEA connections
General
The IS15 Expander has two sets of NMEA I/O ports. TB5 and
TB6 are input and output ports no. 1 respectively and TB11 and
TB7 input and output ports no. 2 respectively.
Always use twisted pair cables for NMEA data.
Installation
The NMEA “listeners” must be connected to either TB6 or TB7.
Notes !
Figure 6-27 NMEA out
Figure 6-28 NMEA in
The NMEA “talkers” must be connected to either TB5 (GPS) or
TB11 (Autopilot and other). The IN ports are non polarized (colour independent).
1. The NMEA input ports are dedicated, i.e. port no. 1 is for
GPS/Plotter data and port no. 2 for other data. Refer to the
NMEA table on page 56 to identify which signals (GPS_Data
and Nav_Data) and corresponding NMEA sentences that should be connected to TB5 (port 1).
2. As a rule of thumb, the GPS/Chartplotter should be connected to TB5 (input) and TB6 (output), whilst the autopilot should be connected to TB11 (input) and TB7 (output).
3. Please observe the following:
− IS15 will read depth on NMEA provided the IS15 depth sounder is turned off.
− IS15 will read wind speed and angle on NMEA when there is no wind transducer connected.
− IS15 will not read water speed and temperature on NMEA when there is an IS15 Expander (or IS15 Transceiver) in the system.
4. The output ports (TB6, TB7) are outputting parallel data and each port can drive two NMEA “listeners”.

IS15 General Manual
Interfacing to a Simrad AP11 or AP 20 series autopilot
Use a single cable with two twisted pairs of wire for this connection.
NMEA Out
The connection will provide speed, depth, temperature and wind data input to the autopilot.
With a J3000X Junction Unit in the system the autopilot will also receive GPS data via this connection provided a
GPS/chartplotter is connected to the Expander.
The connection is made to the J3xx Junction Unit Main Board,
Terminals RX1+ and RX1-.
NMEA In
This connection provides heading data input to the instruments.
The connection is made to the J3xx Junction Unit Main Board terminals TX1+ and TX1–.
Note !
Figure 6-29 Simrad Robertson “X” series autopilot connection
With a J300X Junction Unit in the autopilot system you may have redundancy and a higher heading output rate if you run a separate and direct NMEA interface between the chartplotter and the autopilot.
In that case connect the IS15 Expander to J300X, RX2/TX2 instead. Connect the chartplotter (port 1) to IS15 as shown in
Figure 6-12. In addition connect the chartplotter (port 2) to
J300X, RX1/TX1. On the autopilot and the chartplotter the interfacing must be set up accordingly.
Installation
Connecting a Simrad XX32/XX40/XX50 series
GPS Plotter
Use a single cable containing two twisted pairs of wires if you need to extend the cable(s) that comes with the equipment.

Installation
Setting-Up
Follow the instructions in Section 7 and in the IS15 Wind
Manual, section 6.
Expanding the system
You may add another 7 instruments to an IS15 system that
contains an IS15 Expander. Please refer to Figure 6-34 and
observe the following:
• The Main system is powered by the Expander
• The Secondary system is powered by an IS15 Power Supply
• The two systems are interfaced on NMEA using a single
Roblink cable between the two
• The Secondary system is a repeater system to the Main system
• All sensors are connected to the Expander
• All NMEA interface to peripheral equipment is to the
Expander
Please observe:
1. All system units should be the latest version.
2. The Power Supply has a 5m (16’) Roblink cable as standard.
3. If you need to extend the cables, please order standard IS15 cables and the cable adapter (joiner) as per our price list and
observe the max. cable lengths as per Figure 6-6. Maximum
recommended (NMEA) cable length between Main and
Secondary system is 70 m (230’).
4. Plan your installation so that heads from the two systems are not placed adjacent to each other. You may notice a minor delay in response between the Main and the Secondary system depending on the type of information you are reading. This is caused by the transfer time on NMEA format.
5. When commissioning, start with the Main system, then duplicate on the Secondary system, i.e. first time turn-on, units, off-sets, illumination bank, etc. Perform the calibrations using the Main system and then enter the calibration values into the Secondary system.
6. Normal operational settings, e.g. depth alarms, damping and illumination must also be set on both systems.
7. You can only turn off the IS15 depth sounder from the Main system.

7.1 First time turn on
Note ! Always turn on all NMEA “listeners” and “talkers” connected to the system before the first time you turn on the IS15 system.
This includes turn on after a COMMUNICATION RESET or a
MASTER RESET. The system will then automatically configure the IS15 NMEA ports as talkers (NMEA out) or listeners (NMEA in).
Before leaving the factory a Master Reset has been performed on all instruments. The first time power is applied to an instrument, the display will prompt you to press the illumination key.
To assign an instrument to a system, press the button. In a multiple instrument system the instruments are assigned and given an Id number in the same sequence as the buttons are pressed. The instrument that is assigned as #1 will be the master unit and broadcast common set-up information on the Roblink to the other instruments.
Notes !
1. When assigning more than one instrument to a system, allow an interval between each assignment, while the instruments read “Please Wait”.
2. With an Expander in the system this will always have Id no.
1, i.e the first instrument to be assigned will then be Id no. 2.
After having assigned all instruments in the system, turn the power Off and then On (the instruments will display POWER
OFF [P.OFF] if you forget). The system will now display the start-up screens.

2. Press the button and hold for 2 seconds to access the screens in the General Screen Group.
Screen 1
ILLUMINATION BANK
The IS15 instrument system can have two separate illumination banks of instruments. Setting the lighting level on one display will set all the other displays in that bank to the same level, but will not effect any displays in the other bank. For instance, the lighting level can be independently controlled for:
• The cockpit and chart table instruments of a yacht.
• The cockpit and mast instruments on a yacht.
• The cabin and flybridge instruments of a motor yacht.
Note ! You can also have individual lighting on all instruments. Then the illumination bank setting must be 0.
Screen 2
CONTRAST
The LCD on IS15 Series instruments can be set to one of eight contrast levels to best suit the viewing angle of the particular installation.
The default level (level 4) is suitable for a wide range of viewing angles and will probably not require alteration. However, view the display from different angles and adjust if required. In twilight or in the dark use appropriate illumination when adjusting the contrast.

SHOP MODE
The instrument has a demonstration mode that can be activated by selecting ‘Shop Mode’ On. This function is very useful for dealers when they want to demonstrate the IS15 system or when it is put on display on a show. The Shop Mode is turned off when power is turned off.
When in Shop Mode the instruments will display external data if data is available as input from sensors.
Screen 4
NMEA IN/OUT
This screen allows you to manually change the NMEA ‘listener’ port = NMEA IN to a ‘talker’ port = NMEA OUT, or vice versa.
Hence you need not make a Master reset or a Communication reset. Refer to chapter 7.1 First time turn on. See also note below.
The setting is local to each instrument.
If there is an active ‘talker’ connected to the NMEA port, you will not be able to change this port from ‘IN’ to an ‘OUT’ port unless the ‘talker’ is disconnected.
Screen 5
ROBLINK ON/OFF
This screen allows you to turn the Roblink Off (or On). The setting is local on each instrument.
Notes !
1. The Roblink must be turned Off when the instrument is used as a single NMEA repeater. However, if more heads are connected as NMEA repeaters in a daisy chain the Roblink must be On.
2. When the Roblink has been turned Off it will not default to
ON even after a Master Reset. If required it must therefore be turned On again using the procedure above.

ILLUM. BANK [bAn.1]
The display reads bAn.0 – bAn.2
The IS15 instrument system can have two separate banks of instruments. Setting the lighting level on one display will set all the other displays in that bank to the same level, but will not effect any displays in the other bank. For instance, the lighting level can be independently controlled for:
• The cockpit and chart table displays of a yacht.
• The cockpit and mast displays of a yacht.
• The cabin and fly bridge of a power boat.
Note !

Setting-Up
You can also have individual lighting on all instruments. Then the illumination bank setting must be 0.
Screen 2
COMPASS CALIBRATION [CAL.C]
This function will activate the automatic compass calibration procedure.
Do not use the calibration procedure when the IS15 instruments are connected to a Simrad autopilot.
Before you begin the compass calibration procedure, make sure you have enough open water around you to make a full clockwise turn. Let the boat turn at idle engine speed.
1. Begin turning the boat to starboard.
2. Press the button and hold for 2 seconds. The LCD flashes
‘rUN’ and then ‘CAL.C’.
3. When the calibration is completed, (after having made approximately 1 ¼ turns), it will be confirmed by the display reading ‘doNE’.
Screen 3
HEADING OFFSET [OFFS]
Do not use the Heading Offset procedure when the system is connected to a Simrad autopilot.
The Heading Offset feature allows you to correct for a permanent heading offset that may be present as a result of the compass being installed with a lubber line offset, or a fixed offset remains after the calibration procedure has been completed. The value of heading offset is specific to the heading sensor that is connected at the time the offset is entered.
1. Activate the Heading Offset by pressing and holding the button for 2 seconds. The reading starts flashing.
2. Increase the compass reading using the button or decrease the compass reading using the button.
3. Save the offset by pressing and holding the button.

IS15 General Manual
Send
Displays ‘-Tx’ if the particular instrument is sending the particular message on Roblink. Only the instrument receiving data from NMEA and sending it to the Roblink displays ‘-Tx’.
Actions to Roblink test results:
1. Zero (0) reading means ‘no message available’.
2. If the numbers are continuously flickering or counting down, perform a Communication Reset on the system.
3. Make sure the recommended cable length or number of
instruments in the system are not exceeded. See Figure 6-6.
4. Check all NMEA connections.
5. Check the output rate of the NMEA ‘talkers’ connected to
IS15. The rate should not be slower than 0.7 Hz.
Note ! A Personal Computer (PC) does not comply with the NMEA hardware specifications. Always use a proper interface between the PC and the IS15 NMEA ports to avoid possible anomalies in the IS15 performance.
Maintenance
9 MAINTENANCE
9.1 General Maintenance
Caution !
Do not use any abrasives, chemical cleaners, petrol or diesel to clean the units.
The instrument heads will require no maintenance apart from occasional cleaning. Use fresh water and a mild soap solution
(not a detergent).
9.2 Annual Maintenance
Check all connections to the instruments and, if necessary, cover with silicone grease or petroleum jelly.
The wind transducer is a robust unit that should give you years of reliable service. However, it will benefit from an application of silicone grease to the connector at the beginning of each season. It is also recommended that the wand is removed over
Winter if the boat is not in use. To prevent corrosion of the connector, always fit the protective cap to the socket when the wand has been removed.
Note ! A broken or lost wind vane can only be replaced by a recalibrated unit from the factory.
A broken anemometer cup may be replaced by the dealer/owner.
9.3 Removal of Instruments
1. If rear access is possible unplug the Roblink connectors from the back of the instrument.
2. Remove the four front panel corners and the fixing screws.
3. Pull the instrument free from the panel, being careful not to strain the cables if they have not yet been disconnected.
Unplug the Roblink connectors from the back, and make up the cables if necessary.

IS15 General Manual
9.4 Return for Service
Please ensure that an instrument that is believed to be faulty is correctly installed, the cabling is in good condition and correct, that all connections are secure, and that a correct supply is present at the Roblink/power connector.
Should the unit have to be returned to your dealer, adequate packing must be used. Please ensure that your name, telephone number, return address, a clear fault description, and if possible a copy of the proof of purchase are included with any returned equipment. Simrad and their representatives are not responsible for any equipment lost in transit.
Please quote the instrument’s serial number in all correspondence. This is found on the back of the instrument.
9.5 Local Master Reset
When an instrument is leaving the factory a Master Reset has been made. However, if an instrument is being used in a different system or setup, you can perform a local Master Reset on the instrument in that system before you disconnect it and move it to a system where you want to put it.
Refer to screen 4 on page 93 or screen 6 on page 104.
1. Turn off the Roblink as per instructions
2. Perform a Master Reset as per instructions
3. Turn on the Roblink as per instructions
You can now install the instrument in another system without having to make a system wide Master Reset and loose the existing calibration and settings in that system.
