Installation  
EMC installation guidelines  
All Raymarine equipment and accessories are designed to the best industry  
standards for use in the recreational marine environment.  
Raymarine specified cables are used. Cutting and rejoining these  
cables can compromise EMC performance and must be avoided unless  
doing so is detailed in the installation manual/  
Their design and manufacture conforms to the appropriate Electromagnetic  
Compatibility (EMC) standards, but correct installation is required to  
ensure that performance is not compromised. Although every effort has  
been taken to ensure that they will perform under all conditions, it is  
important to understand what facts could affect the operation of the  
product.  
Suppression ferrite  
If a suppression ferrite is attached to a cable, this  
ferrite should not be removed. If the ferrite needs to  
be removed during installation it must be reassem-  
bled in the same position.  
D8852_1  
The guidelines here describe the conditions for optimum EMC performance,  
but it is recognized that it may not be possible to meet all of these condi-  
tions in all situations. To ensure the best possible conditions for EMC  
performance within the constraints imposed by any location, always ensure  
the maximum separation possible between different items of electrical  
equipment.  
The illustration shows typical cable suppression  
ferrites used with Raymarine equipment. Always  
use the ferrites supplied by Raymarine.  
Connections to other equipment  
If your Raymarine equipment is to be connected to other equipment using a  
cable not supplied by Raymarine, a suppression ferrite MUST always be  
attached to the cable near to the Raymarine unit.  
For optimum EMC performance, it is recommended wherever possible:  
Raymarine equipment and cables connected to it are:  
At least 3 ft. (1m) from any other equipment transmitting or  
carrying radio signals. In the case of Single Side Band (SSB) radio,  
the distance should be increased to 7 ft. (2m).  
More than 7 ft. (2m) from the path of a radar beam. A radar beam  
can normally be assumed to spread 20 degrees above and below  
the radiating element.  
The equipment is supplied from a separate battery to that used for  
engine start. Voltage drops below 10 V, and starter motor transients,  
can cause the equipment to reset. This will not damage the equipment,  
but may cause the loss of some information and may change the oper-  
ating mode.

Inter-unit cables  
The inter-unit cable, illustrated below, is fitted with an 8-way plug and  
power cores (covered with a clear protective sleeve) for connecting to the  
scanner.  
Cable requirements  
You need to consider the following points before installing the system  
cables:  
You need to connect the scanner to the display unit and power. The  
cable required will depend on the display unit and scanner type.  
All cables should be adequately clamped and protected from physical  
damage and exposure to heat - avoid running cables through bilges or  
doorways, or close to moving or hot objects.  
To display or extension  
To Radome Scanner  
Acute bends must be avoided.  
Where a cable passes through an exposed bulkhead or deckhead, a  
watertight gland or swan neck tube should be used.  
(power supplied via display unit)  
The length of the cable supplied should be sufficient to complete the cable  
run on most small boats. For longer runs, additional or replacement cables  
are available. These cables have four power cores to minimize voltage  
drops over the longer cable run.  
Avoid cutting and rejoining cables. If this cannot be avoided refer to  
Extending the power cable on page -11.  
Scanner cables  
Optional cable lengths available are:  
A radome scanner connected to a C or E-Series display receives power via  
the display unit.  
Part No. M92668 - 15 m heavy extension cable.  
Part No. M92669 - 25 m heavy replacement cable.  
The maximum inter-unit cable length is limited by the minimum supply  
voltage, the scanner type (18” or 24 “radome), and the cable type (2 or 4  
power cores).  
Running the cable to the scanner  
DO NOT pull the cable through bulkheads using a cord  
attached to the connector. This could damage the  
connections.  
The cable entrance is at the rear of the scanner unit. If the unit is mounted  
on a hollow mast, the cable may be run inside the mast and fed though the  
unit’s cable entrance. Make sure that the cable does not chafe where it  
enters and exits the mast.  
For boats with 12 V DC power systems details of recommended cable(s) for  
different run lengths can be found in Extending the power cable on  
page -11.  
Boats with 24 V DC power systems can use any combination of inter-unit  
cables.  
To minimize electrical interference try to avoid running radar cables near  
other on board electrical equipment. It is also good practice to avoid  
running radar cables in parallel with power cables.  
 
10  
Radome Scanners - Users Guide  
Radome scanners receive power from the display via the inter-unit cable.  
The display power cable is supplied with the display unit and details for  
connecting power are detailed in the relevant Owner’s handbook.  
Power cables  
Radome radar systems are intended for use on boat’s DC power systems  
operating in the range 10.7 to 32 V DC. That is 12 V and 24 V systems, they  
should not be used on 32 V systems.  
Grounding the radar system  
It is important that an effective radio frequency (RF) ground is connected to  
the radar system.  
A 1.5 m (5ft) power cable is supplied with the display unit for connecting  
the boat’s DC power to the radar scanner via the display unit.Refer to the  
relevant display unit handbook for details on connecting this cable.  
You must ground the radar by connecting the drain wire (screen) of the  
power cable to the nearest ground point of your boat’s RF ground system.  
Full details can be found in the Owner’s Handbook for your display unit.  
Extending the power cable  
24 V power systems  
If your boat has a 24 V power system, the power cable may be extended by  
up to 20 m using a wire gauge of 1.5 mm (AWG 16) or greater, irrespec-  
tive of the inter-unit cable length.  
If you need to extend the wire, the extension wire should be an 8 mm braid  
or 6 mm (AWG 10) multi-strand cable.  
2
2
If your boat does not have an RF system, connect the drain wire to the  
negative battery terminal.  
12 V power systems  
If your boat has a 12 V power system, longer power cable runs may require  
larger wire gauges to minimize any voltage drop in the cable.  
For full details on extending the power cable and maximum permissible  
lengths refer to Extending the power cable on page -11.  
Power requirements  
This radar is not recommended for use on ‘positive’ ground  
boats. The power cable earth screen must be connected to  
the boat’s ground.  
The boat’s power system should be either:  
Negative grounded, with the negative battery terminal connected to  
the boat’s ground, or,  
Floating with neither battery terminal connected to the boat’s ground.

Set up, alignment and timing checks  
Switch on and initial set up  
1. Press and hold the POWER key of the display unit until the unit beeps.  
The magnetron warm-up sequence should start, after which the unit  
should enter standby mode.  
2. If necessary, adjust the lighting and contrast.  
3. If necessary, change the default language settings.  
Transmission check  
Ensure that all personnel are clear of the scanner and switch to transmit  
mode. Run through the radar operations as described in the relevant  
display unit’s Owner’s Handbook and check that all the expected data is  
displayed.  
Bearing alignment  
With the system correctly installed, check the bearing alignment to ensure  
that targets appear at their correct bearing relative to the boat’s bow.  
Adjust the alignment as necessary.  
Display timing adjustment  
The display timing can be affected by the length of cable used to connect  
the scanner to the display unit. This in turn affects the short range accuracy  
shown on the display.  
It is advisable to check the display timing before using the system for  
navigation.
