IMPORTANT NOTICE
This device is only an aid to navigation. Its accuracy can be
affected by many factors, including equipment failure or defects,
environmental conditions and improper handling or use.
It is the user’s responsibility to exercise common prudence and
navigational judgement, and this device should not be relied upon
as a substitute for such prudence and judgement.
1. EMC Installation & Service Guidelines
All Raytheon equipment and accessories are designed to the best
industry standards for use in the leisure marine environment.
Their design and manufacture conforms to the appropriate
Electromagnetic Compatibility (EMC) standards, but correct
installation is essential to maintain EMC performance and CE
compliance. Although every effort has been taken to ensure that they
will perform under all conditions, it is important to understand what
factors could affect the operation of the product.
Installation
All Raytheon equipment and cables connected to it should be;
• At least 1m (3ft) from any equipment transmitting or cables carrying
radio signals eg. VHF radios, cables and antennas. In the case of
SSB radios, the distance should be increased to 2m (7ft).
• More than 2m (7ft) from the path of a radar beam.
• The equipment should be supplied from a different battery than the
one used for engine start. Voltage drops below 10.7V in the power
supply to our products can cause the equipment to reset. This will
not damage the equipment, but may cause the loss of some
information and can change the operating mode.
• Genuine Raytheon cables should be used at all times. Cutting and
rejoining these cables can compromise EMC performance and so
should be avoided unless doing so is detailed in the installation
manual.

Check Before Going to Sea
• Always check the installation before going to sea to make sure that it
is not affected by radio transmissions, engine starting etc.
• In some installations, it may not be possible to prevent the
equipment from being affected by external influences. In general
this will not damage the equipment but can lead to it resetting, or
momentarily may result in faulty operation.
Servicing and Safety
• This product contains no user servicable parts.
• Raytheon equipment should be serviced only by authorised
Raytheon service engineers. They will ensure that service
procedures and replacement parts used will not affect performance.
There are no user serviceable parts in any Raytheon product.
• Always report any EMC related problem to your nearest Raytheon
dealer. We will use any such information to improve our quality
standards.

4. Raystar 114 Installation
The Raystar 114 is designed to receive the signals emitted from the
satellites in a direct path. Ideally, the unit should be mounted upright in
a location that is open and clear of any masts, search lights, or other
structures that could block the line-of-sight reception of the antenna
unit. The height of the receiver is not as important as the receiver having
a clear view horizon to horizon for optimum signal reception. In fact,
the lower the unit can be mounted and have a clear view to satellites, the
better. The more stable the internal GPS antenna, the easier it is to track
satellites lower to the horizon.
Installation of the Raystar 114 should only be undertaken by a
competent installer.
D1340-2
The unit should be separated by at least 7ft (2m) from other
communication antennas and should not be mounted in the direct path
of a Radar’s antenna beam.
While planning the location for the unit, consider finding a convenient
pathway for running the interconnecting cable which will connect the
receiver to the GPS display unit or to the rest of an integrated system.

Installation Guide 7
Ideally the cable should be run in a manner so that it can be hidden from
view and, if possible, be in a direct path to the point of connection. It is
important to keep the cable separated from other shipboard cables as
much as possible to prevent interference pick-up.
CAUTION
Care should be taken that the unit is sited to avoid personal injury
caused by falling on the aerial.
Note: Mounting on the mast of a sailboat is not recommended.
Grounding the System
For optimum operation the unit should be connected to the ship’s
ground system. You can ground the unit using one of the following
three methods:
1. A 24 AWG wire can be connected via the screw connection found
in the base of the unit, as shown in the following illustration. A
suitable wire with eyelet is attached to the unit. If this length is
insufficient, use similar wire and connect with the additional eyelet
and screw provided.

2. The cable screen can be connected to ground.
Note: This will require the insulation to be cut back to obtain
access to the screen.
3. A conducting pole mount, which is connected to ground, can be
screwed into the base of the unit.
