Installation  
Caution: The OCEANUS will only operate with nominal 12 volt  
negative ground battery systems.  
It is important to carefully determine the most suitable location for your  
OCEANUS on your vessel. Electrical, mechanical, and environmental  
considerations must all be taken into account. You should select the  
optimum relationship among these considerations.  
Keep in mind the flexibility designed into the OCEANUS so that  
you can most conveniently use your radio. Features which should be  
considered are:  
1.  
The universal mounting bracket may be installed on either the top  
or bottom of a shelf, on a bulkhead, or for overhead mounting.  
2.  
The REMOTE speaker jack can be used with an auxiliary  
speaker.  
3.  
4.  
All connections are “plug-in” type for easy removal of the radio.  
Front fire internal speaker allows convenient in-dash mounting  
using the optional bracket.  
Choosing a Location  
Some important factors to consider in selecting the location for your  
OCEANUS:  
1.  
2.  
Select a location that is free from spray and splash.  
Keep the battery leads as short as possible. Direct connection to  
the battery is most desirable. If direct connection cannot be made  
with the supplied power lead, any extension should be made with  
#10 AWG wire. Long extensions should use larger gauge wire.  
3.  
4.  
Keep the antenna lead as short as possible. Long antenna leads  
can cause substantial loss of performance for both receiving and  
transmitting.  
Locate your antenna as high as possible and clear from metal  
objects. The reliable range of coverage is a direct function of the  
antenna height.  
5.  
6.  
7.  
Select a location that does not allow the radio to be subjected to  
direct sunlight (including that coming through windows).  
Select a location that allows free air flow around the heat sink on  
the rear of the radio.  
Select a location well away from the ship’s compass. Auxiliary  
speakers also should be located away from the compass.  
7
 
Engine Noise Suppression  
Interference from the impulse noise generated by the electrical systems  
of engines is sometimes a problem with radios. The OCEANUS has  
been designed to be essentially impervious to ignition impulse noise and  
alternator noise. However, in some installations it may be necessary to  
take measures to further reduce the effect of noise interference. All DC  
battery wires, antenna lead, and accessory cables should be routed  
away from the engine and engine compartment, and from power cabling  
carrying high currents.  
In severe cases of impulse noise interference, it may be necessary to  
install a noise suppression kit. Contact your Uniden Dealer for more  
information.  
Antenna Considerations  
A variety of antennas are available from a number of quality suppliers. It  
is recommended you draw upon the advice of your Uniden Dealer in  
determining a suitable antenna for your vessel and range requirements.  
In general, communication range is increased by using a high-gain  
antenna placed as high as possible above the water line. Antennas  
should be located away from metal objects. Antennas should not have  
excessively long coaxial feed cables.  
8
 
Installing the OCEANUS  
After you have carefully considered the various factors affecting your  
choice of location, position the radio (with the bracket, microphone,  
power cord, antenna and any auxiliary cables installed) into the selected  
location to assure there is no interference with the surrounding items.  
Mark the location of the mounting bracket. Remove the bracket from the  
radio and use it as a template to mark the holes to be drilled for the  
mounting hardware. Drill the holes and mount the bracket with hardware  
compatible with the material of the mounting surface.  
Note:  
This HEXAGON HEAD BOLT is  
only for mounting the bracket  
with hardware. Do not use it for  
installing the radio in the  
mounting bracket.  
Connect the red wire of the supplied power cord to the positive (+)  
battery supply. Connect the black wire of the power cord to ground. The  
power cord is equipped with a fuse to protect the radio. Use only a Six  
(6) Ampere fast blow fuse for replacement. Connect the power cord to  
the keyed connector on the power “pigtail”.  
Connect the antenna and all other auxiliary cables and accessories.  
Install the radio in the mounting bracket and connect all cables and  
accessories to the appropriate jacks and connectors.  
Note:  
Do not use any other mounting  
knobs than the ones enclosed.  
Do not insert the knobs without  
attaching the bracket.

Care and Maintenance  
Your OCEANUS is a precision piece of electronic equipment and you  
should treat it accordingly. Due to the rugged design, very little  
maintenance is required. However, a few precautions should be  
observed:  
• If your radio has been accidentally subjected to spray or splash,  
you should immediately wipe it down with a soft cloth dampened  
with fresh water.  
• If the antenna has been damaged, you should not transmit  
except in the case of an emergency. A defective antenna may  
cause damage to your radio.  
You are responsible for the continued FCC technical compliance  
of your radio.  
You are urged to arrange for periodic performance checks with  
your Uniden Marine Dealer.
