7InstallationCaution: The OCEANUS will only operate with nominal 12 voltnegative ground battery systems.It is important to carefully determine the most suitable location for yourOCEANUS on your vessel. Electrical, mechanical, and environmentalconsiderations must all be taken into account. You should select theoptimum relationship among these considerations.Keep in mind the flexibility designed into the OCEANUS so thatyou can most conveniently use your radio. Features which should beconsidered are:1. The universal mounting bracket may be installed on either the topor bottom of a shelf, on a bulkhead, or for overhead mounting.2. The REMOTE speaker jack can be used with an auxiliaryspeaker.3. All connections are “plug-in” type for easy removal of the radio.4. Front fire internal speaker allows convenient in-dash mountingusing the optional bracket.Choosing a LocationSome important factors to consider in selecting the location for yourOCEANUS:1. Select a location that is free from spray and splash.2. Keep the battery leads as short as possible. Direct connection tothe battery is most desirable. If direct connection cannot be madewith the supplied power lead, any extension should be made with#10 AWG wire. Long extensions should use larger gauge wire.3. Keep the antenna lead as short as possible. Long antenna leadscan cause substantial loss of performance for both receiving andtransmitting.4. Locate your antenna as high as possible and clear from metalobjects. The reliable range of coverage is a direct function of theantenna height.5. Select a location that does not allow the radio to be subjected todirect sunlight (including that coming through windows).6. Select a location that allows free air flow around the heat sink onthe rear of the radio.7. Select a location well away from the ship’s compass. Auxiliaryspeakers also should be located away from the compass.
