Uniden_MC-6700_Manual操作说明书手册

INSTALLATIONCAUTION:The MC6700 will operate with a nominal 12 volt negative positiveground battery system,but read carefully the Item 6 of the paragraph of ACTUAL INSTALLATION mentioned below.CHOOSING A LOCATION1.Select a location that is free from spray and splash2.Select a location that minimizes exposure to direct sunlight (including that com-ing through windows).3.Select a location that allows free air flow around the heat sink on the rear of theradio.4.Select a location well away from the ship's compass.Auxiliary speakers alsoshould be located away from the compass.5.Select a location as close to the battery as possible (in order to keep battery leadsas short as possible).Direct connection to the battery is most desirable.If directconnection cannot be made with the supplied power lead.any extension shouldbe made with at least 5.5mm"wire.electronics.ENGINE NOISE SUPPRESSIONInterference from the impulse noise generated by the electrical systems of engines issometimes a problem with radios.The MC6700 has been designed to be immune toignition impulse noise and alterator noise.However,in some installations it may benecessary to take measures to further reduce the effect of noise interference.All DCbattery wires.antenna leads and accessory cables should be routed away from theengine and engine compartments and from power cabling carrying particularly highcurrents.ANTENNA CONSIDERATIONS1.Keep the antenna lead as short as possible.Long antenna leads can cause substan.tial loss of performance for both receiving and transmitting.2.Locate your antenna as high as possible and clear from metal objects.The reliablerange of coverage is direct function of antenna height.The general rules forantennas are:The more gain the greater the range and,the higher above the waterline the greater the ranger.MOUNTING CONSIDERATIONSKeep in mind the flexibility designed into the MC6700 so that you can mostconveniently use your radio.The points which should be considered are:1.Universal mounting bracket may be installed on either top or bottom for shelfbulkhead,or overhead mounting.2.The microphone connector faces forward allowing convenient in-dash or "built.in”installations.=2-
