excessiveexposuretowatersplashesorcontinuousrain.
• Selectalocationthatwon’texposeyourradioto
continuousdirectsunlightwhichcouldcauseoverheating
orUVdegradation.
• Ensurethatthelocationallowsafreeowofairaround
theheatsinkonthebackoftheradio.
• Themicrophoneandallcontrolsshouldbereadily
