[. . . ] Introduction Our Thanks to You and Customer Assistance · Our Thanks to You Thank you for purchasing a CobraMarine® VHF/GMRS Dual Band radio. Properly used, this Cobra® product will give you many years of reliable service. Owner's Manual How Your CobraMarine VHF/GMRS Radio Works This dual band radio is a battery-powered portable transceiver for use afloat or on land. In Marine VHF mode it gives you two-way vessel-to-vessel and vessel-toshore station communications, primarily for safety and secondarily for navigation and operational purposes. In GMRS mode it allows you to reach other GMRS capable radios for short-distance two-way land mobile communication. [. . . ] "Press" means a momentary press of approximately one (1) second. "Press and Hold" means to hold the button down for approximately three (3) seconds. Whenever you press any button except the Talk button on your radio, a brief tone (beep) will sound to confirm the button press. With all button presses, the appropriate icon will appear on the LCD and the backlight will turn On. The backlight will stay on for 10 seconds after the button is released. Two (2) beeps will sound to confirm your setting changes and three (3) beeps will sound to notify you of an error. Common Radio Functions (All Bands) On/Off Volume Control (Clockwise) The following procedures define common operating functions of the radio when in either Marine Standby, GMRS Standby or Weather (WX) Standby modes. Power/Volume/Squelch Controls Power On/Off Control The On/Off/Volume control is located at the upper right side of the radio. Turning the On/Off/Volume control past the detent position will turn the radio On or Off. Volume Control Volume is controlled by turning the On/Off/Volume control. I To decrease the volume, turn the On/Off/Volume control counterclockwise. On/Off Volume Control (Counterclockwise) 38 English Nothing Comes Close to a Cobra® 39 Operating Your Radio Introduction Getting Started Squelch Control Squelch is controlled by turning the lower rotary concentric knob located directly below the On/Off/Volume control. With the power On, turn the knob counterclockwise until you hear a hissing sound, then turn the knob clockwise until the hissing stops. By turning the knob further in a clockwise direction, you will filter weak and mediumstrength signals. By turning the knob in a counterclockwise direction (further from your baseline setting), you will receive weaker signals. Squelch control filters weak signals and radio frequency (RF) noise so that you will clearly hear the signals you want. NOTE If the Squelch control is set so that you can hear a continuous hissing sound, the Memory Scan, TriWatch Scan, CTCSS Scan and DCS Scan functions will be blocked. Radio Speaker and Microphone The internal Radio Speaker and Microphone are located on the bottom front face of the radio below the lower control buttons. An optional Speaker/Microphone port is located at the top of the radio between the antenna and the Power/Volume/ Squelch control. Unthread the Speaker/Microphone port cover to access and install an optional speaker or microphone into this port.
