Important Safety Information Before installing and using your CobraMarine VHF radio, please read these general precautions and warnings.To make the most of this radio, it must be installed and used properly. Please read the installation and operating instructions carefully before installing and using it. Special attention must be paid to the WARNING and NOTICE statements in this manual.WARNING Statements identify conditions that could result in personal injury or loss of life.NOTICE Statements identify conditions that could cause damage to the radio or other equipment.This CobraMarine radio is designed for and classified as “Occupational Use Only.” It must only be used in the course of employment by individuals aware of both the hazards and the ways to minimize those hazards. This radio is NOT intended for use in an uncontrolled environment by the “General Population.”Q FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields.Q American National Standards Institute (C95.1-1992), IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.Q American National Standards Institute (C95.3-1992), IEEE Recommended Practice for the Measurement of Potentially Hazardous Electromagnetic Fields — RF and Microwave.Q Cobra Electronics Corporation™ recommendations for radio frequency exposure are based upon the federal regulatory requirements in the U.S.A. Your country may have different requirements. Ask your dealer or another knowledgeable person. Compliance with recommendations for Radio Frequency Exposure is the responsibility of both the antenna installer and the radio operator.The following WARNINGS and NOTICES will make you aware of RF exposure hazards and how to assure you operate the radio within the FCC RF exposure limits established for it.WARNINGS Your radio generates electromagnetic RF (radio frequency) energy when it is transmitting. To ensure that you and those around you are not exposed to excessive amounts of that energy, DO NOT touch the antenna when transmitting. KEEP the radio at least two (2) inches (5 cm) away from yourself and others when transmitting. SEE page 20 in the antenna requirements section for further information.DO NOT operate the radio without a proper antenna or equivalent dummy load attached. Doing so may expose you to excessive RF energy and will damage the radio.DO NOT transmit more than 50% of the time the radio is in use — 50% duty cycle. The radio is transmitting when the Talk button is pressed and the transmit information shows on the LCD screen.ALWAYS use only Cobra authorized accessories.NEVER connect the transceiver to AC power. It can be a fire hazard, may cause an electric shock, and may damage the transceiver.NEVER mount the transceiver or microphone where they might interfere with operation of your vessel or cause injury.DO NOT allow children or anyone unfamiliar with proper procedures to operate the radio without supervision.Failure to observe any of these warnings may cause you to exceed FCC, Industry Canada or EU RF exposure limits or create other dangerous conditions.NOTEThroughout this manual, the term “Transceiver” will be used to identify the main unit containing the LCD screen and controls. The term “Radio” will be used to identify the entire equipment including transceiver, microphone, antenna and any attached external speakers.
NOTICESAVOID using or storing the radio at temperatures below -4°F (-20°C) or above 140°F (55°C).NEVER connect the transceiver to DC power greater than 16 volts or to any DC source with reversed polarity. Doing so will damage the transceiver.DO NOT cut the power cables attached to the transceiver. Improper reconnection with reversed polarity will damage the transceiver.POSITION your radio, external speakers, and cables at least three (3) feet (0.9 m) away from your vessel’s magnetic navigation compass. CHECK your compass before and after installation to be sure that it has not introduced any deviation.DO NOT attempt to service any internal parts yourself. Have any necessary service performed by a qualified technician.DO NOT drop the transceiver or microphone. Doing so may crack the case or damage a waterproof seal. Once these items have been dropped, the original waterproofing cannot be guaranteed.DO NOT use chemicals or solvents such as mineral spirits and alcohol to clean your radio. They may damage the case surfaces.Changes or modifications to your radio MAY VOID its compliance with FCC (Federal Communications Commission) rules and make it illegal to use.Recommendations For Marine Communication The frequencies your radio uses are set aside to enhance safety afloat and for vessel navigation and operational messages over a range suitable for nearshore voyages. If the 25 watt maximum output of your radio isn’t sufficient for the distances you travel from the coast, consider installing more powerful radio equipment such as HF single side band or satellite radio for your vessel.The U.S. Coast Guard does not endorse cellular telephones as substitutes for marine radios. They generally cannot communicate with rescue vessels and, if you make a distress call on a cellular telephone, only the party you call will be able to hear you. Additionally, cellular telephones may have limited coverage over water and can be hard to locate. If you don’t know where you are, the Coast Guard will have difficulty finding you if you’re using a cellular telephone.However, cellular telephones can have a place on board where cellular coverage is available — to allow social conversations and keep the marine frequencies uncluttered and available for their intended uses.Sea Tow Automated Radio Check (ARC) System Please try the Sea Tow Automated Radio Check service. Areas where the safety check service is available include the East Coast, Gulf of Mexico, Southern California, and select inland locations including the Great Lakes. The first and only boating safety program of its kind, the Sea Tow Automated Radio Check service is fully automated and allows 24 hour a day automated responses to radio check calls.Conducting a radio check through the Sea Tow Automated Radio Check service couldn’t be simpler. All boaters need to do is tune their VHF radio to Channel 24, 25, 26, 27, 28 or 84 (channel varies by location), then key the mic and ask for a radio check. The system responds to each radio check with an automated reply including the location, and also replays the boater’s original radio transmission, allowing them to assess the strength of the signal and confirm the VHF radio is in good working order.To find the Sea Tow Automated Radio Check service channel in an area boaters, radio owners should visit www.seatow.com/arc. The web page allows you to search for the local channel and has an instructional video on how to use the service step by step.FCC LICENSING INFORMATION CobraMarine VHF radios comply with the FCC (Federal Communication Commission) requirements that regulate the Maritime Radio Service.This CobraMarine radio incorporates a VHF FM transceiver designed for use in the frequency range of 156.025 to 163.275 MHz. It requires 13.8 volts DC and has a switchable RF output power of one (1) or 25 watts.The transceiver is capable of Class-D (Digital Selective Calling) operation in accordance with CFR Part 47, Section 80,225.The radio operates on all currently allocated marine channels and is switchable for use according to U.S.A., International, or Canadian regulations. It features instant access to emergency Channel 16 and calling Channel 9 as well as NOAA (National Oceanic and Atmospheric Administration) All Hazards Radio with Alert that can be accessed by pressing one (1) key.An FCC ship station license is no longer required for any vessel traveling in U.S.A. waters which uses a VHF marine radio, RADAR, or EPIRB (Emergency Position Indicating Radio Beacon), and which is not required to carry radio equipment. However, any vessel required to carry a marine radio on an international voyage, carrying a HF single side band radiotelephone, or carrying a marine satellite terminal must obtain a station license.FCC license forms and applications for ship and land stations can be downloaded through the Internet at www.fcc.gov/forms. Forms can also be obtained by calling the FCC at 888-225-5322.If your vessel will be entering the sovereign waters of a country other than the U.S.A. or Canada, you should contact that country’s communications regulatory authority for licensing information.
Currently, the FCC does not require recreational boaters to have a license. The United States Coast Guard recommends that the boat’s registration number and state of registry (e.g., IL 1234 AB) be used as a call sign and be clearly visible on the vessel.You need a Radio Operator’s Certificate if your vessel is operated in Canadian waters. Radio Operator training and certification is available from the Canadian Power Squadron. Visit their website (http://www.cps-ecp.ca/english/newradiocard.html), contact the nearest field office or write: Industry of Canada, Radio Regulatory Branch, Attn: DOSP, 300 Slater Street, Ottawa, Ontario, Canada K1A 0C8.All users are responsible for observing domestic and foreign government regulations and are subject to severe penalties for violations. The VHF frequencies on your radio are reserved for marine use and require a special license to operate from land, including when your boat is on its trailer.NOTE This device complies with part 15 of the FCC Rules. Operation is subject to the following two (2) conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation.FCC Warnings: Replacement or substitution of transistors, regular diodes, or other parts of a unique nature, with parts other than those recommended by Cobra® may cause a violation of the technical regulations of part 80 of the FCC Rules, or violation of type acceptance requirements of part 2 of the rules.VHF Marine Radio Procedures Whenever your boat is underway, the radio must be turned On and be tuned to Channel 16, except when being used for messages.Try 1 watt first if the station being called is within a few miles. Try a second call after waiting two (2) minutes. If there is no answer, switch to a higher power. This will conserve your battery and minimize interference to other users by avoiding repeated calls.Call a coast station on its assigned channel. You may use Channel 16 when you do not know the assigned channel.Call other vessels on Channel 16 or on Channel 9. (Channel 9 is preferred for recreational vessel use.) You may also call on ship-to-ship channels when you know that the vessel is listening on a ship-to-ship channel.The use of Channel 16 is permitted for making initial contact (hailing) with another vessel. The limits on calling must be followed. Be reminded, Channel 16’s most important function is for Emergency Messages. If, for some reason, Channel 16 is congested, the use of Channel 9, especially in U.S. waters, may be used as the initial contact (hailing) channel for non-emergency communication.You must not call the same station for more than 30 seconds at a time. If you do not get a reply, wait at least two (2) minutes before calling again. After three (3) calling periods, wait at least 15 minutes before calling again.After contacting another station on a calling channel, change immediately to a channel which is available for the type of message you want to send.Identify, in English, your station by your FCC call sign, ship name, the state registration number, or other official number at both the beginning and end of each message.You MUST NOT transmit: Q False distress or emergency messages. Q Messages containing obscene, indecent, or profane words or meaning. Q General calls, signals, or messages (messages not addressed to a particular station) on Channel 16, except in an emergency or if you are testing your radio. Q When you are on land. Voice Calling To Call Another Vessel Or A Shore Installation Such As A Lock Or Bridge Tender: Q Make sure your radio is On. Q Select Channel 16 and listen to make sure it is not being used. NOTE Channel 9 may be used by recreational vessels for general-purpose calling. This frequency should be used whenever possible to relieve congestion on Channel 16. Q When the channel is quiet, press the Talk button and call the ship you wish to call. (Hold the microphone a few inches from your face and speak directly into it in a normal tone of voice — clearly and distinctly.) Say “[name of station being called] THIS IS [your vessel’s name or call sign].” Q Once contact is made on the calling channel, you must switch to a proper working channel. See the channel listing on page 66 through 78.The vessel Corsair calling the vessel Vagabond:
Corsair: “Vagabond, this is Corsair (station license number call sign).” Vagabond: “Corsair, this is Vagabond. Over.” Corsair: “Vagabond go to working Channel 68. Over.” Both parties switch over to the agreed upon working channel.... Corsair: “Vagabond I need to talk to you about... Over.” Vagabond: “Corsair in answer to your question about... Over.” Corsair: “Vagabond, thanks for the information about... (call sign and out).” After each transmission, say “OVER” and release the microphone Push to Talk (PTT) button. This confirms that the transmission has ended. When all communication with the other vessel is totally completed, end the message by stating your call sign and the word “OUT.” Remember, it is not necessary to state your call sign with each transmission, only at the beginning and end of the message.NOTE For best sound quality at the shore station or other vessel receiving your call, hold the microphone/speaker at least 2 in. (51 mm) from your mouth and slightly off to one (1) side. Speak in a normal tone of voice.Digital Selective Calling (DSC) Digital selective calling is a semi-automated system for establishing a radio call. It has been designed by the International Maritime Organization (IMO) as an international standard for VHF, MF, and HF calls and is part of the Global Maritime Distress and Safety System (GMDSS). DSC will eventually replace aural (listening) watches on distress frequencies and will be used to announce routine and urgent maritime safety information broadcasts. Until DSC is fully implemented, it is still necessary to maintain a listening watch on Channel 16.The DSC system allows mariners to instantly send a distress call with GPS position coordinates (requires a GPS receiver to be connected to the radio) to the Coast Guard and other vessels within range of the transmission. DSC also allows mariners to initiate and receive distress, urgent, safety, routine, position request, position send, and group calls between vessels equipped with DSC capable radios.Maritime Mobile Service Identity (MMSI) The MMSI Number Is Available In The U.S.A. From Any Of Two (2) Sources: Q U.S. Power Squadron www.usps.org Q BoatU.S.: 1-800-563-1536 – www.boatus.com/mmsiNOTE The above references are for recreational vessels only. Commercial vessels should contact the FCC.An MMSI is a nine (9) digit number used on a marine radio capable of using digital selective calling (DSC). It is used to selectively call other vessels or shore stations and is similar to a telephone number.For your CobraMarine™ radio to operate in the DSC mode, you must enter your maritime mobile service identity (MMSI) number. See page 41 for instructions on how to enter it. In Canada, Contact: Q Industry Canada Spectrum Management Office (only available on the Internet): www.ic.gc.ca and search for “MMSI”.To Obtain An MMSI Number Outside The U.S.A.:Users can obtain an MMSI from their country’s telecommunications authority or ship registry. This may involve amending or obtaining a ship station license.WARNING This equipment is designed to generate a digital maritime distress and safety signal to facilitate search and rescue. To be effective as a safety device, this equipment must be used only within communication range of a shore-based VHF marine channel to distress and safety watch system. The range of the signal may vary, but under normal conditions should be approximately 20 nautical miles.
Emergency Messages And Distress Procedure The ability to summon assistance in an emergency is the primary reason to have a VHF marine radio. The marine environment can be unforgiving, and what may initially be a minor problem can rapidly develop into a situation beyond your control.The Coast Guard monitors Channel 16, responds to all distress calls, and coordinates all search and rescue efforts. Depending on the availability of other capable vessels or commercial assistance operators in your vicinity, Coast Guard or Coast Guard Auxiliary craft may be dispatched.In any event, do communicate with the Coast Guard as soon as you experience difficulties and before your situation becomes an emergency. Use the emergency message procedures only after your situation has become grave or you are faced with a sudden danger threatening life or property and requiring immediate help. Use channel 16 to communicate your emergency message. Make sure you transmit on high power. If you are merely out of gas, do not send an emergency message. Drop your anchor and call a friend or marine to bring the fuel you need or to give you a tow.The three (3) spoken international emergency signals are:The distress signal MAYDAY is used to indicate that a station is threatened by grave and imminent danger and requests immediate assistance.The urgency signal PAN is used when the safety of the vessel or person is in jeopardy. (This signal is properly pronounced pahn.)The safety signal SECURITE is used for messages about the safety of navigation or important weather warnings. (This signal is properly pronounced see-cure-it-tay.)When using an international emergency signal, the appropriate signal is to be spoken three (3) times prior to the message.You must give any message beginning with one (1) of these signals priority over any other messages. ALL stations MUST remain silent on Channel 16 for the duration of the emergency unless the message relates directly to the emergency.If you hear a distress message from a vessel, stand by your radio. If it is not answered, YOU should answer. If the distressed vessel is not nearby, wait a short time for others who may be closer to acknowledge. Even if you cannot render direct assistance, you may be in a position to relay the message.
Speak slowly — clearly — calmly.1. Make sure your radio is On.2. Select VHF Channel 16.3. Press Talk button and say: “MAYDAY — MAYDAY — MAYDAY.” (Or “PAN — PAN — PAN,” or “SECURITE — SECURITE — SECURITE.”)4. Say: “THIS IS [your vessel name or call sign].”5. Say: “MAYDAY (or “PAN” or “SECURITE”) [your vessel name or call sign].6. Tell where you are: (what navigational aids or landmarks are near).7. State the nature of your distress.8. State the kind of assistance needed.9. Give number of persons aboard and conditions of any injured.10. Estimate present seaworthiness of your vessel.11. Briefly describe your vessel (length, type, color, hull).12. Say: “I WILL BE LISTENING ON CHANNEL 16.”13. End message by saying: “THIS IS [your vessel name or call sign] OVER.”14. Release Talk button and listen. Someone should answer. If not, repeat the call, beginning at item 3 above.Keep the radio nearby. Even after your message has been received, the Coast Guard can find you more quickly if you can transmit a signal for a rescue boat to hone in on.“Mayday — Mayday — Mayday” “This is Corsair — Corsair — Corsair” [or “Illinois 1234 AB” three (3) times] “Mayday Corsair (or Illinois 1234 AB)” “Navy Pier bears 220 degrees magnetic — distance five (5) miles” “Struck submerged object and flooding — need pump and tow” “Four adults, three children aboard — no one injured” “Estimate we will remain afloat one-half (1⁄2) hour” “Corsair (or Illinois 1234 AB) is 26 foot sloop with blue hull and tan deck house” “I will be listening on Channel 16” “This is Corsair (or Illinois 1234 AB)” “Over”It is a good idea to write out a script of the message form and post it where you and others on your vessel can see it when an emergency message needs to be sent.Marine Distress Procedure – DSC Digital Selective Calling (DSC) is a semi-automated system that will allow you to press the Distress button from any routine to make a distress call. When the distress button is pressed, all other channels go to Standby mode and allow the digitally encoded “pre-programmed” message to take precedence. Important information such as your MMSI number, position and name will be transmitted on Channel 16. The distress alarm will sound for two (2) minutes or until the alarm is cleared. The DSC system allows you to choose a “pre-programmed” distress call such as: “Man Overboard, Sinking, Collision.” There are many pre-programmed choices to choose from. If a GPS is connected to your radio, your coordinates will also be sent to the Coast Guard as well as to other vessels that are within range of the transmission. DSC calling also allows the user to initiate and receive distress, urgent, safety, routine, position request, position send and group calls between vessels equipped with DSC capable radios.WARNING This radio will generate a digital maritime distress and safety signal to help facilitate search and rescue. This radio must be used only within communication range of a shore based VHF station with a distress and safety watch system. The range of the signal may vary, however, under normal conditions should be approximately 20 nautical miles.

Antenna Requirements And Attachment Your CobraMarine VHF radio requires an external marine antenna to send signals into the air and to receive them. The radio is arranged to use any of the popular marine VHF antennas, but it is up to you to choose which antenna to use.Since it represents the link between your radio and the outside world, Cobra® suggests you purchase the best quality antenna, coaxial cable, and connectors you can. This is best accomplished with the advice and guidance of a knowledgeable dealer who can assess the variables involved with your particular boat and preferences.WARNING Compliance with FCC requirements for Radio Frequency Exposure is the responsibility of both the antenna installer and the radio operator.Safe Maximum Permissible Exposure (MPE) Radius To avoid health hazards from excessive exposure to RF energy, FCC OET Bulletin 65 establishes an MPE radius of 10’ (3 m) for the maximum power of your radio with an antenna having a maximum power gain of 9 dBi. This means that all persons must be at least 10’ (3 m) away from the antenna when the radio is transmitting.Installation Requirements A) An omnidirectional antenna with a gain not greater than 9 dBi must be mounted at least 16.4’ (5 m) above the highest deck where people may be during radio transmissions, measured vertically from the lowest point of the antenna. This provides the minimum separation distance to comply with RF exposure requirements and is based on the MPE radius of 10’ (3 m) plus the 6.6’ (2 m) height of an adult.B) For vessels without structure to mount the antenna as described in A, it must be mounted as follows AND all persons must be outside the 10’ (3 m) MPE radius during radio transmissions. The antenna must be mounted so that its lowest point is at least 3.3’ (1 m) vertically above the heads of all persons during radio transmissions.Radio Operator Requirements Do not transmit when anyone is within the MPE radius of the antenna unless that person or persons are shielded from the antenna by a grounded metallic barrier. This is especially important on vessels with antennas mounted as described in B where no one may be within 9’ (2.8 m) horizontally from the base of the antenna during transmissions.FAILURE TO OBSERVE THE ABOVE LIMITS MAY EXPOSE THOSE WITHIN THE MPE RADIUS TO RF ENERGY ABSORPTION IN EXCESS OF THE FCC MAXIMUM PERMISSIBLE EXPOSURE. IT IS THE RADIO OPERATOR’S RESPONSIBILITY TO INSURE THAT MPE LIMITS ARE HEEDED AND THAT NO ONE IS WITHIN THE MPE RADIUS DURING TRANSMISSIONS. Once the antenna is installed, the Coaxial Cable Lead can be attached to the socket at the back of the transceiver. CAUTION Attempting to transmit without an antenna attached will damage your CobraMarine VHF radio.
External Devices And Connections Your CobraMarine VHF radio is set up to connect auxiliary devices for navigation, convenience, and added versatility. As is the case with the antenna, choosing these devices is best done with the advice and guidance of a knowledgeable dealer. Standard connectors are provided on the front and back of the transceiver.An External Speaker can provide greater volume to hear messages than the speaker incorporated in the CobraMarine microphone/speaker.To Install An External Speaker:1. Connect the wires to the External Speaker as follows:Orange wire - +Positive connectionBlack wire - -Negative connection (Black wire is common shared -Negative for the External Speaker and PA output)2. Make sure to solder, crimp, or twist the wires together firmly and use shrink tubing or electrical tape to waterproof the connection.At times, it may be handy to hail other boats or give instructions to line handlers on the dock. Your CobraMarine VHF radio can be switched to operate in the Public Address mode through an attached PA speaker.To Install A Public Address Speaker:1. Connect the wires to the External Speaker as follows:Red wire - +Positive connectionBlack wire - -Negative connection (Black wire is common shared -Negative for the External Speaker and PA output)2. Make sure to solder, crimp, or twist the wires together firmly and use shrink tubing or electrical tape to waterproof the connection.Your Cobra Marine radio does not include a built-in GPS receiver. After connecting an external GPS receiver, your position will be continuously indicated on the LCD and, most importantly, it will be included automatically with any DSC Distress message you may need to send. That will take the “search” out of “search and rescue.An external GPS input connector has been provided to allow connection to a back-up GPS receiver.To Install A GPS Device:1. Install the GPS device in a convenient location according to its manufacturer’s directions.2. Plug-in the optional Cobra C.P.S. (Cobra Positioning System) into the provided 2.5mm jack.3. Or using the supplied 2-wire adapter wire as follows: Yellow wire - NMEA 0183 +Data in Green wire - NMEA 0183 -Data in.NOTE Satellite acquisition time is dependent on the antenna mounting location. If the acquisition takes too long, relocate the radio or use an external GPS receiver.NOTE GPS data input is as follows:• Input voltage (peak to peak): 10V• Maximum data rate: 4800 baud• Impedance: 4KΩ
Getting Started Refer to the foldout on the front cover of this manual to identify the various controls and indicators on your radio. Throughout this manual you will be instructed to press or to press and hold buttons on the transceiver. Press means a momentary press, then release; press and hold means to hold the button.When your CobraMarine VHF radio is On, you can expect to hear the following tones and alarms. The volume of these sounds is controlled by the circuitry in the radio and is not affected by the volume set with the On-Off Power/Volume knob.Confirmation ToneSingle high-pitched beep confirms all button presses except the Talk button. It can be turned On or Off. See set-up routines on page 30.Error Tone Three low-pitched beep indicates an invalid button press.DSC Distress Alarm High—low—high—low—high. Pause, then repeat.

Press any button to turn it Off.Weather AlarmMedium-loud, continuous, medium-pitched series of one-half (1⁄2) second beeps spaced one-half (1⁄2) second apart — sounds when weather alert is turned On and NOAA sends a 1050 Hz weather alert tone on the selected weather channel. Press any button to turn it Off. Transceiver power can be turned On or Off by the On-Off Power/Volume knob on the transceiver. To Turn Your Radio On Or Off: 1. Rotate the Off Power/Volume knob clockwise to turn on the transceiver. To turn off the transceiver, rotate the Off Power/Volume counter clockwise until a “click” is heard. When the radio is powered On, the confirmation tone will sound. The radio will return to the settings in effect when it was last powered Off, the LCD will show the corresponding information, and all controls will be operative. The radio will then be in Standby mode. The On-Off Power/Volume knob on the transceiver controls the speaker volume. The volume adjustment applies only to what you hear from the speaker and does not affect the volume of your outgoing messages. That is controlled by the circuitry of your radio. The volume bar graph will be shown to indicate the volume setting. 2 seconds after finishing the volume adjustment, the radio will return to the Standby mode. To Increase The Volume: • Turn the On-Off Power/Volume knob clockwise. To Decrease The Volume: • Turn the On-Off Power/Volume knob counter-clockwise. Squelch control filters weak signals and radio frequency noise so that you can more clearly hear the signals you want. You can think of it as a variable barrier that blocks what you don’t want to hear.
To Squelch Your Radio: 1. With the Squelch knob turned fully counter-clockwise, turn the On-Off/Volume knob clockwise until you hear a hissing (noise) sound. 2. Turn the Squelch knob clockwise until the hissing sound stops. Turning the Squelch knob further clockwise (higher barrier) will filter weak and medium strength signals until only the strongest signal can get through at the highest squelch setting. The Squelch bar graph will be shown to indicate the Squelch setting. 2 seconds after finishing the Squelch adjustment, the radio will return to the Standby mode. To Receive Weaker Signals: 1. Turn the Squelch knob counterclockwise (lower barrier). If the squelch is set so that you can hear a continuous hissing sound, the memory scan and tri-watch functions will be blocked. Standby mode is the usual mode for the radio whenever it is turned On. From Standby Mode, You Can: Q Change your radio’s settings using set-up routines. Q Receive messages on the current channel as well as DSC messages. Q Listen and Receive NOAA alerts if Weather Alert mode is turned On. Q Switch to Transmit mode using the Talk button. While the radio is in Standby mode, the Receive mode is entered whenever a strong enough signal to break squelch is sent to the radio. You will hear the message through whichever speakers are connected to the radio. To Change The Channel You Are Listening To, You Can Choose One Of The Following: a. Press the Up/Down buttons. This will take you to the next higher or lower VHF channel. For rapid advance, press and hold the Up or Down button. b. Press the Channel 16/9 button. This will take you to Channel 16 with one (1) press and to Channel 9 with a second press. Additional presses will toggle between Channels 16 and 9 and the current user selected channel. c.

DSC Set-Up Digital selective calling — DSC — employs digital RF signals which tend to carry further and be less susceptible to distortion from noise and atmospheric conditions than analog ones. The result is greater range and more reliable message delivery per watt of output power.But, that is not the only advantage of DSC equipped radios. Those radios are set up to interface with GPS and to automate many of the operations involved in sending and receiving messages.
