E-11Uniden MHS75 Radio Owner’s ManualWeather modeThe NOAA weather channels now cooperate with the FCC to alert you of other hazards besides weather (child abduction alerts, nuclear, biological, etc.). In weather mode, the radio monitors one of the ten NOAA weather channels. If any type of alert is received, the radio sounds an alert tone and the display blinks. Using the radio in weather modeYou cannot transmit while in weather mode.To enter weather mode, press the  WX-Alert button. To turn off the radio’s alert tone, press any button.To cancel weather mode and return to the previous marine channel, press the WX-Alert button again. Weather mode with Weather Alert WatchBecause weather mode already monitors the weather channels, you don’t need Weather Alert Watch to check the weather channel every seven seconds. If you activate Weather Alert Watch while operating in weather mode, it operates as a type of “sleep mode”: the radio stays on the weather channel and mutes the speaker. If an alert is detected, the radio sounds an alert tone and turns the speaker back on. This mode is very useful when you are anchoring for the night but want to keep informed of hazards. 09 16Every 2 seconds, the radio checks channels 9 & 16, then scans the next channel.Triple Watch onEvery 7 seconds, the radio checks the last-used weather channel, then scans the next channel. wxWX Alert Watch onMemory Channel Scan08 252417151413121110 20

To attach the antenna to your radio, screw it tightly onto the anchor post at the top of the radio. Installing the batteryYour MHS75 comes with a rechargeable Lithium Ion battery; for shipping safety, the battery is not installed at the factory. 1. Insert the hook onthe battery into the notch at the top of the batterycompartment.Note: Each time you remove the battery, check the rubber seal around the battery compartment. Make sure the seal is seated in the groove and there is no dirt or debris on it.

If your current area uses Canadian or international channel assignments, press the UIC-Lock key to rotatethrough the US, Canadian, and international channels.Maintenance and TroubleshootingDue to its rugged design, the MHS75 requires very little maintenance. However, it is a precision electronic instrument, so you should follow a few precautions:If the antenna has been damaged, do not transmit except in an emergency situation. Transmitting with a defective antenna may cause further radio damage.You are responsible for continued FCC technical compliance of your radio.You should arrange for periodic performance checks with your Uniden dealer.Common questionsProblem Things to TryThe radio won’t turn on.

E-26 Uniden MHS75 Radio Owner’s ManualRegulations and Safety WarningsMaritime radio services operationWarning! This transmitter will operate on channels/frequencies that have restricted use in the United States. The channel assignments include frequencies assigned for exclusive use of the U.S. Coast Guard, use in Canada, and use in international waters. Operation on these frequencies without proper authorization is strictly forbidden. See pages 28 through 32 for tables of the available channels and their uses. If you are still not certain which channels to use, see the FCC maritime radio page at the FCC website (http://wireless.fcc.gov/marine/) or contact the FCC Call Center at 1-888-CALL-FCC.

Basic radio guidelinesYou should familiarize yourself with the rules on marine radios and be aware of which rules apply to your boat. Complete guidelines for all ship and marine radio types can be found at the US Coast Guard website under the topic Radio Info for Boaters (the direct link ishttp://www.navcen.uscg.gov/marcomms/boater.htm).Here are a few guidelines that affect nearly all boaters.If you have a VHF radio on your boat, you must maintain a  watch on channel 16 (156.800 MHz) whenever the radio is not being used to communicate. Starting in 2004, if a radio is carried, it must be on and set to channel 16 whenever your boat is underway.If you hear a distress call, wait a few minutes to let a shore  station or Coast Guard vessel respond. If no other station has responded after 5 minutes, you must respond to the distress call. WARNING! Read this information before using the radio.

Those guidelines are consistent with the safety standard previously set by both U.S. and international standards bodies. The design of the radio complies with the FCC guidelines and these international standards.Never allow children to operate the radio without adult supervision and the knowledge of the following guidelines.WARNING! It is up to the user to properly operate this radio transmitter to insure safe operation. Please adhere to the following:

Please contact your local dealer for a replacement antenna.Body-worn Operation: This device was tested for typical body-worn operations using the supplied belt-clip. To maintain compliance with FCC RF exposure requirements, body-worn operations are restricted to the supplied belt-clip. For hand-held operation, the radio should be held 1 inch from the user’s face. The use of accessories that do not satisfy these requirements may not comply with FCC RF exposure requirements and should be avoided.
