Triple WX Alert wx Watch on Watch on Weather mode The 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 mode

• You 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 Watch Because 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.

Release the Push to Talk button when you’re finished talking to let the other party respond.

• To prevent stuck microphone problems or situations where the Push to Talk button is pushed accidentally, the radio limits your talk time to 5 minutes in a single transmission.
• For the best sound quality, hold the microphone about two inches away from your mouth.
• See the channel lists starting on page 19 for a list of receive-only channels. Boosting the transmission power In most situations, the 1 Watt transmission power is all you need. If you find yourself far away from other stations and have trouble getting a response, you may need to boost the transmission power from 1 Watt to 2.5 Watts or 5 Watts:
• Press the 1/5W-2.5W button to switch from 1 Watt to 5 Watts. Press the button again to switch back to 1 Watt.
• To switch to 2.5 Watts, press and hold the 1/5W-2.5W button for about two seconds. Press and hold the button again to switch back to 1 Watt or 5 Watts (whichever you were on when you switched to 2.5 Watts).
• The transmit power remains at the new setting until you change it again. The transmit power icon always shows the current transmission power. Note: Don’t forget to change the transmission setting back to 1 Watt when you move close to other stations.
• Some channels (for example, channels 13 and 67) limit the transmission power to 1 Watt. When you tune to a limited-power channel, the radio automatically switches to 1 Watt. See the channel lists starting on page 19 for a list of power-restricted channels. E-16 Uniden MHS75 Radio Owner’s Manual Setting the UIC channel mode The radio comes preset to use the channels assigned for the US. If your current area uses Canadian or international channel assignments, press the UIC-Lock key to rotate through the US, Canadian, and international channels. Maintenance and Troubleshooting Due to its rugged design, the MHS75 requires very little maintenance. However, it is a precision electronic instrument, so you should follow a few precautions:

Uniden MHS75 Radio Owner’s Manual E-25 Regulations and Safety Warnings WARNING! Read this information before using the radio. Maritime radio services operation Warning! 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 19 through 25 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. For individuals requiring a license, such as commercial users, you should obtain a license application from your nearest FCC field office (for US users) or Industry Canada (for Canadian users). Basic radio guidelines You 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 is http://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. E-26 Uniden MHS75 Radio Owner’s Manual

• Do not make false mayday or distress calls as a prank or to test your radio. (This is essentially like making a false 91-1 call; you may be subject to fines.) FCC/Industry Canada information
• Transmitter Frequency Range: 156.025-157.425 MHz This device complies with Part 80 of the FCC Rules, as well as Part 15 of the FCC Rules.

FCC RF exposure information In August 1996 the Federal Communications Commission (FCC) of the United States with its action in Report and Order FCC 96-326 adopted an updated safety standard for human exposure to radio frequency electromagnetic energy emitted by FCC regulated transmitters. 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: Uniden MHS75 Radio Owner’s Manual E-27

• Use only the supplied or an approved antenna. Unauthorized antennas, modifications, or attachments could impair call quality, damage the radio, or violate FCC regulations.
• Do not use the radio with a damaged antenna. If a damaged antenna comes into contact with the skin, a minor burn may result. Please contact your local dealer for a replacement antenna.
