Digital Weather Receiver with NWR-SAME decoding, thermometer and Digital clock with 2 alarms

PRODUCT INFORMATION

The 74-250 N.W.R./ S.A.M.E. (National Weather Radio/Specific Area Message Encoding) Weather/All Hazard Monitor provides you with constant monitoring of your local National Weather Service broadcast for messages warning you of hazardous conditions. The NWR/SAME decoding allows you to hear only messages concerning the area concerning you. You now have a choice as to what information will be brought to you. No more will you be awakened to hear of a problem many miles from your home that will not affect you. A clock with alarm is also featured.

The 74-250 NWR/SAME Weather/All Hazard Monitor is the latest advance in Weather monitoring technology providing you with the information you need for your greatest safety from the effects of weather and other external hazards.

FEATURES:

VHF Weather Monitor with seven different National Weather Service channels in the 162 MHz FM band – Provides 24- hour-a-day National Weather Service information from seven different channels for maximum reception possible (in areas where available)

Alert monitor system receives NWR/SAME codes transmitted by National Weather Service stations warning of dangerous weather conditions and other general hazards. The SAME codes designate which counties or parts of counties are affected by the individual message. When the alert feature is activated, the receiver remains in a standby mode. As SAME coded messages are received, the receiver automatically activates to warn you of dangerous weather conditions.

NWR-SAME:

In 1994, the National Oceanic and Atmospheric Administration (NOAA) began broadcasting coded emergency signals that identify the specific geographic area (such as a county) affected by an emergency. Until that time such specific emergency weather information was sent in other ways to broadcast stations and others then relayed to the public.

NOAA transmits the coded weather emergency signals using a technique called SAME (Specific Area Message Encoding). The

4

Midland 74-250 7-channel weather/ all hazards monitor is designed to receive these SAME transmissions.

Your Midland 74-250 can be programmed with up to 9 predefined county/channels that will define which notices broadcast by your local NOAA weather station will cause the radio to alert you. This includes warnings, watches and statements of weather and other area emergencies, about 40 different types.

Also included in the SAME message is the amount of time for which the message is effective. The 74-250 will continue to display the alert until its time expires. In the upper left of the display will be the time the alert was received.

You don’t need to wait for the 74-250 to give you an alert. Just find the NWR station broadcasting to your area from the 7 available channels. You can listen at any time, day or night to the latest weather information from the National Weather Service.

See quick use guide What is a FIPS Code?

The NWR divides the United States and territories by state and county (or parish) and assigns a six digit code number called a FIPS (Federal Information Processing System) code or also known as a NWR/SAME county code. The first digit identifies subdivision. The next two identify the state or territory, and the last three identify the county. For example the code for Clay county Missouri is 029047. The“047” indicates the county, the “29” indicates the state, and the “0” indicates the subdivision of the county. In this case and most cases the code will have a zero for the first digit, indicating that no subdivision is in use. The NWS plans to introduce subdivisions of some counties in the future, assigning digits 1 through 9 to the parts resulting in codes like 529047.

5

Acquiring FIPS codes for the desired Area:

The FIPS codes can be found by calling the NWS toll free number

1-888-NWS-SAME

(1-888-697-7263) Please be sure you are dialing the correct number

Automated instructions will guide you to the numbers you need.

The FIPS codes and much more information can be found by way of the Internet at www.nws.noaa.gov/nwr/indexnw.htm

Note: You might want to obtain the codes for other counties close to you or those you might frequently travel through. The counties still must be within the coverage area of your NWS broadcast.

This is what to expect when you call the NWS number. You will be prompted to enter your state. We suggest spelling the entire state to expedite the process. Next you will be prompted to enter the county. Again spell the entire county. We suggest you locate several counties surrounding you especially the county in the direction most of the storms will be coming from. When you have entered the county, the system will ask you to confirm what you entered is correct. Be ready to write the number. The system tells you the number fairly quick but you have the option to have it read back to you so you can get the whole number. Remember the number will be six digits long usually beginning with a zero.

INITIAL SETUP

To Install Batteries:

1.Hold the radio face down. Press the latch so it swings away from the cover.

The FIPS code 999999 is the all county code. You may continue to use this code that allows the radio to receive all alerts regardless of county. By selection of one of the memory locations, you may find the best NWS channel to listen to.

7

When you have finished with entering the county code and the channel associated with it, the radio will automatically revert back to the last county the radio was on. This means that when you finish with programming a county/channel you must be sure of the memory location you programmed. If you programmed county 2 and the radio was on county 1, when you are finished programming the radio it will be on location 1. You must cause the radio to switch to the county you just stored in a memory other than 1. Below are detailed instructions on programming the radio.

Before programming the radio, we suggest turning off the NOAA receiver. To temporally deactivate the receiver, press and hold the SNOOZE/FUNC button until you do not see the NOAA or any of the speaker icons associated with it. The display should

The SAME message the NWR sends contains information, which tells the radio the time period for which the alert is valid. The time can be set from 15 minutes up to 6 hours and what type of

16

the alert is issued. When the designated time has passed the display message and LED will be reset to their normal state.

Reviewing Overlapping Alerts

The 74-250 radio can store up to five different alerts (with overlapping effective times) in its memory. If the radio receives a new alert while a previous alert is still in effect, the radio automatically displays the alert description and sounds the alert for the new alert message. To scroll backward and forward through the radio’s memory and review all the effective alerts, press the “UP /DOWN” Buttons. Each alert will be displayed with the time it was received.

When a Test or Demo Alert Occurs

NWR sends a weekly test and occasional demonstration signals to let everyone with weather monitor receivers verify the operation of their equipment.

To find out the test schedule of for your area, contact the local NOAA or NWS office. Look for the number under US Government, Department of Commerce.

NOTES AND

MAINTENANCE

1.The typical weather (162MHz) reception distance will range from 25-50 miles depending on your location and conditions of weather, terrain, etc. Also, some Weather Stations operate at much higher power levels than others and have their transmitting towers on the top of high buildings or hills. If reception in your area is not good, check with your local dealer for assistance and ask about typical reception range in your area. Also try different locations to find a place of good reception.

2.If Weather Stations cannot be heard on any channel, contact your local National Weather Service office to verify that the station is on the air and also verify the CHANNEL (Frequency) and location of the weather station.

3.All National Weather Service stations periodically transmit an Alert test signal. Some broadcast only once a week and others more often. You can always find out when the test signal is broadcast by calling the U.S. Weather Service's phone number for your local NOAA station.

4.Mobile home reception is difficult due to the metallic structure preventing reception. Put your 74-250 near a window.
