If you desire to listen to AM stations, set the WX--AM--FM selector switch to the AM position now. You will notice the "ALERT" light comes on when power is supplied. Your WR-10 is listening for EMERGENCY signals from the Weather Service. Look up your city or a major city near you in the supplied Weather Service directory and set the switch on the bottom of your unit to the frequency listed. To test for weather signals, simply press the WEATHER bar on the top of your 74-105XL. This will switch the WR-10 from AM or FM to receive the Weather broadcast. 6 Once you have adjusted the weather frequency and are receiving weather broadcast stations, your WR-10 will automatically switch from AM or FM reception to the Weather mode if the weather Service sends the special tone to warn you of dangerous weather conditions. The setup procedure previously set your radio to "SIREN" mode. See the instructions under the ALERT mode section for adjusting this mode. NOTE: The National Weather Service operates Weather Broadcast systems covering a large area of the United States. Your WR-10 can receive broadcasts from the Weather Stations up to 50 miles. If your city is listed as having a Weather Service Station but you do not receive it please call your local Weather Service to confirm they are broadcasting (Sometimes these stations are shut down for maintenance). If your local Weather Service is transmitting and you are not receiving the broadcasts, you may need an outdoor antenna.

[. . . ] All National Weather Service stations periodically transmit an Alert test signal. You can always find out when the test signal is broadcast by calling the U. S. Mobile home reception is difficult due to the metallic structure preventing reception. If this doesn't provide reasonable reception-then a outside antenna must be used. [. . . ]
