WEATHER BAND OPERATION

Accessing the Weather Band

Press the MODE button (4) to access the weather band mode.
What is the NOAA Weather Radio?
NOAA is a nationwide system that broadcasts local weather emergency information 24 hours a day. The U.S. network has more than 530 stations covering the 50 states, as well as the adjacent coastal waters, Puerto Rico, the U.S. Virgin Islands and the U.S. Pacific Territories.
Each local area has its own transmitting station and there are a total of seven broadcasting frequencies used: 162.400MHz (CH2), 162.425MHz (CH4), 162.450MHz (CH5), 162.475MHz (CH3), 162.500MHz (CH6), 162.525MHz (CH7) and 162.550MHz (CH1).

How many stations can I expect to receive?

Since the broadcasts pertain to local weather and information, the transmission power is usually very low (much less than AM or FM stations) which means you will usually receive only one station unless you are on the edge of two or more broadcast signals. The most you will receive is two or three, and that is rare.
s it possible I won’t receive any stations?Depending on location, it’s possible to receive a very weak signal or none at all. Also, similar to AM and FM signals, weather band signals are subject to surrounding conditions, weather, obstructions of the signal by hills or mountains, etc. If no NOAA signals are found, the tuner will scan all seven NOAA frequencies every 30 seconds.

How will I know I am tuned to the weather band?

When you select the weather band, the “WB” icon will appear on the display panel, along with the current channel indication. Press the SEEK/TUNE/TRK |<< or >>| buttons (13, 14) to tune to each of the seven channels until you find the weather band station broadcasting in your area.

NOAA Weather Alert

The Weather Alert function adds an additional level of user safety by automatically switching from the current function mode to weather band mode for a minimum of 60 seconds if a NOAA warning tone (1050 Hz) is received. If no additional warning tone is received for 60 seconds, the unit will switch back to the last known function mode.

The Weather Alert function can be turned “on” or “off” by the Audio/Menu key, as described on page three. When set to “ON”, the weather tuner remains active in the background, even when the radio is turned off (as long as the power is still applied to the radio). If a weather alert is issued, the radio will turn on and play the announcement, then turn back off and revert to weather alert monitor mode.

The radio will not respond to any weather alerts when it is off and will not automatically switch to the weather band if an alert is issued.

NOTE: If the unit is programmed for European operation, the WB function

will be disabled.

CARE AND MAINTENANCE

• Keep the product If it does get wet, wipe it dry immediately. Liquids might contain minerals that can corrode the electronic circuits.
• Keep the product away from dust and dirt, which can cause premature wear of parts.
• Handle the product gently and Dropping it can damage circuit boards and cases, and can cause the product to work improperly.
• Wipe the product with a dampened cloth occasionally to keep it looking Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the product.
• Use and store the product only in normal temperature environments. High temperature can shorten the life of electronic devices, damage batteries, and distort or melt plastic

Ignition

The most common source of noise in reception is the ignition system. This is a result of the radio being placed close to the ignition system (engine). This type of noise can be easily detected because it will vary in intensity of pitch with the speed of the engine.

Usually, the ignition noise can be suppressed considerably by using a radio suppression type high voltage ignition wire and suppressor resistor in the ignition system. (Most vessels employ this wire and resistor but it may be necessary to check them for correct operation.) Another method of suppression is the use of additional noise suppressors. These can be obtained from most CB/A radio or electronic supply shops.

Interference

Radio reception in a moving environment is very different from reception in a stationary environment (home). It is very important to understand the difference.

AM reception will deteriorate when passing under a bridge or when passing under high voltage lines. Although AM is subject to environmental noise, it has the ability to be received at great distance. This is because broadcasting signals follow the curvature of the earth and are reflected back by the upper atmosphere.

TROUBLESHOOTING

properly connected to the vessel’s accessory terminal, switch the

ignition key to “ACC”.
