The National Weather Service uses several special radio frequencies
to provide continuous reports of the local weather conditions and
forecasts throughout the United States. Taped weather messages
are repeated every four to six minutes on a 24-hour basis and are
routinely revised every one to three hours, or more frequently if
needed.
During severe weather, the routine weather broadcasts will be inter-
rupted with special weather warning messages.
The JMCB-2003K-BW is designed to receive all these special
weather frequencies plus three international marine frequencies.
An NOAA Weather Radio Network Frequency pamphlet is enclosed
to identify the frequencies specifically broadcast for your geographi-
cal area.
The JMCB-2003K-BW receives CB, National Weather Service and
international marine weather broadcast frequencies as listed below:
CB Channels 1-40 26.965 to 27.405 MHz

Noise and Interference: Motorcycle audio systems are by their very
nature noisy. While we do not guarantee this system to be com-
pletely free from electrical noises and interference, we have taken
many steps to achieve that goal: the power supply system is well
filtered and the cables associated with the unit are shielded.
Most modern day motorcycles have resistor-type spark plugs installed
bythefactory.Itmaybenecessarytoinsurethatresistor-typespark
plugs are installed on your motorcycle.
Care, Cleaning and Protection: Your JMCB-2003K-BW unit has been
designed to withstand most weather conditions likely to be encoun-
tered in the motorcycle riding environment.
This unit is NOT however designed to be submerged or to withstand
a high pressure spray from commercial car wash nozzles and the
warranty will be void on any unit that has been subjected to these
conditions.
The included slip-on elastic cover should be installed over your
JMCB-2003K-BW unit when washing your motorcycle or whenever
your motorcycle will be left out in the weather or direct sunlight for
extended periods of time.
To clean your JMCB-2003K-BW, use a soft damp cloth and avoid any
harsh cleaning solvents or abrasives, as these may damage the finish
or structural integrity of your CB unit.
