Weather Band Operation
What is the NOAA Weather Radio/Weatheradio Canada?
NOAA (National Oceanic and Atmospheric Administration) is a
nationwide system that broadcasts local weather emergency
information 24 hours a day via the National Weather Service
(NWS) network. 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. Pacic
Territories. Each local area has its own transmitting station
and there are a total of seven broadcasting frequencies used.
A similar system is available in Canada under the Weatheradio
Canada service administered by Environment Canada.
Tuning to Weatherband
Press the MODE button (2) repeatedly to reach the
Weatherband. The indication "WB" will appear on the display
panel, along with the current number and channel indication:
Frequency (MHz) Preset
162.400 2
162.425 4
162.450 5
162.475 3
162.500 6
162.525 -
162.550 1
"WB-1", WB-2", "WB-3", "WB-4", "WB-5", "WB-6" or "WB-7". The
seven frequencies are shown in the following table:
WB Frequencies
The above table also shows which preset button will access
the frequency. Note that one frequency cannot be accessed
using a preset button. The frequency can only be reached
using the tuning controls.
Use the or buttons (6, 7) or the preset buttons to tune to
each of the seven channels until you nd the weatherband
station broadcasting in your area.
How many stations can I expect to receive?
Since the broadcasts are local weather and information,
the transmission power is usually very low (much less than
standard AM or FM stations) so you will usually receive
only one station unless you are on the edge of two or more
broadcast signals. The most you will receive will be two or
three, and that is rare.

12
Is it possible I won't receive any stations?
Depending on where you are located, there is a possibility
you will receive only a very weak signal or none at all. Also,
similar to AM and FM signals, weatherband signals are subject
to surrounding conditions, weather, obstructions of the signal
by hills or mountains, etc.
BLUETOOTH OPERATION
The JHD22 includes built-in Bluetooth technology that
allows you to connect this head unit to Bluetooth devices for
streaming audio playback.
About Bluetooth Technology
Bluetooth is a short-range wireless radio connectivity
technology developed as a cable replacement for various
electronic devices. Bluetooth operates in 2.4 GHz frequency
range and transmits voice and data at speeds up to 2.1 Mbit/s
over a range of up to 10 meters.

CARE AND MAINTENANCE
• Keep the product dry. 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 carefully. 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 new. 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 parts.
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 vehicles
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 radio or electronic supply shops.
Interference
Radio reception in a moving environment is very dierent
from reception in a stationary environment (home). It is very
important to understand the dierence.
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 reected
back by the upper atmosphere.
