INSTALLATION
This unit is designed for installation in vehicle cabs with an existing 1-DIN radio opening. In
many cases, a special installation kit will be required to mount the radio to the dashboard. See
the dealer where the radio was purchased for kit availability. Always check the kit application
before purchasing to make sure the kit works with your vehicle.

Before final installation, test the wiring connections to make sure the unit is connected
properly and the system works.
Use only the parts included with the unit to ensure proper installation. The use of
unauthorized parts can cause malfunctions.
Consult with your nearest dealer if installation requires the drilling of holes or other
modifications to your vehicle.
Install the unit where it does not interfere with driving and cannot injure passengers during
a sudden or emergency stop.
If the installation angle exceeds 30º from horizontal, the unit might not give optimum
performance.
Avoid installing the unit where it will be subject to high temperatures from direct sunlight,
hot air, or from a heater, or subject to excessive dust, dirt or vibration.
Rubber Bushing
Hex Nut (5mm)
vehicle installations
provide cavity for rear
support. In these applications, place the rubber bushing over the screw stud and insert
the radio.
CAUTION: The perforated rear support strap or rear rubber mounting bushing must
be used in the installation of the radio. Installation without either may result in
damage to the radio or the mounting surface and void the manufacturer’s warranty.
9. Test radio operation by referring to the operating instructions for the unit.
DIN Front Mount
1. Slide the mounting sleeve off of the chas-
sis if it has not already been removed. If it
is locked into position, use the removal
keys (supplied) to disengage it. The
removal keys are depicted in “Removing
the Unit” on page 3.
2. Check the dashboard opening size by
sliding the mounting sleeve into it. If the
opening is not large enough, carefully cut
or file as necessary until the sleeve easily
slides into the opening. Do not force the
sleeve into the opening or cause it to bend
or bow. Check that there will be sufficient

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 costal 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. A similar system is available in Canada under the Weatheradio
Canada service administered by Environment Canada.
Tuning to Weatherband
Press and hold the BAND/WB button (15) to access the Weatherband. The indication "WB"
will appear on the display panel, along with the current number and channel indication: "WB-1",
“WB-2", "WB-3", "WB-4", "WB-5", "WB-6" or "WB-7". The seven frequencies are shown in the
following table:
Table 1: WB Frequencies
Frequency (MHz)

162.400

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 TUNE/SEEK >>| or |<< buttons (19, 18) or the preset buttons to tune to each of the
seven channels until you find 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.
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.

CARE AND MAINTENANCE
TROUBLESHOOTING
•
Keep the product dry. If it does get wet, wipe it dry immediately. Liquids might contain
minerals that can corrode the electronic circuits.
Symptom

Solution
•
•
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 professional mobile electronics retailers.

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 received at great
distance. This is because broadcasting signals follow the curvature of the earth and are
reflected back by the upper atmosphere.
