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

Weather Band Operation

What is the NOAA Weather Radio/Weatheradio Canada?

This 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 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:

"CH01", CH02", "CH03", "CH04", "CH05", "CH06" or "CH07". Use the TUNE/SEEK >>| or |<<

buttons (19, 18) 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.

NOAA Weather Alert

The Weather Alert function adds an additional level of user safety by automatically switching

from any of the available function modes (Tuner, SAT, iPod, AUX) to weather band for a

minimum of 60 seconds if a NOAA warning tone (1050 Hz) is received/detected. If no

additional warning tone is received for 60 seconds, the unit will switch back to the last known

function mode. See “System Menu” on page 6 to learn how to turn the WB Alert feature on.

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

Cause

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.

Wiring is not properly con-

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.

Press the RESET button

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.
