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

TROUBLESHOOTING

Solution

Radio will not turn
ON or No front panel
