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 be received at great 

distance. This is because broadcasting signals follow the curvature of the earth and are 

reflected back by the upper atmosphere.
