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�
