Ignition and Interference Noise
Ignition Noise
The most common source of noise in reception is the ignition system, due to the fact that the radio is placed relatively 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.Generally, the ignition noise can be suppressed considerably by using a radio suppression
Interference Noise
Radio reception in a moving environment is very different from stationary reception. For example, AM reception will deteriorate when passing through a tunnel or under
Maintenance
System Maintenance
The following maintenance tips will extend the life and optimize the performance of the unit.
•Keep the unit dry. If it is exposed to moisture, wipe it dry immediately. Liquids may contain minerals that can corrode the electronic circuits.
•Keep the unit away from dust and dirt, which can cause premature wear of parts.
•Handle the unit carefully; dropping it can damage circuit boards and cases, causing the product to malfunction.
•Clean the unit occasionally by wiping it with a damp cloth. Do not use harsh chemicals, cleaning solvents or strong detergents to clean the product.
•Use and store the unit only in mild temperature environments. High temperatures can shorten the life of electronic products, damage batteries and distort/melt plastic parts.
System Maintenance
Periodic cleaning of the tape head and capstan shaft will ensure good reproduction of music and
•Use a
•While holding the tape door open, locate the tape head to the right of the opening and in the center of the unit.
•Clean the tape head with the cotton swab.
•Clean the capstans and the pinch rollers with the cotton swab.
•Allow the tape head, capstans and pinch rollers to dry before operating.
