(2) Multipath
One type of interference caused by the bounce of
radio waves off of obstructions is called ”multipath”.
Multipath occurs when a signal from the broadcast
transmitter antenna bounces off buildings and
mountains and interferes with the signal that is re-
ceived directly.
(3) Fade Out Because FM radio waves are of higher frequencies
than AM radio waves, they bounce off buildings,
mountains, and other obstructions. For this reason,
FM signals often seem to gradually disappear or
fade away as the vehicle goes behind a building or
other obstruction. This is called ”fade out”.
4. COMPACT DISC PLAYER
Compact Disc (hereafter called ”CD”) Players use a laser beam
pick−up to read the digital signals recorded on the CD and re-
produce analog signals of the music, etc. There are 4.7 in. (12
cm) and 3.2 in. (8 cm) discs in the CD player.
HINT:
Never attempt to disassemble or oil any part of the player unit.
Do not insert any object other than a disc into the magazine.
NOTICE:
CD players use an invisible laser beam which could cause
hazardous radiation exposure. Be sure to operate the play-
er correctly as instructed.
5. Tape Player/Head Cleaning: MAINTENANCE
(a) Raise the cassette door with your finger.
Next, using a pencil or similar object, push in the guide.
(b) Using a clean ing pen or cotton applicator soaked in clean-
er, clean the head surface, pinch rollers and capstans.
