Two Types of Signals
There are two basic types of radio signals... AM or
Amplitude Modulation, in which the transmitted sound
causes the amplitude, or height, of the radio waves to
vary... and FM or Frequency Modulation, in which the
frequency of the wave is varied to carry the sound.
Electrical Disturbances
Radio waves may pick up electrical disturbances during
transmission. They mainly affect the wave amplitude,
and thus remain a part of the AM reception. They
interfere very little with the frequency variations that
carry the FM signal.
AM Reception
AM sound is based on wave amplitude, so AM reception
can be disrupted by such things as lightning, power lines
and neon signs.
FM Reception
Because FM transmission is based on frequency varia-
tions, interference that consists of amplitude variations
can be filtered out, leaving the reception relatively clear,
which is the major feature of FM radio.

being played), press the PTY button. The lighted arrow in
the display window will show the new direction.
Metal Tape Selection
If a standard metal tape is inserted into the player, the
player will automatically select the correct equalization
and the 70 symbol will appear in the display window.
Pinch Roller Release
If ignition power or the radio ON/OFF switch are turned
off, the pinch roller will automatically retract to protect
the tape from any damage. When power is restored to the
tape player, the pinch roller will automatically reengage
and the tape will resume play.
Noise Reduction
The Dolby Noise Reduction System* is on whenever the
tape player is on, but may be switched off.
To turn off the Dolby Noise reduction System: Press the
Dolby button (button 2) after you insert the tape. The NR
light in the display will go off when the Dolby System is
off. The Dolby System is automatically reactivated each
time a tape is inserted.
