sound, and the system outputs a canceling sound from the audio speaker.
AM (Amplitude Modulation)
Amplifier A device that increases the level of a signal by increasing the current or voltage.
Antenna A device used to send or receive electromagnetic waves thr ough the air.
ATA (PC Card) A type of card that has been tested for use in playing WMA, and MP3 music files in the PC Card slot. Sizes of up to 1 GB have been tested.
Audio remote switch The switches on the steering wheel that control the audio system.
Auxiliary jack Allows the customer to use a portable audio device to i nput audio recordings.
Balance A control that changes the relative volume of the left and right channels.
Band A range of frequencies between two definite limits. Bands are assigned by the Federal Communications Commission for specific uses.
