The TE8200 enables the AR8200, AR8600 to ignore certain transmissions which would otherwise stop the scan and search process.
Constant tones are often transmitted by public utilities and railways making their transmissions troublesome and fatiguing to monitor without the use of the TE8200.
There are 256 values for the tone eliminator ranging from 0 to 255 representing a frequency range of 0.4 to 4.2 kHz. Note: The audio tone is not removed from the audio path to the speaker but are used as a squelch trigger so that scan and search functions resume automatically when the selected tone is encountered.
