Tone A and Tone B Settings

You can configure the scanner to search for tones in several different ways, based on the values you enter for Tone A and Tone B:

  Tone A setting Positive number Tone B Setting Positive number
Operation Monitor the channel for two-tone pages only. The scanner opens squelch and displays the tone information when the following occur:
  1. The scanner detects a tone that matches the value you set for Tone A.
  2. The tone is at least 250 ms long.
  3. Within 500 ms, the scanner detects a second tone that matches the value set for Tone B.
  4. The second tone is at least 100 ms long.
  Tone A setting Positive number Tone B Setting 0.0 Hz
Operation Monitor the channel for single-tone pages only. The scanner opens squelch and displays the tone information when the following occur:
  1. The scanner detects a tone that matches the value you set for Tone A.
  2. The tone is at least 1.25 seconds long and not more than 3.75 seconds long.
  Tone A setting 0.0 Hz Tone B Setting Positive number
Operation Monitor the channel for group tones only. The scanner opens squelch and displays the tone information when the following occur:
  1. The scanner detects a tone that matches the value you set for Tone B.
  2. The tone is at least 3.75 seconds long.

Tone A setting 0.0 Hz Tone B Setting 0.0 Hz
Operation Monitor the channel for two-tone pages, single-tone pages, and group tones. This tone out search mode works as follows:
  1. All detected tones are compared to the three criteria listed above.
  2. If the tone meets any one of the criteria, the scanner checks to see if this tone frequency is already saved to a tone out channel with the same frequency, modulation, and attenuator settings.
  3. If the detected tone matches a saved tone, the scanner opens squelch.
  4. If the detected tone does not match any saved tones, the scanner opens squelch, flashes the tone information on the display, and asks if you want to save the tone information.
