Monitor the channel for two-tone pages, single-tone pages, and group tones. This tone out search mode works as follows: - All detected tones are compared to the three criteria listed above.
- 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.
- If the detected tone matches a saved tone, the scanner opens squelch.
- 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.
