Tone-Out Search Mode
When both Tone A and Tone B are set to 0.0Hz, this channel will be treated as a Tone-Out Search channel.
The scanner starts the Tone-Out Search. During monitoring the Tone-Out frequency, the speaker is muted
until Tones are detected.
In Tone-Out Search mode, if a transmission is detected, the scanner starts to check for two-tone pages,
single-tone pages and group tones.
For two-tone pages, Tone A must be present for more than 250ms, Tone B must be present for more than
100ms, and the time gap between Tone A and Tone B must less than 500ms.
For single-tone pages, the Tone must be present between 1.25-3.75 seconds.
For group tones, Tone must be present for more than 3.75 seconds.
If one kind of these tones is detected, the scanner begins to check whether it has been registered in
another tone-out channel with the same setting for frequency, Modulation and Attenuator. If it has been
registered, the scanner goes to Tone-Out Hold Mode with the registered channel number. If not, the
scanner goes to Tone-Out Hold Mode with the current Tone-Out search channel number.
Note: A Tone-Out Search channel is not treated as Multi-Channel even it has the same setting of
frequency, Modulation and Attenuator with other channels.
When in Tone-Out Search Mode, scanner will not switch the channel display each 2 seconds for the Multi-
Channel.
