Using Tone-Out Standby/Search See Setting up Tone-Out first.
Press Menu. Scroll to 'Tone-Out for...' and press E/yes.
Scroll to 'Tone-Out Standby' and press E/yes.
You can also assign Tone-Out to a Search Key.
The display will show the Tone-Out name, channel number (1-10), and tone settings.
Any transmission received on the frequency will not be heard but you will still see the
signal strength bars.
All Tone-Outs (channels) that have the same frequency (and modulation and
attenuation) as the one you select will also (and only) be monitored so you can
monitor up to 10 Tone-Out channels for one frequency. In this case, the scanner
displays each Tone-Out channel for two seconds. It does not scan them; Tone-
Out monitors the frequency for all Tone-Out channels with the same frequency.
Regardless of the current display, the scanner will alert on any received tone out that
matches a stored setting (channel) for the frequency.
If you press Hold while in 'Standby/Search' mode, the scanner temporarily exits and
you will be able to hear any transmissions on that frequency. No alerts sound, even
if a Tone-Out matches one you have programmed in hold mode. Press Hold again to
return to 'Standby/Search' mode.
