Control area

Button	Keyboard	Description
	l	When active, incoming audio will be played according to the active systems/talkgroups on the SELECT TG panel. The LED can also be yellow if playing audio from the archive while LIVE FEED is inactive, this is called offline playback mode. Disabling LIVE FEED will also stop any playing audio and will clear the listening queue.
	s	Temporarily maintain the current system in live feed mode.
	t	Temporarily maintain the current talkgroup in live feed mode.
	r	Replay the current audio from the beginning or the previous one if there is none active.
	n	Stop the audio currently playing and play the next one in the listening queue. This is useful when playing boring or encrypted sound.
	a	Activate and deactivate the talkgroup from the current or previous audio.
	←	Display the archived audio panel.
	p, space	Stop playing queue audio. Useful if you have to answer the phone without losing what's queued up for playing.
	→	Display the systems/talkgroups selection panel where you decide which audio you want to listen to in *LIVE FEED (not in offline playback mode).

Systems/Talkgroups selection panel

Here you select which systems/talkgroups/groups you want to listen to while in LIVE FEED mode.

The selection panel has no effect if you play calls from the archived audio panel.

Group selection section

The first section concerns group selection. This section can be disabled from the configuration file, but is active by default. Each button has three states:

Button	State
	All talkgroups, from any systems, that correspond to this group are actives. If you press it while it is active, it will make these talkgroups inactives.
	All talkgroups, from any systems, that correspond to this group are inactives. If you press it while it is inactive, it will make these talkgroups actives.
	Some talkgroups, from any systems, that correspond to this group are actives and some are inactives. If you press it while it is active, it will make all these talkgroups active.
	Make every groups inactives, thereby disabling all talkgroups.
	Make every groups active, thereby enaabling all talkgroups.

Systems/Talkgroups selection section

This is much like the group selection section, but for each system. There is also just states for each button:

Button	State
	The talkgroup from this system is active. If you press it while it is active, it will make the talkgroup inactive.
	The talkgroup from this system is inactive. If you press it while it is inactive, it will make the talkgroup active.
	Make inactive every talkgroups from this system.
	Make active every talkgroups from this system.

Archived audio panel

Archived audio list

This section presents the list of archived audio files. Depending on the LIVE FEED mode you are at, the replay function behaves differently:

Mode	Function
	while LIVE FEED is active, press the PLAY button to play this audio file. If another audio file is playing, it will be stopped and the one you just selected will be played instead. After playback finishes, the listening queue will resume as normal.
	This is the offline playback mode which can be activated only if LIVE FEED is inactive. Press the PLAY button to play this audio file. After playback is finishes, the next audio file from in list is played. While the audio is playing, pressing the STOP button will cancel the offline playback mode.

At the bottom right of this section is the paginator to browse the whole database. This paginator is disabled while in offline playback mode.

Note that offline playback mode always requires your web application to be online. It is called like that because it plays archived audio files.

Archived audio filter

This is the section where you filter archive audio to a specific date, system and talkgroup. You can also change the list order.

There is also a small slider that changes the PLAY buttons to DOWNLOAD buttons. This allows you to download audio files individually regardless of the playback mode you use.

Note that if you change any filter while in offline playback mode, it will deactivate it.

Finally

Happy Rdio scanning !
