User Guide

Main screen

The main Rdio Scanner screen as three sections, the LED area, the display area and the controls area.

LED Area

The LED is illuminated when there is active audio and blinks if the audio is paused.

The colour is green by default but can be customised by the system or the talkgroup.

Display Area

  • First row
    • 09:26 - Current time
    • Q: 27 - Number of audio files in the listening queue
  • Second row
    • SERAM - System label
    • Fire Dispatch - Talkgroup tag
  • Third row
    • SG2 - Talkgroup label

Control Area

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, called playback mode. Disabling LIVE FEED will also stop audio playing and clear the listening queue.
Temporarily maintain the current system in live feed mode.
Temporarily maintain the current talkgroup in live feed mode.
Replay the current audio from the beginning or the previous one if none is active. Press repeatedly to replay items displayed in the history section. For example, press three times to replay the third history item.
Stop the audio currently playing and play the next one in the listening queue. This is useful when playing dull or encrypted sound.
Activate and deactivate the talkgroup from the current or previous audio. Pressing the AVOID button multiple times when on the same call will go through AVOID -> AVOID 30M -> AVOID 60M -> AVOID 120M where the last ones will be AVOID for a specific number of minutes.
Display the archived audio panel.
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 FEEDmode, not in playback mode.

Select panel

Here you select which systems/talkgroups/groups you want to listen to while in LIVE FEED mode. Note that the selection panel has no effect if you play calls from the search panel.

Groups 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:

Search panel

List section

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

At the bottom left of this section is the toggle switch which allows you to toggle between play buttons and download buttons. The later ones allows you to download locally the audio file.

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

Note that playback mode always requires your web app to be online. It is called like that because it plays archived audio files from the database.

Filters section

This is the section where you filter the archived audio to a specific date, system, talkgroup, groups and tags. You can also change the sort 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 playback mode, it will deactivate it.
