• If all the boxes are red: the tracker is not receiving pulses from any speaker. Make
sure the tracker has a fresh battery, is “on” with mute “off” and that it is enabled.
Ensure the MLD external box and the tracker radio receiver are “on”. Go to
tracker calibration in the set-up screen to choose an ideal radio receiver volume.
• If only one box is red persistently and the others are green: may be the speaker in
question is not sending pulses. Check your speaker connections using the “Test
Speakers” button in the “Set-up” screen. If one of the speakers fails to pass the
test check the cabling to that speaker.
• If the boxes show intermittent yellow flashes: there are many echoes in the space.
Move the speakers slightly away from walls or reflective surfaces and/or decrease
the sampling frequency.
• If the boxes show random intermittent green and red flashes: unsteady tracking. Check
chapter 8 “Tips to Optimize System performance”
You may enable or disable tracking for any tracker by clicking on its enabling box, which
is the numbered box at the top of the columns representing the height of the trackers.
By default, only tracker 1 is enabled.
Maps and Sets
In real-time mode you may have up to four maps enabled simultaneously. As you go
from the main MLD screen to the real-time mode screen the map that was open gets
added to the “active map” list automatically. To add more maps you click on “Load
Map”. To remove any map you select it and click “Unload map”. You may save “Sets”
of up to four maps together so that you can load them in a single step. In addition, map
loading and unloading will take place automatically if this was defined in the “Map
control” dialog box when designing the map.
Side note: sets are not useful if you are loading and unloading maps with the map remote
control features.
