Figure 4.1 Route Display with Multiple Routes Being Read
When the MRX920 unit starts collecting data, the
Reading indicator changes to display a pulsing green
arrow. This icon continues to pulse as long as read
data is received within a period of five seconds.
In normal use, you focus on driving and listening for beeps on the selected
route. You DO NOT need to look at the screen on the MRX920 unit while you
are driving. The MRX920 unit automatically receives and stores any readings
within range for any MIU IDs that are loaded on the laptop.
