Visibility of Diagnostic LEDs
Status LED lights on the front of the NexTraq device unit can provide valuable information
about the operation of the NexTraq device. When feasible, attempt to install the NexTraq
device in such a way that these lights can be seen with reasonable ease.
You may find it useful to be able to view the LEDs periodically to make sure that the HT
DEVICE is operating properly. If at any time you should encounter a problem with the HT
DEVICE, you may need to read the LEDs in order to troubleshoot the problem. If you
cannot fix the HT DEVICE yourself, you will need to provide the LED information to
NexTraq customer support.
For information about how to interpret the LEDs, see the Status LED Behavior section.
The only sequence of flashing that indicates a problem is 4 blinks per second On/1 second
Off. The orange light will always outshine the green light if both are on constant (both GPS
and radio are connected).
