If any of the responses return Not-Acquired or Not-Registered (and the APN is correct), the wireless
network operator should be contacted for further troubleshooting.
Please note that it may take several seconds (or longer) for the LMU-3040™ to communicate with
the modem and acquire the wireless network.
7.2 GPS Verification
The next step is to verify that the GPS receiver is seeing enough satellites to obtain a valid GPS
position. Again, installers have two choices on how to perform this verification. First, like the Comm
Verification, there is a GPS status LED (i.e., the one closest to the SMA connector). If this LED is
solid, then the LMU has found GPS service.
If the LED is not visible then GPS service may be verified using an AT Command:
AT$APP GPS?
The response should be similar to:
