If the asset was inside of a building, under/next to a large obstacle, or has the battery power OFF, have the customer do the following:
Turn the key power ON if the power was OFF.
Attempt to move the asset to a more open location with a clear line of sight to the sky.Select the "Refresh" on the equipment page in Product Link Web.
If the equipment was ON, and in a good location for data transfer, have the customer check to see if the radio disable switch was disabled. The radio disable switch is a switch between the control module and radios. When the radio disable switch is enabled, the power to the radios is off. If the radio disable switch was enabled, then have the customer disable the radio disable switch, and attempt a "Refresh" on the equipment page in Product Link Web.On-Site Diagnostics
