TroubleshootingandSupport
IftheredLEDisoncontinuously,this usually indicates that the
drivers have either not been installed or have not been installed
correctly.
IfthegreenLEDisashing, but you cannot communicate with
the Flasher LT, use the “minfo” utility on the drivers disk. It will
show if the Flasher LT is connected, the type of Flasher LT, and the
revisions of the boot loader and rmware on the device. If “minfo”
indicates no devices are found, check the Control Panel Device
Manager to see if Windows is indicating some sort of error with the
device.
IfnoLEDsarelit, this may indicate a failure of the Flasher LT
device. Insure that the USB port that it is plugged into is good by
using another USB device on the USB port.
