COMMON PROBLEMS AND SOLUTIONS
Often after time spent troubleshooting, the problem is traced to something as simple as a loose
connection. Check the following before processing to the problem-specific solutions.
• Use some other electrical device to confirm that the electrical outlet is working.
• Ensure the DMA is turned on.
• Ensure all connection are securely attached.

Antenna Specification
The mini-PCI adaptter is available in two variants: unique coax con-
nectors with diversity function.
On baord Diversity Switch:
This variant of the Mini-PCI Card has connectors for two external
passive antennas: MAIN and AUX. One of the antennas is used for
transmission, and the DSP selects which of the two to use for recep-
tion, based on signal strenght.
The coax connectors for the antennas are mechanically unique, so that
no off-the -shielf connector will fit (FCC requirement).
Switch electronics for selection between the two antennas for recep-
tion of the stronger receive signal is provided onboard.
