With this complete, remove the bottom cover, install L4, and then install top and
bottom covers. You are done and ready to put your Cyclone on the air!
TROUBLESHOOTING
If your Cyclone does not operate after assembly, repeat the visual inspection of
solder joints. Compare the component placement diagram with the instructions
to be certain that all components were installed in their correct locations.
A check of voltages at strategic locations on the board while under power can
serve to isolate problems to a particular circuit. The following table lists nominal
voltages on the unit on transmit and receive. If an entry is marked 'xxx'
do not
attempt to measure it during transmission
.
