I'm not sure what you've tried so far, but you need to give your PC the static address of 10.0.0.2. Plug your PC into your AP's Ethernet interface using a Crossover cable (this is required). Then, open a web browser and try to connect to 10.0.0.1.
The AP only holds the 10.0.0.1 for 5 minutes after boot, so reboot it if you aren't able to get to the address. If this still doesn't work, it likely hasn't been reset to factory defaults. Power it down, hold the MODE button, and turn it on. Hold the MODE button until you the AP lights turn red, which should be after about 30 seconds. Then release it and try the above to connect.
I did the procedure that you informed, press the MODE for 30 seconds until lights turn red, can not access the AP. PC configured with 10.0.0.2 and 10.0.0.1 put Gateway pattern, the mask that was used to 255.0.0.0, start web browse (IE) and I connected http://10.0.0.1 and failed.
