Checking the LED
Connect the power cable to the 'DC 5 V' connector on the right-hand end of the UbiCell and
plug the transformer into an available wall outlet using the cord that comes with it.
Turn on the UbiCell by pressing the 'Power' switch just above the 'DC 5 V'
connector.
The 'Power' LED on the left-hand end of the UbiCell should lit up blue.
Over the next few minutes the 'WAN LED, the 'GPS' LED, and the 'System'
LED should all lit up blue.(If after 10 minutes any of the LEDs is not lit up,
or is lit up red, see the 'Troubleshooting' instructions on the next page.)
That's all there is to it. You can now make and receive calls with your
Sprint Nextel handset using the UbiCell.
