5: Using Iridium GO! and Your Smartphone

5
Iridium GO! requires connection to the Iridium Satellite Network. The swivel antenna should be
vertical to the ground and have a clear unobstructed view of the sky. The antenna must be able to
"see" the entire sky from approximately 8 degrees above the horizon. Nearby tall buildings or similar
structures, heavily leafed trees and mountains can all degrade performance as they block the signal
between the antenna and the satellites. Having a completely open view of the sky plays a very
important role in maximizing performance, as the Iridium satellites move across the sky from North
horizon to South horizon during a connected call.

Tips on Efficient Operation
For Iridium GO! to operate most efficiently:
1. Keep the battery charged to ensure that the device is ready for use when needed.
2. Ensure antenna is pointed directly up while in use.
3. Make sure the antenna has a clear unobstructed view of the sky.
4. Do not touch the antenna unnecessarily when Iridium GO! device is in use, as contact with the
antenna affects call quality and may cause the phone to operate at a higher power level than
otherwise needed.
5. Iridium GO! is not designed to be worn on your body.
Using the External Antenna
When the external Antenna Adaptor cable is plugged in, ensure
the Swivel antenna remains raised. Lowering the swivel antenna
will end the Iridium transmission.
