6. Do not wear the phone on your body while making calls with the
headset accessory. Wearing the phone on the body can interfere
with proper phone operation, since the antenna requires a clear
unobstructed view of the sky to access the Iridium satellite network.
7. Once you complete your call and are finished with the phone, return the
antenna to the center upright position and gently retract the antenna
before carrying or storing the phone between uses.
8. For backup, keep a written record of all important information stored on
your phone.
Note: Keep all covers fully and securely installed (SOS button cover,
headset cover, and bottom accessory connector cover) when not in use.
Failure to do so could result in dust and/or moisture being introduced to
the unit when the covers are open, which could in turn cause failure of
your device.
