Other safety issues
In order to avoid the potential for confusing the phone as a weapon, the
phone features a distinctive flame orange band at the tip of the antenna,
which is a convention used by manufacturers of various devices and is
familiar to safety officers in the country of manufacture and other
countries. Do not remove or cover the band, and avoid using or handling
the phone in a threatening manner or so as to suggest that the phone is a
weapon.
