Cautions
Cautions indicate practices that could harm the QUATTRO 4.0 or other objects.
CAUTION: Some electronic devices that are not properly shielded will generate
electromagnetic interference (EMI) that may cause buzzing or odd sounds in the
Quattro 4.0 (or any headset for that matter). Examples include, PC’s, automobiles
and large screen TV’s.
CAUTION: Turn off the QUATTRO 4.0 in any facility where posted notices instruct
you to do so. Hospitals or health care facilities might include equipment that is
sensitive to external RF energy that can cause electromagnetic interference.
CAUTION: While onboard aircraft, turn off the QUATTRO 4.0 in accordance with
airline regulations and crew instructions.
CAUTION: If you use any personal medical device, consult the manufacturer
of the device to determine if it is adequately shielded from RF energy. Your
physician may be able to assist you in obtaining this information.
CAUTION: Avoid dropping the QUATTRO 4.0.
