citizens band (CB) radios, or turn ON personal communication devices,
such an cellular phones, while your Lexis Light is turned ON;
2) Be aware of nearby transmitters, such as radio or TV stations, and try to
avoid coming close to them;
3) If unintended movement or brake release occurs, turn your Lexis Light
power switch OFF as soon as it is safe to do so;
4) Be aware that adding accessories or components, or modifying your
Lexis Light, may make it more susceptible to EMI (Note: There is
no easy way to evaluate their effect on the overall immunity of your Lexis
Light);
5) Report all incidents of unintended movement or brake release to your
Authorized Lexis Light dealer or service center, and note whether
there is a source of EMI nearby.
