17. Observe ‘Turn off the RF communication device such as Mobile Phone’ signs, such as
those near stores of fuel, chemicals or explosives
18. The operation of some medical electronic devices, such as hearing aids and
pacemakers, may be affected if a WIDI-X8 is used next to them. Observe any warning
signs and manufacturer's recommendations.
19. Please do not use your WIDI-X8 near any precision instrument, which may cause
noise or abnormal operation to the instrument.
20. Switch off your WIDI-X8 at a refueling point, such as a petrol station, even if you are
not refueling your own car.
21. Do not store or carry flammable or explosive materials in the same compartment
where a radio transmitter, such as a WIDI-X8, is placed.
22. Electronic vehicle systems, such as anti-lock brakes, speed control and fuel injection
systems are not normally affected by radio transmissions. The manufacturer of such
equipment can advise if it is adequately shielded from radio transmissions. If you
suspect vehicle problems caused by radio transmissions, consult your dealer and do
not switch on your WIDI-X8 until it has been checked by qualified approved installers.
Efficient Use
For optimum performance with minimum power consumption, note the following:
Your WIDI-X8 has the internal antenna. Do not cover part of the internal antenna
of the WIDI-X8 with your hands. This affects communication quality, may cause
the WIDI-X8 to operate at a higher power level than needed and may shorten
communication and standby times.
Radio Frequency Energy
Your WIDI-X8 is a low-power radio transmitter and receiver. When it is turned on, it
intermittently receives and transmits radio frequency (RF) energy (radio waves).
The system that handles the communication controls the power level at which the
WIDI-X8 transmits.
Exposure to Radio Frequency Energy
Your WIDI-X8 is designed not to exceed the limits for exposure to RF energy set
by national authorities and international health agencies. * These limits are part of
comprehensive guidelines and establish permitted levels of radio wave exposure
for the general population. The guidelines were developed by independent
scientific organizations such as ICNIRP (International Commission on
Non-Ionizing Radiation Protection) through periodic and thorough evaluation of
scientific studies. The limits include a substantial safety margin designed to
assure the safety of all persons, regardless of age and health, and to account for
any variations in measurements.*Examples of radio frequency exposure

and electromagnetic fields (up to 300 G Hz)-International Commission on
Non-Ionizing Radiation Protection (ICNIRP)”. Health Physics, vol. 74. pp,
