Radio Frequency Energy Safety Information
Warning
This JVC camera generates RF EME while
transmitting. RF EME (Radio Frequency Electric
& Magnetic Energy) has the potential to cause
slight thermal, or heating effects to any part of
your body less than the recommended distance
from this radio transmitter's antenna. RF energy
exposure is determined primarily by the distance
to and the power of the transmitting device. In
general, RF exposure is minimized when the
lowest possible power is used or transmission
time is kept to the minimum required for
consistent communications, and the greatest
distance possible from the antenna to the body
is maintained.
The following list provides you with the information
required to ensure that you are aware of RF
exposure.
While transmitting, always keep the antenna
0
and the radio at least 5 cm (1-31/32") from your
body or face, as well as from any bystanders.
To maintain compliance with FCC's RF
0
exposure guidelines, use only the supplied
antenna (with antenna holder).
Unauthrized antenna, modification, or
attachments could damage the transmitter and
may violate FCC regulations.
Electromagnetic Interference Compatibility
Electronic devices are susceptible to
electromagnetic interference (EMI) if they are not
adequately shielded or designed for
electromagnetic compatibility.
Because this product generates RF energy, it can
cause interference to such equipment.
Turn OFF your WLAN where signs are posted to
0
do so. Hospitals and health care facilities use
equipment that is sensitive to electromagnetic
radiation.
Turn OFF your product while on board an aircraft
0
when so instructed. Use of the product must be
in accordance with airline regulations and/or
crew instructions.
GY-HC550U
For indoor use only (5150-5250 MHz) in
Canada
There are legal restrictions on the use and
outdoor use depending on the country and
region. Please be careful not to violate the law.
Data transmission is always intiated by software,
which is the passed down through the MAC,
through the digital and analog baseband, and
finally to the RF chip. Several special packets are
initiated by the MAC.These are the only ways the
digital baseband portion will turn on the RF
transmitter, which it then turns off at the end of
the packet. Therefore, the transmitter will be on
only while one of the aforementioned packets is
being transmitted.In other words, this device
automatically discontinue transmission in case
of either absence of information to transmit or
operational failure.
Frequency Tolerance: 20 ppm
