The following list provides you with the information required to ensure
that you are aware of RF exposure.
● While transmitting, always keep the antenna 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 exposure guidelines, use

only the supplied antenna (with antenna holder).
Unauthrized antenna, modification, or attachments could damage
the transmitter and may violate FCC regulations.

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 do so. Hospitals

and health care facilities use equipment that is sensitive to
electromagnetic radiation.

● Turn OFF your product while on board an aircraft when so

instructed. Use of the product must be in accordance with airline
regulations and/or crew instructions.

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.

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

This radio transmitter (6549A-W8997M1216) has been approved
by Innovation, Science and Economic Development Canada to
operate with the antenna types listed bellow, with the maximum
permissible gain indicated.
Antenna types not included in this list that have a gain greater than
the maximum gain indicated for any type listed are strictly
prohibited use with this device.

Before use, read “Safety Precautions” and “Instruction Manual” carefully, and then operate the product correctly.
After reading the documents, store them in a place easily accessible at any time.
● Description of some items may overlap with content in the Instruction Manual.

This transmitter must not be co-located or operated in 
conjunction with any other antenna or transmitter.

This device contains licence-exempt transmitter(s)/
receiver(s) that comply with Innovation, Science and 
Economic Development Canada’s licence-exempt 
RSS(s). Operation is subject to the following two 
conditions: 

1. This device may not cause interference.
2. This device must accept any interference, including

interference that may cause undesired operation of
the device.

The available scientific evidence does not show that any 
health problems are associated with using low power 
wireless devices. There is no proof, however, that these 
low power wireless devices are absolutely safe. Low 
power Wireless devices emit low levels of radio 
frequency energy (RF) in the microwave range while 
being used. Whereas high levels of RF can produce 
health effects (by heating tissue), exposure of low-level 
RF that does not produce heating effects causes no 
known adverse health effects. Many studies of low-level 
RF exposures have not found any biological effects. 
Some studies have suggested that some biological 
effects might occur, but such findings have not been 
confirmed by additional research.  
The RF module, W8997-M1216 has been tested and 
found to comply with FCC/ISED radiation exposure 
limits set forth for an uncontrolled environment and 
meets the FCC radio frequency (RF) Exposure 
Guidelines and RSS-102 of the ISED radio frequency 
(RF) Exposure rules.
