THE FOLLOWING APPLIES ONLY IN THE U.S.A.
THE FOLLOWING APPLIES ONLY IN CANADA.
Contains FCC ID: VPYLB1JS955
This transmitter must not be co-located or operated in conjunction with any other antenna or
transmitter.
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment and meets the FCC radio frequency (RF) Exposure Guidelines as this equipment
has very low levels of RF energy.
Compliance with FCC requirement 15.407(c)
Data transmission is always initiated 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: ± 20ppm
Contains IC: 772C-LB1JS955
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. HC-X2000/
HC-X1500 (HMN is 1JS2099) has been tested and found to comply with ISED radiation
exposure limits set forth for an uncontrolled environment and meets RSS-102 of the ISED radio
frequency (RF) Exposure rules.
