2 This device must accept any interference received, including interference

that may cause undesired operation.

RF-exposure statement

When the product is equipped with a wireless interface, then it becomes a

mobile or fixed mounted modular transmitter and must have a separation

distance of at least 20 cm (8 inches) between the antenna and the body of

the user or nearby persons. In practice, this means that the user or nearby

persons must have a distance of at least 20 cm (8 inches) from the modem

and must not lean on the modem in case it is wall mounted. With a separation

distance of 20 cm (8 inches) or more, the M(aximum)

P(ermissible) E(xposure) limits are well above the potential this module is

capable to produce. For operation within 5.15 ~ 5.25GHz frequency range, it

is restricted to indoor environment. This device meets all the other

requirements specified in Part 15E, Section 15.407 of the FCCRules.

This transmitter must not be co-located or operating in conjunction with any

other antenna or transmitter.
