Subject: Extended Frequencies Justification for Certification of Transmitter with FCC ID: Q9SAWR-D6000

Dear Sir/Madam,

This transmitter was designed to operate in following frequency ranges: 400-480MHz

To aid equipment authorization in other countries which accept the United States FCC Grant for
Certification, Northfield Telecommunications, Inc. d/b/a Advanced Wireless Communications is requesting
that the FCC lists the frequencies 400-480MHz, under FCC Rule Parts 22 and 90 on the FCC Grant.

Northfield Telecommunications, Inc. d/b/a Advanced Wireless Communications attests that the Is Digital
Radio will not be marketed to USA users with the frequency band which is not allowed by the rule part 22
and 90. Per the FCC’s KDB634817 guidance, as an alternative to listing the exact frequencies, we
acknowledge that it’s a violation of the FCC Rules if this device operates on unauthorized frequencies.

complies with 47 CFR Part 90.203(e), in that the operator cannot directly program the transmit
frequencies using the normally accessible external controls.
