Subject: Extended Frequencies Justification for Certification of Transmitter with FCC ID: POD-MDUV390

Dear Sir/Madam,

This transmitter was designed to operate in following frequency ranges:136-174 & 400-480MHz

To aid equipment authorization in other countries which accept the United States FCC Grant for
Certification, TYT ELECTRONICS CO., LTD is requesting that the FCC lists the frequencies 136-174 &
400-480MHz, under FCC Rule Parts 22 and 90 on the FCC Grant.

TYT ELECTRONICS CO., LTD 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.
