  Subject: Extend Frequencies Justification Original Application FCC ID: 2AJTU‐S6

  Dear Sir or Madam;
  This Digital radio was designed to operate in the frequency bands 410‐470MHz;
  To aid equipment authorization in other countries that accepts the United States FCC Grant
  for Certification, South Surveying & Mapping Technology Co., Ltd. is requesting that the FCC
  list the frequencies 410‐470MHz under FCC Rule Parts 90 and the Grant note code “EF”. For the
  FCC’s Rule Part 90 applications, this radio is used in systems by Federal and Public Safety
  agencies including Police, Fire, and Emergency Medical Services, etc. as indicated in the
  table below. Equipment programming is the responsibility of Authorized Service Personal. Also,
  the radio complies with 47 CFR Part 90.203 (e), in that the operator cannot directly program
  the transmit frequencies using the normally accessible external controls.
  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.
