Equipment programming is the responsibility of Authorized Service Personnel. In addition, 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.
Truly yours,
Sincerely,
