Storing Frequencies into Channels During Service Search You can store frequencies you found during service search or service search hold mode into channels. If you want to select another channel, press Func + or Func + before you press E. If you entered a frequency that has already been entered elsewhere, the scanner sounds an error tone and displays the channel that was duplicated.
