  • Page 21: I Auto Repeater Function

    I Auto repeater USING function (USA version only) The USA version automatically activates the repeater settings (duplex, ON/OFF, duplex direction, tone encoder ON/OFF) when the operating frequency falls within or outside of the general repeater output frequency range. The offset and re- peater tone frequencies are not changed by the auto repeater function, reset these frequencies, if necessary.

  • Page 22: Repeater Operation

    REPEATER OPERATION WEATHER CHANNELS (USA version only) There are 10 weather channels for monitor- ing weather channels from the NOAA (Na- tional Oceanographic and Atmospheric Administration) broadcasts.
