CTCSS Scan Operation This feature will scan all CTCSS codes for a single channel. It will pause to play any active transmissions then resume scanning 5 seconds after ending transmission. When in CTCSS scan mode the receiver will ignore uncoded transmissions. This feature is useful to establish communications with other users utilizing CTCSS coded transmissions. To activate the tone code (CTCSS) scan mode, - From FRS standby mode, press the MODE button twice to select the CTCSS function. - Press the SCAN button; the radio will begin scanning for all tone codes (01-38) relative to the current main channel selection. - To disable the tone code scan, press the SCAN button again, and the radio will return to normal operation with the same tone code at which the CTCSS scan function was stopped. Auto Key Lock Selection Mode This feature prevents accidental channel change to the preferred settings of the unit. The Auto Key Lock function temporarily disables the Up, Down and Mode Buttons.
