DCS - the scanner only opens squelch if the DCS tone you select is also present with the signal. The scanner then prompts you to scroll to the desired tone.

Set Lockout - the scanner does not stop on the channel if the tone you select is present. The scanner prompts you to select a CTCSS or DCS tone.

Notes:

•The default setting is Off.

•See “What is CTCSS/DCS?” on Page 16 for a complete list of CTCSS and DCS tones.
