CTCSS/DCS for non-repeater channels

[WRYP302]

I am new to GMRS, and recently purchased two BTECH GMRS-PRO handhelds and the BTEC GMRS-50V2 for my truck.  My question is on CTCSS & DCS tones.  I have a basic idea of their purpose, but I noticed that it appears the RT Systems programming software is adding tones to the CTCSS (67.0 Hz) and DCS (23) fields.  I noticed that the tones are present in the RT Systems default program (Tone Mode = None) and these tones were added when I downloaded the programming from the radio (the radio was programmed with the BTECH CPS software and CTCSS/DCS were set to OFF). 

I am saying it "appears" because the Tone Mode field = None.  Would it be correct to assume that as long Tone Mode = None that any entries in the CTCSS & DCS fields are ignored?

 

Thanks

Correct. If the tone type is none, then regardless of a tone code being present, it will not enable tone squelch. Same for DCS.
