Squelch (SQ) Mode

The scanner can be set to the following SQ modes.

•Carrier SQ mode (default setting)

The scanner will stop on any transmission or squelch opening, regardless of whether any sub-audible tone has been programmed for the channel or search range.

•Tone SQ mode

The scanner will stop on any active frequency for which either no sub-audible tone has been programmed or for which the user-programmed sub-audible tone is also active.

•Tone Search mode

During any transmission, the scanner will begin searching all possible sub-audible tones, one of which may also be in use. The scanner counts up through the CTCSS tones and instantly determines any possible DCS tone. See Page 83 for a listing of the tones that the BC780XLT decodes.

Note: When Tone Search is active in Scan Mode, once the CTCSS/DCS display flashes a tone repeatedly (meaning that it has found the tone match), you can press E to program that frequency with the captured tone. When you change the mode to Tone Squelch from Tone Search, that frequency and tone will be programmed.

•Tone Lock (out) mode

For either a memory channel or a search range, you can lock a particular sub-audible tone by pressing L/O after scrolling to the desired tone. The scanner will stop on any transmission except those which may be using the locked sub-audible.

To set your scanner, enter into the menu mode.
