STORE END 1245.8500 NFM Bank 12--56---AUTO STORE appears on the display. You may want to let it run through the search range several times because during the first pass there may not have been any transmissions at that particular time on that frequency. 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 subaudible 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 subaudible tone has been programmed or for which the user-programmed subaudible tone is also active. • Tone Search mode During any transmission, the scanner will begin searching all possible subaudible 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 101 for a listing of the tones that the BC250D decodes. Note: When Tone Search is active in Scan mode, once the CTCSS or 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 SQ 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 subaudible 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 subaudible tone. To set your scanner, enter into the Menu mode. 1. Press MENU/BACK. 2.
