    the.Fcc.Wants.You.to.KnoW This scanner has been tested and found to comply with the limits for a scanning receiver, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This scanner generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.

  • Page 8: Scanning.legally

    scanning.LegaLLY Your scanner covers frequencies used by many different groups, including police and fire departments, ambulance services, government agencies, private companies, amateur radio services, military operations, pager services, and wire-line (telephone and telegraph) service providers. It is legal to listen to almost every transmission your scanner can receive.

  • Page 16: Scanning.basics, What.is.searching

    What.is.searching? The BC125AT can search for active frequencies. This is different from scanning because you are searching for frequencies that have not been programmed into the scanner. When you select frequency bands to search, the scanner searches for any active frequency within the lower and upper limits you specify.

  • Page 17: What Is Ctcss/dcs

    understanding.scanning What is CTCSS/DCS? Your scanner can monitor systems using a Continuous Tone Coded Squelch System (CTCSS) and Digital Coded Squelch (DCS) system, which allows the squelch to open only when the tone you have programmed with a specific frequency is received along with a transmission.

    tone with a signal, the scanner’s squelch remains closed and you hear nothing. Refer to the Reference section of this manual for tables showing the available CTCSS frequencies and DCS codes. Conventional Scanning Conventional scanning is a relatively simple concept. Each group of users in a conventional system is assigned a single frequency (for simplex systems) or two frequencies (for repeater systems).

Repeater Operation Repeater systems use two frequencies: one transmits from the radio to a central repeater; the other transmits from the repeater to other radios in the system.
