Band Scope mode

• In a band scope search, the scanner starts at the lowest frequency in the range and moves up the search range.
• In Max Hold Search mode, the scanner displays the strongest signal that it found.
• If you manually set the mode to NFM or FM, the scanner will not reliably detect signals that are modulated in either FMB or WFM.

To turn on Band Scope mode:

Band Scope mode is the default setting for Search Key 3. To turn on Band Scope mode, enter Search mode, then tap FUNCTION + 3 (SR3) . (To change the Search Key assignment, see Search Keys#Programming Search Keys.)

Changing Band Scope Parameters

To change between band scope search and band search max hold modes, press F+SCAN.

You can adjust the span, center frequency, and step size used in Band Scope mode. To make an adjustment, press ./no one time. The setting being adjusted flashes. Repeatedly press ./no until the setting you want to adjust is flashing.

• CF -- Center Frequency. While CF is flashing, press E/yes then enter the desired center frequency.

• SPN -- Span. While SPN is flashing, rotate the scroll knob to select the desired frequency span. You can select from:

  • 0.2MHz, 0.4MHz, 0.6MHz, 0.8MHz, 1MHz, 2MHz, 4MHz, 6MHz, 8MHz, 10MHz, 20MHz, 40MHz, 60MHz, 80MHz, 100MHz, 120MHz, 140MHz, 160MHz, 180MHz, 200MHz, 250MHz, 300MHz, 350MHz, 400MHz, 450MHz, and 500MHz
