  • Page 35: Scanning

    With this scan mode, scanning is carried out with the steps set in VFO mode. If all the bands that can possibly be received were to be scanned, the scanning time would be too long so with the DX-R8T/E, amateur bands are categorized as separate, and scanning is conducted by scanning inside and outside of the amateur bands which makes it easier to nd the frequency band's wave.
  • Page 36 PS0633 DX-R8T/E 4. Scanning Programmed scan This function scans an user-speci ed range of frequencies. Before using this function, you need to specify the upper and lower frequency limits for programmed-scanning.
