  • Page 23: Configuration

    3.1 SPC - Channel Spacing With this setting, the ATR833A can be configured to constrain frequency selection to 25 kHz channels only. This can be used to speed up the manual frequency input in areas where no 8.33 kHz channel spacing is used.

  • Page 24: Energy Saving Mode - Automatic Display Darkening

    This configuration item is not used for selection of 8.33 kHz or 25 kHz use of a specific frequency, as this is done by the ATR833A automatically depending onto the frequency value entered. The interested user may refer to chapter 5 for information about which frequency values correspond to which channel widths.
