Usage Features
The manual highlights several usage features, particularly concerning the remote control unit and on-screen display (OSD) for adjustments and settings.
- Remote Control Unit: The remote control unit (AXD1468) is essential for accessing and navigating the monitor's menu system, including setup, program blocking, and various adjustments. It features dedicated buttons for power, input selection, screen mode, display, channel selection, volume, muting, and menu navigation.
- Menu System: The monitor's menu system allows users to configure various settings, such as picture quality (color, tint, contrast, brightness, sharpness), sound (bass, treble, balance, surround), and system settings (time, screen mode, CC, RLS).
- Program Blocking (V. Chip): The V. Chip function allows users to block undesirable programming based on MPAA and Canadian rating systems. This feature can be configured via the setup menu, requiring a password for access and changes.
- Multi-Screen Function: The monitor supports multi-screen viewing modes, including SPLIT screen (two vertically split images) and FREEZE screen (freezing one image while another continues). These modes are accessible via dedicated buttons on the remote control.
- Searching for Programs (SEARCH screen): The SEARCH screen mode allows users to view multiple images (nine or four) simultaneously, facilitating program searching.
- Power Management: The monitor automatically enters power management mode if no digital signal is input when digital input is selected, conserving power. The POWER STANDBY indicator (green) flashes during this mode.
- Input Selection: The monitor provides multiple input terminals, and users can switch between different sources using the INPUT SELECT button on the remote control or front panel.
