Overview

The COMMAX CDV-43K is a color video door phone designed for smart home and security applications. It serves as a communication and monitoring device, allowing users to interact with visitors at their entrance and manage door access.

Function Description:

The primary function of the CDV-43K is to provide visual and audio communication with visitors. When a visitor presses the call button on the door camera, the monitor displays the visitor's image, and a chime sounds. The user can then initiate a two-way conversation with the visitor. The device also supports door release, allowing the user to remotely unlock the door for the visitor. This door release function is active only when the visitor's image is displayed on the screen, ensuring security.

Beyond visitor interaction, the CDV-43K offers a monitoring function, enabling users to view the entrance area at any time, even in standby mode. This is achieved by repeatedly pressing the "Monitor" button, which cycles through "Camera," "OFF," and "Camera" modes.

The system can be expanded with an optional interphone, facilitating communication between the main monitor and the interphone unit. When a visitor calls, both the monitor and interphone ring simultaneously, allowing either unit to pick up the call and engage in a three-way conversation (monitor, interphone, and visitor). Communication between the interphone and the camera is possible only when the visitor's image is visible on the monitor screen.

Usage Features:

The CDV-43K offers several user-adjustable settings to customize the viewing experience and audio levels. These settings are accessed via the "Menu" button on the front of the product, either in video talk mode or standby monitoring.

  • Screen Settings (Brightness/Contrast/Color Adjustment): Users can adjust the brightness, contrast, and color of the screen. This is done by navigating to the "DOOR VIDEO SET" menu, selecting the desired parameter (Brightness, Contrast, or Color), and then using the up/down buttons to adjust the value. The "SELECT" button confirms the setting.

Maintenance Features:

The manual emphasizes several safety and maintenance guidelines to ensure the longevity and proper functioning of the CDV-43K:

  • Installation Environment:
    • Avoid installing the product in areas with direct sunlight, excessive oil, smoke, humidity, or near lightning and thunder.
    • For heat-generating products, ensure a minimum 10cm clearance from walls for ventilation.
    • The recommended installation height for the monitor is 1450 ~ 1500mm.
    • Do not install the door camera in direct sunlight or backlight.
  • Power Management:
    • Do not use multiple products on a single power socket to prevent overheating and fire.
    • Avoid bending the power cable excessively or using damaged power cables, as this can cause electric shock or fire.
    • Do not handle the power cable with wet hands.
    • Unplug the power cable from the socket when not in use for extended periods to prolong product lifespan and prevent fire.
    • Ensure all electric power is blocked by the building blocking device when installing or repairing the product.
    • The plug serves as a disconnection device and should remain readily accessible.
  • Cleaning:
    • When cleaning the product, use a soft, dry cloth. Do not use chemical products like benzene or alcohol.
    • Keep the door camera lens clean for clear image reflection.
  • General Precautions:
    • Do not disassemble, repair, or rebuild the product. Contact a service center if repairs are needed.
    • Do not insert any metallic or flammable materials into the product.
    • Do not use the product with other devices that have different rated voltages.
    • Do not place water bottles or flowerpots on the product.
    • The apparatus should not be exposed to dripping or splashing liquids, and no liquid-filled objects (like vases) should be placed on it.
    • In case of physical damage or operational failure, contact the Service Center immediately.
    • Do not hold the handset to your ear when pressing the hook switch to switch calls.
