Pairing the Supplementary Camera
The DVM-75C camera needs to be paired with your DVM-73 parent unit. The DVM-73 system supports up to four cameras.
- Place the DVM-75C camera in the desired location, ensuring it has a clear view of the area you wish to monitor.
- Connect the power adapter to the DVM-75C camera and plug it into a power outlet. The power indicator light on the camera will illuminate.
- Ensure your DVM-73 parent unit is turned on and within range of the camera.
- On the DVM-75C camera, locate the PAIR button.
- On the DVM-73 parent unit, navigate to the camera pairing menu (refer to your DVM-73 manual for specific steps, usually found under 'Camera Settings' or 'Add Camera').
- While the parent unit is in pairing mode, press and hold the PAIR button on the DVM-75C camera for approximately 3 seconds until the camera's power indicator starts flashing.
- The parent unit should detect and pair with the new camera. Once successfully paired, the power indicator on the camera will stop flashing and remain solid, and the image from the new camera will appear on the parent unit's screen.
If pairing fails, ensure both units are close to each other and repeat the steps. You may need to reset the camera or parent unit if issues persist.

Operating Instructions
Once paired, the DVM-75C camera operates in conjunction with your DVM-73 parent unit. All primary controls are managed via the parent unit.
Camera Features
- Night Vision: The camera automatically activates infrared LEDs in low-light conditions, providing a clear black-and-white image of your baby, even in complete darkness.
- Two-Way Talk-Back: Use the microphone on your parent unit to speak to your baby through the camera's built-in speaker. This feature allows you to soothe your baby from another room.
- Digital Zoom: The parent unit allows you to digitally zoom in on the camera's image for a closer view of your baby.
- Adjustable Angle: The camera unit can be manually tilted and swiveled on its stand to achieve the optimal viewing angle.

Switching Between Cameras (Multi-Camera Setup)

- Manual Switching: On the parent unit, use the designated camera selection buttons or menu options to manually switch between the paired cameras.
- Scan Mode: Activate the scan mode on the parent unit. The unit will automatically cycle through all paired cameras, displaying each camera's feed for a few seconds before moving to the next.
