Setup and Installation

- Three Plastic Adapters (for various door thicknesses)

Required Tools (Not Included):

Installation Steps:
- Remove Existing Peephole (if applicable): If a traditional peephole is present, carefully unscrew and remove it from the door.
- Prepare the Door Hole: Ensure the door hole is clean and has a diameter suitable for the lens unit. If a new hole is required, use a 14 mm drill bit. For the transmission cable, a 3 mm drill bit might be needed if a separate hole is not already present or if the main hole is too tight.
- Insert Lens Unit: From the exterior side of the door, insert the lens unit through the prepared hole. Ensure the camera is facing outwards and is correctly oriented. The transmission cable should pass through to the interior side.
- Attach Mounting Fork: On the interior side, slide the mounting fork over the transmission cable and secure it to the lens unit.
- Install Plastic Adapters: Select the appropriate plastic adapter(s) based on your door's thickness (38 mm to 110 mm). Place them between the mounting fork and the door surface to ensure a snug fit.
- Connect Screen Unit: Connect the transmission cable from the lens unit to the designated port on the TFT screen unit.
- Mount Screen Unit: Secure the TFT screen unit to the mounting bracket. The bracket should be attached to the interior side of the door, aligning with the lens unit. Use a Phillips screwdriver to tighten any screws.
- Insert Batteries: Open the battery compartment on the screen unit and insert the four AAA alkaline batteries, observing correct polarity.
- Test Functionality: Press the 'ON' button on the screen unit to verify that the digital door viewer is functioning correctly and displays an image from the exterior.

Operating Instructions
Using the ABUS DTS2814 Digital Door Viewer is straightforward:
- Power On: Locate the 'ON' button (usually on the side or front of the screen unit). Press this button to activate the display.

- Automatic Shut-off: To conserve battery life, the screen will automatically turn off after a short period of inactivity.
The large, clear display is particularly beneficial for individuals who may find traditional peepholes difficult to use, such as children, seniors, glasses wearers, or those with mobility challenges.
