- Main ON/OFF Switch: Powers the device on or off.
- Timer Mode Selector: Allows selection of operating modes (DUSK 4HRS, DUSK 7HRS, OFF, ON).
- Light Sensor: Detects ambient light levels for automatic dusk activation (integrated).
5. Setup
5.1 Mounting the Device
Choose an appropriate indoor location for the TV simulator. For optimal effect, place it near a window where the light can be visible from outside, mimicking a TV in a living room or bedroom. Ensure the light sensor is not obstructed.
- Mark the desired mounting position on the wall.
- Drill two holes at the marked positions, suitable for the provided wall plugs.
- Insert the wall plugs into the drilled holes.
- Align the mounting holes on the base of the TV simulator with the wall plugs.
- Secure the device using the provided screws.

5.2 Power Connection
Connect the small end of the USB power cable to the USB power input on the back of the TV simulator. Connect the larger USB-A end to a 5V/1A USB power adapter (not included) and plug the adapter into a wall outlet.
6. Operating Instructions
The Nedis TV Simulator offers several operating modes:
- Power On: Flip the main ON/OFF switch to the 'ON' position.
- Select Operating Mode: Use the timer mode selector switch to choose your desired setting:
- DUSK 4HRS: The device will automatically turn on at dusk (when ambient light falls below a certain level) and operate for approximately 4 hours.
- DUSK 7HRS: The device will automatically turn on at dusk and operate for approximately 7 hours.
- ON: The device will remain continuously on, regardless of ambient light. This mode is generally not recommended for security simulation as it does not mimic natural TV usage patterns.
- OFF: The device will remain off.
- Realistic TV Effect: Once activated, the simulator will emit random sequences of multicolour light, varying in intensity and hue, to create a convincing impression of a television being watched.
7. Maintenance
- Cleaning: To clean the device, gently wipe its surface with a soft, dry cloth. Do not use liquid cleaners, abrasive materials, or chemical solvents, as these may damage the unit.
- Storage: If the device is not in use for an extended period, disconnect it from the power source and store it in a cool, dry place, away from direct sunlight and moisture.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on. | No power, incorrect power adapter, main switch is OFF. | Ensure USB cable is securely connected. Verify power adapter is working and provides 5V/1A. Check that the main ON/OFF switch is in the 'ON' position. |
| Lights do not activate at dusk. | Incorrect timer setting, light sensor obstructed, room not dark enough. | Set the timer mode selector to 'DUSK 4HRS' or 'DUSK 7HRS'. Ensure the light sensor is clear of obstructions. Wait for the room to become sufficiently dark for the sensor to activate. |
| Lights are too bright/dim or not changing. | This is normal operation. | The device is designed to emit varying light patterns and intensities to simulate a TV. There are no adjustable brightness settings. |
