Setup Instructions
1. Receiver Installation
- Select a suitable indoor EU wall socket for the receiver. Ensure it is within the desired range of the transmitter.
- Plug the receiver directly into the chosen wall socket. The integrated socket on the receiver allows you to continue using the power outlet for other devices.
2. Transmitter Installation
Choose a location for the transmitter (push button unit) outside your door. Consider factors like direct sunlight, rain exposure, and ease of access for visitors. The transmitter is IP65 waterproof, but placing it under a small overhang can offer additional protection.

There are two primary methods for mounting the transmitter:
- Using Double-Sided Adhesive Tape:
- Clean the mounting surface thoroughly to ensure it is dry and free of dust or grease.
- Peel off one side of the protective film from the double-sided adhesive tape and attach it to the back of the transmitter.
- Peel off the other side of the protective film and firmly press the transmitter onto the desired surface for at least 30 seconds.
- Using Screws and Anchors:
- Mark the desired drilling points on the wall using the transmitter as a template.
- Drill two holes at the marked positions.
- Insert the plastic anchors into the drilled holes.
- Align the transmitter with the holes and secure it with the provided screws.
The transmitter and receiver are pre-paired at the factory. If re-pairing is ever needed, refer to the troubleshooting section.
Operating Instructions
1. Changing Ringtones
To change the ringtone, locate the 'Music Selection' button on the side of the receiver. Press this button repeatedly to cycle through the 32 available melodies. The receiver will play each melody as you press the button. Once you hear your preferred melody, stop pressing the button, and it will be set.
2. Adjusting Volume
To adjust the volume, locate the 'Volume Control' button on the side of the receiver. Press this button to cycle through the 5 available volume levels (ranging from 25 dB to 90 dB). Select the volume level that best suits your needs.
3. LED Indicator

Maintenance
To ensure the optimal performance and longevity of your TECKNET Wireless Doorbell, follow these simple maintenance guidelines:
- Cleaning: Wipe both the transmitter and receiver with a soft, dry cloth. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the surfaces.
- Transmitter Placement: Periodically check the transmitter's mounting to ensure it remains securely attached to the surface. If using adhesive tape, ensure the surface is still clean and dry.
- No Battery Replacement: The transmitter is self-powered, so no battery replacement is ever required.
- Environmental Conditions: While the transmitter is waterproof (IP65), extreme temperatures or prolonged exposure to direct harsh weather conditions (e.g., blizzards, intense heat waves) should be minimized if possible to extend its lifespan.
Troubleshooting
If you encounter any issues with your TECKNET Wireless Doorbell, please refer to the following common problems and solutions:

Re-pair the units (see below). |
| Short wireless range. | Thick walls or metal structures. Interference from other devices. Receiver placed too low. | Relocate receiver or transmitter to minimize obstructions. Move doorbell away from other wireless devices (e.g., Wi-Fi routers, microwaves). Place receiver higher on a wall. |
| False ringing. | Interference from other wireless devices. | The digital code system minimizes this, but if it occurs, try re-pairing the units to reset the code. |
