Product Overview

This user manual provides instructions for the TECKNET Wireless Doorbell system, including the push button transmitter and receiver.

Product Layout

The system consists of a Push Button/Transmitter and a Receiver.

• Push Button/Transmitter: The device that is pressed to activate the doorbell.
• Receiver: The unit that chimes when the push button is pressed.

Controls:

• ⚙️Setup Button: Used to select operating modes (Flashing Only, Ringing Only, Flashing & Ringing).
• ?Music Button: Used to select chime melodies and for pairing.
• ?Volume Adjustment: Used to select one of four volume levels.

For Home Installation Scenarios

Please read the following precautions carefully:

• Ensure there is no interference from wireless radio devices of the same frequency (433MHz) within the range of use.
• DO NOT install the transmitter on metal doors, windows, surfaces, or semi-closed metal frames, as this will severely reduce the transmission distance.
• The receiver should be installed as far away as possible from metal objects, household appliances, or other electrical equipment, as electromagnetic interference can affect the wireless signal.
• Avoid obstacles between the transmitter and receiver as much as possible. Install the receiver as close as possible to the direction of the transmitter.
• The wireless signal strength of the doorbell can vary from strong to weak in houses made of plank, brick, and concrete.

How to Use

1. ⚙️Select a Working Mode: Press the setup button to choose from 3 working modes: Flashing Only, Ringing Only, and Flashing & Ringing.
2. ?Select a Chime: Press the music button once to play the next chime and select the one you like. Press the button twice to go back to the previous chime.
3. ?Select a Volume Level: Press the volume button to choose from 4 volume levels.

Pair Push Button to Receiver

Transmitter Installation

1. Remove the battery isolation strip on the back of the transmitter before use.
2. Use the enclosed double-sided adhesive tape to stick the transmitter to the wall or door.

[Diagram Description: The diagram shows three steps: 1. A hand pulling a small plastic strip from the back of the transmitter. 2. A piece of double-sided tape being applied to the back of the transmitter. 3. The transmitter being mounted on a wall or door frame.]

Troubleshooting

If the transmitter doesn't light up when pressed:

• Check if the transmitter battery is low. If the indicator keeps flashing or does not light up at all, replace the battery.

If the receiver doesn't respond or light up after connecting to power:

• Check the connected power socket for electricity (or try a different power socket).

If pressing the transmitter results in it lighting up, but the receiver doesn't light up or ring:

• Verify if the receiver is properly powered as mentioned in the second point.
• Check if the remote distance exceeds the range. Bring the transmitter and receiver closer to eliminate signal interference.
• Clear the pairing records and re-pair the transmitter with the receiver.
• It is recommended to install the transmitter and receiver at a height of at least 1 meter from the ground for optimal performance.
• Place the receiver away from other electrical devices (such as refrigerators, fans, televisions, induction cookers, etc.).
• If the installation location of the transmitter is made of metal, aluminum, iron, or marble, the remote distance may be significantly reduced.
• If you encounter this issue when pairing multiple receivers/transmitters, verify if the wireless doorbell transmission systems are compatible. The amplitude modulation OOK system is not compatible with the frequency modulation FSK system. For more details, please consult customer service.

If the transmitter lights up and the receiver lights up but doesn't ring or produces a very low sound:

• Check if the receiver is in silent mode by pressing the setup button ⚙️. (Working modes include: Flashing only/Silent mode; Ringing only; and Flashing & Ringing).
• Adjust the ring volume to a comfortable level using the volume button ?.

If one of the receivers doesn't work:

• Keep a distance of at least 1 meter between the receivers. Plugging the receivers into the same power strip may affect signal reception, resulting in only one receiver ringing.

If the receiver automatically rings without pressing the transmitter:

• Verify if there was a power outage followed by power restoration in your house. If yes, the automatic ringing is normal in such a case.
• Check if the receiver is properly plugged into the power socket.
• If the doorbell frequently rings by itself every day, please contact customer service for assistance.

If the double-sided adhesive tape doesn't stick:

• Ensure that the installation surface is clean, dust-free, and flat.
