Solight 1L73 Wireless Doorbell User Manual

Quick guide from the manual

The Solight 1L73 is a wireless doorbell system with a range of up to 200m in open space. The receiver can be powered by 3x AAA batteries or via a USB-C cable. The transmitter is waterproof and battery-operated (CR2032). The system supports pairing multiple transmitters and receivers.

Receiver setup

The receiver can be powered in two ways:

• Battery operation: Open the battery cover and insert 3x AAA alkaline 1.5V batteries, observing the correct polarity.
• USB powered operation: Connect a USB adapter to the mains and plug the USB-C cable into the receiver. Important: If batteries are installed, remove them before using USB power to prevent damage.

The receiver can be placed on a surface or hung using the mounting holes. Do not cover the speaker.

Transmitter installation

Before mounting, test the wireless connection in the desired location. The transmitter is waterproof and suitable for outdoor use, but avoid areas with excessive heat or water exposure.

• Attach the installation pad to the base using double-sided adhesive tape or screws with dowels.
• Fit the transmitter with the tabs on the back into the holes of the installation pad and push to the side to secure it.
• Warning: Do not place the transmitter directly on metal objects or materials containing metal (e.g., steel posts, metal-framed doors), as this may interfere with the signal.

Pairing and deleting transmitters

Pairing:

1. Insert batteries into the receiver or connect it to USB power.
2. Long press the pairing button on the receiver for approximately 5 seconds.
