Product Usage Instructions
The Twilight Switch LED Lamp Educational Soldering Kit is intended for
educational and demonstration purposes only. It should not be used in
commercial applications or as a part of life support systems. The user assumes
all responsibility for ensuring compliance with all local laws.
When assembling the kit, it is essential to follow the suggested order of
assembly provided in the manual. Begin by soldering the elements onto the
circuit board in order from smallest to largest. When soldering the elements
marked with the “!” symbol, pay attention to their polarity and placing of the
notch. The frames with symbols of these elements on the circuit board, as well
as photos of the assembled kit, can be helpful.It is important to check your
work carefully and ensure that all components are placed in the correct
locations and orientation. Failures in modern electronic components are rare,
and most non-working kits are due to poor soldering or misplaced components.
The manufacturer reserves the right to make changes without prior notice.
Assembly and connection of the device not in accordance with the instructions,
unauthorized modification of components or structural modifications may cause
damage to the device and endanger the person using it. In this case, the
manufacturer and its authorized representatives shall not be liable for any
damages arising directly or indirectly from the use or malfunction of the
product.
After usage, do not dispose of the product with other household waste.
Instead, hand it over to a designated collection point for the recycling of
waste electrical and electronic equipment.

Begin by soldering the elements onto the circuit board in order from smallest
to largest.
When assembling the elements marked with “!” pay attention to their polarity
and placing of the notch.
You may find the frames with symbols of these elements on the circuit board,
as well as photos of the assembled kit helpful.
Assembly instructions
- Touch the tip of the soldering iron to the end of the element near the soldering field
- Next, apply tin solder
- After the cone forms, remove tin solder first, and then the soldering iron
- The whole process should take approx. 2-3 seconds.
The cleanness of the soldered surfaces, right amount of flux in the solder,
adequately high temperature (320-360°C), and sufficient amount of solder are
necessary to complete a correct bonding.
Too much tin solder can result in forming a ball instead of a cone or joining
of two adjacent soldering points.
Inadequate temperature, amount of tin solder or impurities can lead to so
called “cold solder joints, i.e. solder and the flux can’t moisten the two
surfaces and the resulting solder point is fragile and in time will oxidize,
break, and stop working.
Thank you for purchasing AVT product. Please take your time to read carefully
the important information below concering use of this product.
Educational Electronics Kits are intended for educational and demonstration
purposes only. They are not intended for use in commercial applications. If
they are used in such applications the purchaser assumes all responsibility
for ensuring compliance with all local laws. In addition, they cannot be used
as a part of life support systems, or systems that for use as or as a part of
life support systems, or systems that might create a hazardous situation of
any kind.
- Battery or wall-adaptor are safe devices. They do not require special attention unless main voltage is connected to an output e.g. a relay.
- If the kit is used to switch currents greater than 24V it is necessary to have the installation and performed by a trained professional authorized for such work. The kit may only be used in such application if it was installed in a safe to touch enclosure.
- Never exceed the limits or ratings listed in the ‘Specifications’ section at the this user guide.
- If the kit is used in schools or educational facilities or similar institutions the operation must be supervised by trained and authorized staff.
- The product itself and all parts thereof (including packing material) are not suitable toys for childern! (choking hazard, risk of electric shock, …)
Failures in modern electronic component are very rare as 95% of non-working kits are due to poor soldering or components placed in the wrong location or orientation so please check your work carefully.
