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

of the element near the soldering field

Too much tin solder can result in forming a ball

instead of a cone or joining of two adjacent

soldering points.

seconds.

The whole process should take approx. 2-3

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.

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.

Touch the tip of the soldering iron to the end

Next, apply tin solder

After the cone forms, remove tin solder first,

and then the soldering iron

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.

Thank you for purchasing AVT product. Please take your time to read carefully the important information below concering use of this

product.

• Never exceed the limits or ratings listed in the 'Specifications' section at the this user guide.

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.

• The product itself and all parts thereof (including packing material) are not suitable toys for childern! (choking hazard, risk of electric

shock, ...)

• 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.

• 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 in schools or educational facilities or similar institutions the operation must be supervised by trained and authorized

staff.
