Assembly hints
1. Assembly (Skipping this can lead to troubles ! )
Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully.
1.1 Make sure you have the right tools:
• A good quality soldering iron (25-40W) with a small tip.
• Wipe it oftenon a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called ‘thinning’ and will
protect the tip, and enables you to make goodconnections. When solderrollsoff the tip,it needs cleaning.
• Thin raisin-core solder. Do not use any flux or grease.
• A diagonal cutter to trim excess wires. To avoid injury whencutting excess leads, hold the lead so they
cannot fly towards the eyes.
• Needle nose pliers, for bending leads, or to hold components in place.
• Small blade and Phillips screwdrivers. A basic range is fine.
For some projects, a basic multi-meter is required, or might be handy
1.2 Assembly Hints :
⇒ Make sure the skill level matches your experience, to avoid disappointments.
⇒ Follow the instructions carefully. Read and understand the entire step before you perform each operation.
⇒ Perform the assembly in the correct order as stated in this manual
⇒ Position all parts on the PCB (Printed Circuit Board) as shown on the drawings.
⇒ Values on the circuit diagram are subject to changes.
⇒ Values in this assembly guide are correct*
⇒ Use the check-boxes to mark your progress.
⇒ Please read the included information on safety and customer service
* Typographical inaccuracies excluded. Always look for possible last minute manual updates, indicated as ‘NOTE’ on a separate leaflet.

1.3 Soldering Hints :
1- Mount the component against the PCB surface and carefully solder the leads
2- Make sure the solder joints are cone-shaped and shiny
3- Trim excess leads as close as possible to the solder joint
REMOVE THEM FROM THE TAPE ONE AT A TIME !
AXIAL COMPONENTS ARE TAPED IN THE COR-
RECT MOUNTING SEQUENCE !

7. Mounting the LED readout
1. Stick a piece of tape over the LED mounting holes. This allows
you to level the LEDs before soldering them.(see fig. 1.0).
Complete the assembly as follows :
2. Insert the LEDs BUT DO NOT SOLDER THEM YET!
Mind the polarity ! (fig 2.0)

3. Flip the PCB and guide all LEDs trough their holes (fig 3.0).
=> Make sure that all LEDs touch the tape!
4. Solder the connections (fig 4.0).
5. Remove the tape.

2 Holes must be drilled into the enclosure.
 Follow next steps exactly!
 Pay attention to the correct diameter.
Make sure the holes are free of burrs.
STEP 1
Drawing 5.0 provides a drill pattern for the ‘select’ button.
• Mark the centre of the hole with a pencil.
• Drill the hole using a 3.5mm drill.

Drawing 7.0 provides a drill pattern for the IR-LED.
• Close the enclosure with the 2 supplied screws. Mark the centre of the hole to be drilled on the top of the
enclosure (Fig 6.0). Make sure that the centre of the hole is in the middle of the housing and 7mm from
the left hand side (Fig 7.0)
• Drill the hole with a 5,5mm drill.
 Make sure the edges of the holes are completely smooth!

STEP 8
Before continuing, inspect your complete assembly once more !
Place two AAA-batteries in their support. (Fig 11).
If the batteries have been inserted correctly and no
assembly mistakes have been made, the LEDs will
show a brief animation, hereby indicating that the
unit is ready for use.

To operate a channel :
Press the ‘Transmit’- button.
The LED-readout will flash a # of LEDs in a bar-style according to the
selected channel as long as the button is pressed.
To change the current channel :
Press the ‘Select’- button repeatedly till the LED-display indicates the
desired channel :

The LED-display will turn off automatically if the unit has been left idle for a couple of seconds.
To clear all channels :
Press and hold the ‘Select’- button. The LED-readout will flash the upper and lower LED during the ‘clear’-
transmission.
To change the address :
Some Velleman IR kits feature address selection (such as the K8050 15 channel receiver), to increase the # of
available channels or to allow independent operation of different receivers in the same room.
• Press and hold the ‘Transmit’-button.
• Briefly press the ‘Select’-button.
The LED-display will indicate the selected channel by turning on the lower LEDs (adress 1), the middle LEDs
(adress 2) or the upper LEDs (adress 3).
• Press the ‘Select’-button repeatedly while holding the ‘Transmit’-button to
change the channel.
• Release both buttons to return to idle mode
