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 often on 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 good connections. When solder rolls off 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 when cutting excess
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 :
leads,
⇒ 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 solderjoints are cone-shaped and shiny
3- Trim excess leads as close as possible to the solder joint
First : Bend the leads exactly like the drawing.

Next : Mount this LED like in the drawing (fig.
2.0). Solder one lead, check the position, if
necessary correct it by heating the soldering.
Last solder the second connection.
Bend the LED exactly like the drawing (fig.

Attention : Mount the transistor on the solder side!
Now bend the transistor towards the pcb, away from the IR & 3mm LED.

connections do not contact
any other parts of the
circuit.
9. Battery contacts
Solder a wire of 7cm (Ø 0,20mm)to the negative (-) connection of the PCB. The other end of
the wire will be soldered to the negative battery contact later on.

Mode selection & Use
12. Mode selection
At first power up, mode 1 is automatically selected.
Press and hold SHIFT to change mode. Led starts flashing.
Press button 1..8 to select desired mode as shown below.
Hint : When the batteries are inserted, the led flashes 1..4 times indicating the selected mode.
Key Description
1 'K6710 emulation with D4 mounted'- mode. Allows control of MK161/K8050/K6711/12/13.
15 channels available ('shift' & '8' = all clear). Shift is cleared after each key press.
2 'K6710 emulation with D6 mounted'-mode. Allows control of MK161/K8050/K6712/13. 15
channels available ('shift' & '8' = all clear). Shift is cleared after each key press.
3 'K6710 emulation with D5 mounted'-mode. Allows control of MK161/K8050/K6712/13. 15
channels available ('shift' & '8' = all clear). Shift is cleared after each key press.
4 Allows simultaneous control of K4100/K4500, MK163/MK164, MK161 and
K8050/K6711/12/13
5 Identical to 1 but ‘shift’ is not cleared after each key press.
6 Identical to 2 but ‘shift’ is not cleared after each key press.
7 Identical to 3 but ‘shift’ is not cleared after each key press.
8 Identical to 4 but ‘shift’ is not cleared after each key press.
13. Use
To access channel 1..8 :
Press button for channel 1..8.
Holding the button will result in continuous transmission, led will flash indicating transmission.
To access channel 9..16 :
Briefly press 'shift'. Led will light indicating that 'shift' has been pressed.
Press button 1..8 to access channel 9..16
Holding the button will result in continuous transmission.
If no button is pressed after 'shift' has been pressed, the 'shift'-led will turn off in about 10s, hereby
cancelling the 'shift'-selection.
Pressing 'shift' repeatedly toggles between shift-on and shift-off.
