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 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 CORRECT MOUNTING SEQUENCE !

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.
