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 o r c loth , to ke ep it c lean ; th en apply so lder to th e t ip, to g ive it a wet look. This is called ‘thinn ing’ an d w ill
protect the tip, an d enab les you t o make good conn ections. When so lder ro lls of f th e tip, it ne eds clean ing.
• Thin raisin-core solder. Do not use any flux or grease.
• A diagonal cutter to trim excess wires. To avoid in jury wh en cutting ex cess leads, ho ld the lead so th ey
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 poss ible last m inu te manu al updates, indicated as ‘NOTE ’ on a separate leaflet.

Personal code
17. Create your code
You can select your own code for a transmitter/receiver combination. There is a 9 row jumper island located directly
next to IC1 for setting the code. The code is set by connecting one or more code poin ts to a neighboring ‘+’ or ‘-‘ point
using the small jumpers. Code points may also be left unconnected (open): see figure.
: certain points cannot be connected to ‘+’

Operating mode
18. Operating mode
By using the jumpers JM1 or JT1, channel 1 of the receiver can be set up for two output possibilities:
1. Output channel 1 is o n w hile t he transmit ter i s pre ssed (MOM EN T), thi s is mo stly u sed for opera ting a do or lock,
garage door, etc.
JM1
2. Output channel 1 switches (on/off) every time the transmitter is pres sed (TOGGLE), this setting is mo stly used for
switching alarms in and out , for operati ng cen tral door lo cking syste ms, for sw itching a la mp on and off, e tc.
JT1
By using the jumpers JM2 or JT2, channel 2 from the receiver can be set up for two output possibilities:
1. Output channel 2 i s on w hile the t ransmitter is pr e ssed (MOM ENT).
JM2
2. Output channel 2 switches (on/off) every time the transmitter i s pressed (TOGGLE).

Test & set-up
19. Test and set-up
IMPORTANT:
• For adj usting the receiver, a com pletely plastic tuning sc rewdriver (including plas tic blade) is needed. This is
supplied with the receiver.
• The t ransm itt er must be in its housing with the c over on, and fi tt ed with a ne w battery t ype V23GA or GP 23A.
Check the polarity which is shown in the housing.
• The receiver may not be in the vicinity of any metal objects.
• The transmitter and receiver must have the same code.
1) Use of the new K6706A transmitter:
• Set the tuning capacitor CV1 of the receiver to around the middle of its adjustment range (see fig. 7).
Check that the tuning LED of the receiver is not lit up, or is just on the verge of lighting up. If not, the tuning
capacitor will have to be adjus ted a little. Do not touch the circuit with your hand.
• Activate the transmitter and very carefully turn the tuning capacitor CV1 on the receiver until the tuning LED
lights up. If all is well, one of the relays should now switch, if of course the codes of the transmitter and receiver
are the same.
• For more precise tuning, get someone else to activate the transmitter from a few meters away and then finetune the receiver.
• Once the re ceiv er has be en set to a tra n smitt er, the n it will a lso be se t fo r oth er tran smi tte rs of the K670 6A ty pe .
2) Use of the old K6706 transmitter:
• Remove capacitor C1 from the transmitter.
• Set the tuning capacitor CV1 of the receiver to around the middle of its adjustment range (see fig. 7).
Check that the tuning LED of the receiver is not lit up, or is just on the verge of lighting up. If not, the tuning
capacitor will have to be adjusted a little. Do not touch the circuit with your hand.

Test & set-up
• The transmitter must be in its housing with the cover off.
• Activate the transmitter (do not touch any other parts other than the push button) and then very carefully turn
the tuning capacitor CV on the transm itter unt il the tuning LED of the recei ver lights up. I f all is well, one of
the relays should now switch, if of course the codes of the transmitter and receiver are the same.
• For more precise tuning, activate the transmitter from a few meters away and then fine-tune the transmitter.
If the transmitter cannot be tuned to the receiver, then it might be that the tuning capacitor of the
receiver needs to be adjusted.
3) Use of a new K6706A transmitter together with an old K6706 transmitter:
• Do the receiver set-up and adjustment as in point 1 together with the new transmitter type K6706A.
• When using the old K6706 transmitter type, capacitor C1 of the transmitter must be removed.
• The transmitter must be in its housing with the cover off.
• Activate the transmitter (do not touch any other parts other than the push button) and then very carefully turn
the tuning capacitor CV on the transm itter unt il the tuning LED of the recei ver lights up. I f all is well, one of
the relays should now switch, if of course the codes of the transmitter and receiver are the same.
• For more precise tuning, activate the transmitter from a few meters away and then fine-tune the transmitter.
REMARK: When a new receiver K6727 is used in conjunction with a one channel receiver K6707, then on
the K6707 capacitor C1 must be a 1pF type.

DO NOT ADJUST THIS RECEIVER
From one receiver, the jumpers J1 and J2 must be cut, this receiver must not be adjusted with the transmitter.
22. About the housing
The circuit can also be installed in a plastic housing (NOT A METAL BOX) e.g. WCAH2851.
Place the housing in a pl ace where there are few metal parts. It may be the case that after installation, the circuit
will have to be retuned. This is because of the influence of metal parts in the vicinity of the circuit.
