1. Assembly (Skipping this can lead to troubles ! )
Ok, so we have your attention. These hints will help you to make this project success-
ful. 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 en-
ables 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 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 :
Mount the component against the PCB surface and carefully solder the
leads
Make sure the solder joints are cone-shaped and shiny
Trim excess leads as close as possible to the solder joint
REMOVE THEM FROM THE TAPE

Your own individual code can be set for a transmitter/receiver combina-
tion. There is a row of nine code pads that are the closest to IC1. The
code can be set by linking one or more code pads to a neighbouring "-"
pad or "+" pad by using a jumper lead.
Note: two code connections cannot be connected to the "+" line, this
is normal

IMPORTANT:
•Before mounting the PCB into the enclosure, be sure to
trim all the leads !
•Bend C6 like in the drawing:
•For adjusting the receiver, a completely plastic tuning
screwdriver is needed. This is supplied with the receiver.
•The transmitter must be in its housing with cover on, and
fitted with a new battery type V23GA or GP23A. Check the
polarity which is shown in the enclosure.
•The receiver may not be in the vicinity of a metal object.
•The transmitter and receiver must have the same code.
•On the receiver K6707, either jumper lead CH1 has to be
mounted in order to be operated by button SW1 (big) of the
transmitter, or jumper lead CH2 has to be mounted for op-
eration by button SW2 (small).

1) Use of the new transmitter with the K6707 receiver or
car alarm type K3511
•Replace C1 on the receiver with a 1pF capacitor. This
capacitor is supplied with the transmitter.
•Set the tuning capacitor of the receiver to around its mid
position (see fig. 17 in the receiver handbook). Check
that the tuning LED of the receiver is not lit or is only
just lit up, if not set the capacitor slightly differently. Do
not touch the circuit with your hand.
•Activate the transmitter and turn the tuning capacitor on
the receiver until the receiver tuning LED lights up. If all
is well, the relay should switch if the transmitter and
receiver codes are the same.
•For more precise tuning, get someone else to activate
the transmitter from a few metres away and then fine-
tune the receiver.
Once the receiver has been set to a transmitter, then it will
also be set for other transmitters of the new type.
