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 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 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 !

1. Connect the telephone connections ‘A’ and ‘B’ to the
telephone line connections ‘a’ and ‘b’.
2. Connect a transformer or adapter of 12VAC min. 300mA to
the AC connections.
3. If required, connect the switching outputs to the devices.
The three outputs between L and P are normally open
contacts
4. If you want to check the condition of a (dead) switch, it may
be connected between the SW terminals. If the switch is
closed, the green IN LED will light up.

1. The three outputs may be turned on or off manually by means of the push button. If the output is on
(contact closed) the corresponding LED will light up.
2. Press the push button once to turn output 1 on or off.
3. Press the push button twice shortly after one another to turn output 2 on or off.
4. Press the push button three times shortly after one another to turn output 3 on or off.

Normally the device is set to pick up the phone after ± 8 rings. If, however, you would like the device to pick
up the phone sooner (after ± 3 rings), the manual operating push button should be held pressed before
switching on the power supply. Output 1 will switch on by way of confirmation.

ESTABLISHING THE CONNECTION:
1. Call the phone number to which the remote control is connected.
2. After about 3 or 8 rings the remote control will answer. The red "ON LINE" LED on the device will flash.
3. A few seconds after picking up you will hear the condition of the outputs. First de switch input, then output
1, output 2, and output 3 in that order. A double tone indicates that the condition is ON, whereas a single
tone indicates that the condition is OFF.
RETRIEVING INFORMATION FROM OUTPUTS OR INPUT:
Enter: code1, code2 and then 0 0. Now you will once again hear the condition of the input and of the outputs.
This procedure may be repeated as often as you like.
SWITCHING A PARTICULAR OUTPUT ON:
Enter: code1, code2, output number, 1. After a few seconds you will hear the condition of the input and of the
outputs.
Example: Suppose you want to switch output 2 on and that your code is 43. Enter the following digits: 4-3-2-1.
SWITCHING A PARTICULAR OUTPUT OFF:
Enter: code1, code2, output number, 0. The condition of the input and of the outputs will be repeated
immediately.
Example: Suppose you want to switch output 2 off and that your code is 43. Enter the following digits: 4-3-2-0.
 NOTES:
 If you do not press a button within 20 seconds, the connec-tion will be terminated automatically.
 If you enter a wrong code, you will hear an alarm tone. After that, you still have two chances to enter the correct
code. If the correct code has not been entered after three attempts, the device will terminate the connection.

28. Mounting into a housing (Optional)
The entire circuit may be built into a plastic housing (e.g. our housing type D30), which will allow the LEDs
and the push button to protrude through the front panel (see figure for boreholes and board position). After
cutting out the LED frame, the included sticker may be attached to the front panel.
