For tantalum capacitors please attend to the connection wire marked "+". This wire
has to correspond to the printed mark on the pc-board.
The resistor-networks are marked at one end for the assembly position with
“...103...” and additionally with a printed circle or a square. Assemble this component
that way that the marking corresponds with the marking at the first bore of the pc-
board. Additionally is the first bore marked with “1”.
Integrated circuits (IC) are either marked with a half round notch on one end or a
printed point for the correct mounting position. Push the IC`s into the correct socket
assuring that the notch or the printed point is corresponding to the half-rounded
marking on the pc-board. The IC2 has for identification the printed tag 24C256 or 2EB
1.
Please attend to the sensitivity of the ICs to electrostatic discharge, which will cause
immediate damage of the IC. Before touching those components please discharge
yourselves by contacting an earthed metal (e.g. earthed radiator) or work with an
electrostatic safety pad.
Assembly of the Light-DEC-Service PC-Board:
After placing all components onto the pc-board of the Light-DEC-Basic and the Light-
DEC-Service PC-board, the Light-DEC-Service will be assembled onto the Light-DEC-
Basic PC-board.
Firstly please tighten the two distance spacer to the basic pc-board with two of the four
cross section screws.
Apply now the Light-DEC-Service PC-Board into the socket bar-ST1 of the basic pc-
board. Pay attention that there is no offset of the Light-DEC-Service PC-Board to the
socket. The Light-DEC-Service PC-Board is in correct position at the socket bar ST1
of the basic pc board if you can screw the Light-DEC-Service PC Board to the distance
bolts.
The following picture 1 show the assembly procedure from the side view and the
picture 2 show the assembled unit with sight from the top.
