Construction
First the remote control PCB is assembled, P6706A:
The remote control can be build for wireless remote operation or for “wired” remote
operation (no need for battery in the transmitter). In case of a wired remote, only a few
components are mounted, see further.
Before mounting the components on the PCB, first check that the PCB fits in the
housing. Watch the small notch next to LD1. Should it not fit, then grind the edges of
the PCB carefully.
Mount only the components marked with “#” if wired remote is wanted.
