If the indicator lamp now is flashing yellow, then
the break is somewhere in the wire between the
disconnected end to the point where the new wire
is connected (thick black line below). In that case,
move the connection for the new wire closer to the
disconnected end (roughly at the middle of the
suspected wire section) and check again if the
indicator lamp is green.
Continue until only a very short section of the wire
remains which is the difference between a solid

green light and a flashing blue light. Then follow
instruction in step 5 below.
4. If indicator lamp still flashes blue in step 3
above: Put L and GUIDE back in their original
positions. Then switch R and GUIDE. If indicator
lamp now is lit with a solid green light then
disconnect L and connect a new boundary wire to
L. Connect the other end of this new wire at the
middle of the suspected wire section. Follow the
same approach as in 3a) and 3b) above.
5. When the break is found, the damaged section
must be replaced with a new wire. Always use
original couplers.
