cles), use the power supply or aerial connec-
tions intended for use with the basic wiring.
Be sure to observe the manufacturer's addi-
tional instructions when installing the fittings.
! Have aftermarket radio frequency trans-
mitting equipment installed at a qualified
specialist workshop. Mercedes-Benz rec-

sions relating to the possible health hazards
that may result from electromagnetic fields.
