Use fuses of the same specified rating (15A). Using different
substitutes or fuses with higher ratings, or connecting the
product directly without a fuse, could cause fire or damage to
the stereo unit.
4 MAINTENANCE
Your products is designed and manufactured to ensure a
minimum of maintenance. Use a dry, a soft cloth for routine
exterior cleaning. Never use benzine, thinner or other solvents.
