higher. Please use a soldering iron with temperature control
and adjust it to 700 ± 20
°
F (370 ± 10
°

high temperature soldering iron, please be careful not to

1.3. Replacing the Fuse
Use fuses of the same specified rating 15 amps. Using different
substitutes or fuses with higher ratings, or connecting the unit
directly without a fuse, could cause fire or damage to the stereo
unit.

Your product is designed and manufactured to ensure a mini-
mum of maintenance. Use a dry, a soft cloth for routine exterior
cleaning. Never use benzine, thinner or other solvents.
