3. dissipating capability of this unit is more than enough to provide uninterrupted operation However when full power is drawn in an already hot en vironment any loss in heat dissipating capability is likely to result in activating the thermal protection circuits The accessory fuse with holder to be connected on the red cord is a 20 ampere auto fuse When replacing the fuse be sure to use an identical 20 ampere amber auto fuse if your unit behaves abnormally turn it off immediately and consult an authorized Harman Kardon Service Station NSTALLATION LOCATIONS Installation Location N i The locations shown in the above illustration are recom mended for the CA240 installation If you prefer another lo cation consult an authorized Harman Kardon Dealer or Service Station before making the installation The recommended installation positions all result in verti cal orientation of the heatsink fins This provides the maxi mum heat dissipation capability If possible mount the CA240 chassis directly to a vertical or near vertical surface such as the inside wall behind the rear seat If this is not possible use the optional Vertical Mounting Bracket BR1 to mount the CA240 to a horizontal surface such as the trunk floor The brackets permit vertical heatsink orienta tion when mounting to a horizontal surface In addition to vertical orientation the recommended instal lation locations allow air to flow freely th
