Fuse Replacement; Cleaning; Troubleshooting - Renkforce RSD-1802 SD Mode D'emploi

a) Fuse Replacement
If it becomes necessary to replace a fuse, make sure that only fuses of the prescribed type and nominal
current are used (see "Technical Data").
Never repair fuses or bridge the fuse holder.
• When the power supply has been disconnected (disconnect ISO plug!) carefully remove the fuse from
the fuse holder next to the ISO plug.
• Replace it with a fuse of the same type.
• Only then can you reconnect the SD tuner to the electric on-board system and turn it on.
• Should the fuse trigger again, have the SD tuner repaired in a specialised workshop.
b) Cleaning
Clean the exterior of the device with a soft, dry cloth or brush only.
Never use any aggressive cleaning agents or chemical solutions that may damage the surface of the ca-
sing.
