A) Fuse Replacement; B) Cleaning; Troubleshooting - Renkforce RSD-1802 Operating Instructions Manual

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.

12. Troubleshooting

The Renkforce RSD-1802 SD tuner you have purchased is equipped with state-of-the-art technology and
is safe to operate.
Nevertheless, problems or errors may occur.
Therefore, we would like to describe how to eliminate possible errors here:
Always observe the safety information!
No replay, no display, and the lights are out:
• Car fuse defective. Look up the respective fuse in the operation manual of your car. Check the fuse.
• The fuse of the SD tuner is defective. Remove the SD tuner and check the fuse.
• The positive line/earth line is loose. Remove the SD tuner and check the connections of the cables.
Replay only through one speaker:
• The balance control is wrongly adjusted. Adjust the balance control as described.
• The speaker connection has come loose. Remove the SD tuner and/or speakers and check the connec-
tions.
