disconnect first device.
6. My radio does not enter CD changer mode. What can I do to fix this?
Check fuse on yellow wire. If fuse is good, check voltage at the fuse. If
voltage is missing, ensure yellow wire is properly crimped to vehicles
battery supply (Go to step 10 of this installation guide. If both wires are
supplying power to modules and radio still does not enter “Changer’ mode,
either the radio has not been programmed to support a CD changer or
module is defective, however to reduce that possibility, each module is
individually tested on our SC-816 radio prior to shipping.
7. With engine running there is a high pitch squeal that increases with
engine speed. What can be done to remedy this?
If you experience alternator whine (increases with engine speed), we
recommend installing a noise filter (e.g. NF3A) or similar.
Here is how to install our Noise Filter:
Filter connects to red accessory wire.:
- Connect module red wire to filter (out) red wire
- Connect filter (in) red wire to car accessory supply wire
- Connect filter black wire to ground
