5.3 CONNECTOR FUNCTION DESCRIPTION
5.4 FUSE CHECK
-
No sounds and display output of external unit (the condition when the fuse is blown)
This product may receive excessive current if the power line connection of the external product is incorrect, such as Ground
connection failure.
The fuse P253 on TUNER AMP UNIT is used to protect this product from this excessive current.
Even though the fuse is blown, the sounds of Pre-out output and AUX input are output properly and also other functions work
correctly.
However, you cannot turn on the external product connected to this product as the power is not supplied if the fuse is blown.
(The symptom in this case is the sounds of external product are not output on this product when the external product is
connected on a vehicle.)
If you find the symptoms above, check if the fuse is not blown.
If you replace to a new fuse and the fuse is blown again (you cannot turn on the power of external product), check the power
connection (Ground) of external product.
