Maintenance and Precautions
FM car antenna
When tuning in FM stations while the vehicle is moving, the vehicle will pass through
changing signal conditions ranging from strong signals near broadcast stations to
extremely weak signals. If any FM antenna is not used, the sensitivity may be reduced and
the noise may increase as the signal conditions keep changing, For FM reception with a
good sound quality and minimal noise, it is recommended that you attach a special FM car
antenna.
Protection circuits
The protection circuits inside the unit function in the following circumstances.
- When the speaker terminals have been shorted.
- When the covering of the speaker cords has been worn away or cut and the wires inside
are touching the vehicle body.
- When the inside temperature has risen due to some cause or other.
- When an overcurrent has flowed and the supply voltage has increased to an abnormal
level.
If he protection circuits function during operation, find out what is wrong before continuing
operation. No sound is heard through the speakers while these circuits are functioning.
Replacing the fuse
If the fuse has blown, replace with a fresh unit having the same amperage. If the new fuse
blows as soon as it is inserted, there may be something wrong with the unit. In cases like
this, contact your dealer.
- When opening the fuse holder, always make sure that the ignition is switch off.
