POWER indicator
This indicator glows when the unit's power
is turned ON.
2
COOLING FAN indicator
When the unit's internal temperature rises,
the side fan is activated. If the internal
temperature rises even further, the slide
panel opens automatically, and the cooling
fan on the top is activated.
Whilst the top cooling fan is in operation,
the COOLING FAN indicator blinks.
3
OPERATION/PROTECTION
indicator
This indicator glows when the power
comes ON normally.
If the PROTECTION function is activated,
the indicator blinks or goes out.
4
LOW VOLTAGE indicator
This indicator glows when the power
voltage falls below 11V (volts).
If the power supply voltage returns to full
after a voltage drop, this indicator will blink
to alert the user that a voltage drop has
occurred.
The number of blinks indicates the number
of times the voltage has dropped (up to a
maximum of 10).
5
B.M.S. indicator
This indicator glows when the bass boost is
turned ON using the B.M.S. (See P.6).
If indicators 2 to 5 light up in succession or
blink in unison, the system is in DEMO mode.
If this happens, cancel DEMO mode by
pressing the OPEN/CLOSE button.
■
PROTECTION function
This unit incorporates a protection function
which protects the main unit and speakers
from troubles. The unit stops to function
when the protection function is activated.
• When the
OPERATION/PROTECTION indicator
blinks:
• A speaker cable may be short-circuited.
• A speaker output may be in contact with
the ground.
• The temperature of the internal parts may
be higher than 120°C (248°F)
• The fuse of this unit may be blown.
• The unit may be malfunctioning and
sending DC signal to the speaker output.
• When the POWER indicator and the
OPERATION/PROTECTION function
both go out:
• The fuse of this unit may be blown.
• When the LOW VOLTAGE indicator
glows or blinks:
• Is the battery exhausted?
• The car battery has a small capacity.
• If the battery cable is too thin or too long,
it will not be able to supply enough
power.
• Is the battery cable deteriorated?
