COOLING FAN indicator

When the unit's internal temperature rises,

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).

sending DC signal to the speaker output.

• The sigma servo connection may be

erroneous.
Cancelling: turn the accessory power

source (ACC) OFF, then back ON.

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?
