PRECAUTIONS
• Be sure to disconnect the cable from the (–) battery post before installing
your DAI-C990. This will reduce any chance of damage to the unit in case of a
short-circuit.
• Be sure to connect the color coded leads according to the diagram. Incorrect
connections may cause the unit to malfunction or damage to the vehicle’s
electrical system.
• When making connections to the vehicle’s electrical system, be aware of the
factory installed components (e.g. on-board computer). Do not tap into these
leads to provide power for this unit. When connecting the DAI-C990 to the
fuse box, make sure the fuse for the intended circuit of the DAI-C990 has the
appropriate amperage. Failure to do so may result in damage to the unit and/
or the vehicle. When in doubt, consult your ALPINE dealer.
• The DAI-C990 uses female RCA-type jacks for connection to other units (e.g.
amplifier) having RCA connectors. You may need an adaptor to connect other
units. If so, please contact your authorized ALPINE dealer for assistance.
• Be careful not to cause a short by jamming the cable into the computer when
connecting. It can cause a fault.
• Alpine accepts no responsibility for damaged or lost data in your computer
etc., even if data etc., is damaged or lost while using this product.
WARNING
Wiring Connections
Improper wiring connections could cause
serious damage to your audio system. Be
sure you:
1. DO NOT connect (–) wires from left and
right speakers together.
2. DO NOT ground any speaker wires.
3. DO NOT run wires where they may be
pinched or cut.
4. DO NOT leave bare speaker terminals ex
posed. They may contact the vehicle
chassis and cause a short.
Fuse
When replacing the fuse(s), the replacement
fuse must be of the same amperage as shown
on the fuse holder. If the fuse(s) blows more
than once, carefully check all electrical
connections for shorted circuitry. Also have
your vehicle’s voltage regulator checked. Do
not attempt to repair the unit yourself; return
it to your Alpine dealer or nearest Alpine
Service Station for servicing.
Temperature
In order to ensure proper performance, be
sure the temperature in your vehicle is above
14
°
F (–10
°
C) and below 140
°
F (60
°
C)
before turning your unit on. Good air
circulation is essential to prevent internal
heat build-up in the unit.
Installation Location
Make sure the DAI-C990 will not be
installed in a location subjected to:
• Direct sun and heat
• High humidity and water
• Excessive dust
• Excessive vibrations
Maintenance
If you have problems, do not attempt to
repair the unit yourself. Return it to your
Alpine dealer or the nearest Alpine Service
Station for servicing.
