In Case of Difficulty
Cause and Solution
Incorrect Switch Settings: Make sure that all
Mode Selector switches are in their correct
positions for your system configuration (see
WIRING AND SETUP).
Defective or disconnected audio cables:
check for continuity and replace if neces-
sary.
Incorrect Output Level Adjustment: Verify
that the PXA-H600's output level controls
are not turned very low. If they are, sound
output level may be very low and may give
the impression that the system (or part of the
system) is dead.
Defective PXA-H600: Bypass the PXA-H600
by connecting its input and the dead output
terminal's cables together (with a pair of
Alpine 4402 female-to-female adaptors). If
the system becomes functional, the PXA-
H600 may be defective. Consult your Alpine
dealer.
Defective Head Unit, or other audio
component:
Check each component for wiring and
operation.
Ground loops: Connect grounds of all audio
components to the same point on the vehicle
chassis.
Verify that this point is a true ground by
checking for continuity with an ohmmeter
between the ground point and the battery's
(—) terminal, and follow the grounding
recommendations on the GUIDE FOR
INSTALLATION AND CONNECTIONS.
Shorted Signal and Chassis Grounds: Check
for shorts between speaker leads and
chassis ground, or input signal ground and
chassis ground.
The other audio components may have
insufficient filtering: They may need noise
suppressors on their battery or ignition
connections.
Check the vehicle's battery and voltage
regulator.
