PROBABLE CAUSE
No DC voltage to the
transceiver, or blown
fuse.
R e v e r s e d p o w e r
wires.
Engine noise.
Accessory cable.
Antenna.
T h e p o w e r s u p p l y
voltage is too high or
too low.
Accessory cable.
Setting of the GPS
navigation receiver.
REMEDY
a. Check the 12 VDC battery connections and
the fuse.
b. The VOL knob needs to be rotated clock-
wise to turn the radio on.
Check the power cable for DC voltage, or re-
place the fuse (6 A 250 V).
Make sure the red wire is connected to the
positive (+) battery post, and the black wire is
connected to the negative (-) battery post. If
the fuse still blows, contact your Dealer.
Reroute the DC power cables away from the
engine. Add noise suppressor on power cable.
Change to resistive spark plug wires and/or
add an alternator whine filter.
Check the connections of the accessory cable
(Possible short circuit on the External speaker
cable WHITE/SHIELD).
Have the antenna checked or test the trans-
ceiver with another antenna. If the problem
persists, contact your Dealer for servicing.
Confirm that the connected power supply volt-
age is between 10 volts and 17 volts DC. Con-
firm that the generator has not malfunctioned.
Check the accessory cable connection.
Some GPS use the battery ground line for
NMEA connection.
Check the output signal format of the GPS
navigation receiver. This radio requires
NMEA0183 format with GLL, RMC, GGA, or
GNS sentence as an output signal. If the GPS
has a baud rate setting make sure to select
4800 and parity to NONE.
