power, even with trans-
ceiver set to HI power.
“HI BATTERY” or “LO

wires.
Engine noise.
Accessory cable.
Antenna.
The power supply
voltage is too high or
too low.
Accessory cable.
Setting of the GPS
navigation receiver.
REMEDY
a. Check the 12VDC battery connections and
the fuse.
b. The PWR key needs to be pressed and held
to turn the radio on.
Check the power cable for DC voltage, or re-
place the fuse (6A 250V).
Make sure the red wire is connected to the posi-
tive (+) battery post, and the black wire is con-
nected 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 per-
sists, contact your Dealer for servicing.
Confirm that the connected power supply volt-
age is not 17 volts or lower than 10 volts. 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 navi-
gation receiver. This radio requires NMEA0183
format with GLL, RMB, 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.
