Jeep 2008 Patriot - Manual (Page 195)

EVIC button will place the Compass in calibration mode.
The Cal indicator will come on continuously in the EVIC
display, to indicate that the compass is now in the
calibration mode and that the vehicle can now be driven
to calibrate. A short EVIC button press from the
ЉCali-
brate Compass (Yes) Љ screen will exit the EVIC Customer
Programmable features, and return it to its normal oper-
ating mode. To complete the compass calibration, drive
the vehicle in one or more complete 360 degree circles
under 5 mph (8 km/h) in an area free from power lines
and large metallic objects, until the CAL indicator turns
off. The compass will now function normally.
RADIO GENERAL INFORMATION
RADIO BROADCAST SIGNALS
The radio will provide excellent reception under most
operating conditions. Like any system, however, automo-
tive radios have performance limitations, due to mobile
operation and natural phenomena, which might lead you
to believe your sound system is malfunctioning. To help
you understand and save you concern about these “ap-
parent” malfunctions, you must understand a point or
two about the transmission and reception of radio sig-
nals.
Electrical Disturbances
Radio waves may pick up electrical disturbances during
transmission. They mainly affect the wave amplitude,
and thus remain a part of the AM reception. They
interfere very little with the frequency variations that
carry the FM signal.
