Convenient features
• Station Swapping - As a FM signal
weakens, another more powerful
signal near the same frequency may
begin to play. This is because your
radio is designed to lock onto the
clearest signal. If this occurs, select
another station with a stronger signal.
• Multi-Path Cancellation - Radio signals
being received from several directions
can cause distortion or fluttering.
This can be caused by a direct and
reflected signal from the same station,
or by signals from two stations with
close frequencies. If this occurs, select
another station until the condition has
passed.

Using a cellular phone or a two-way
radio
When a cellular phone is used inside
the vehicle, noise may be produced
from the audio system. This does not
mean that something is wrong with the
audio equipment. In such a case, use
the cellular phone at a place as far as
possible from the audio equipment.
NOTICE
OJF045311L OJF045311L
When using a communication system
such as a cellular phone or a radio set
inside the vehicle, a separate external
antenna must be fitted. When a cellular
phone or a radio set is used with an
internal antenna alone, it may interfere
with the vehicle's electrical system and
adversely affect safe operation of the
vehicle.
WARNING
Do not use a cellular phone while
driving. Stop at a safe location to use a
cellular phone.
