6. TIPS FOR OPERATING THE AUDIO SYSTEM
PRIUS_Navi_OM47E22U_(U)
20.03.26 18:17
Fading: AM broadcasts are reflected by
the upper atmosphere — especially at
night. These reflected signals can interfere
with those received directly from the radio
station, causing the radio station to sound
alternately strong and weak.
Station interference: When a reflected sig-
nal and a signal received directly from a ra-
dio station are very nearly the same
frequency, they can interfere with each
other, making it difficult to hear the broad-
cast.
Static: AM is easily affected by external
sources of electrical noise, such as high
tension power lines, lightening or electrical
motors. This results in static.
Cargo loaded on the roof luggage carrier,
especially metal objects, may adversely
affect the reception of XM Satellite Radio.
 Alternation or modifications carried out
without appropriate authorization may
invalidate the user’s right to operate the
equipment. 
