Using headphones/Dual Play mode

WARNING: Do not leave children unattended in the vehicle and
do not let children operate the system while unsupervised. If
wired headphones or auxiliary systems are used, children may become
entangled in the cords and seriously injure themselves.
Plug a 3.5 mm headphone (not included) into the
speaker button, or the 2/4 preset buttons simultaneously on the radio to
activate the headphones. The words DUAL PLAY will illuminate on the
radio display, sound will no longer be heard from the rear speakers and
the fade control will be disabled, signaling that Dual Play has been
activated.
The front speakers remain playing for the front passengers. Press the
speaker button, or the 2/4 preset buttons simultaneously on the radio
again to deactivate the headphones and dual play mode. The words
SINGLE PLAY will illuminate on the radio display and fade control and
sound from rear speakers will be restored, signaling that Dual Play mode
has been deactivated.
To use any rear controls, whether in single or dual play mode, the rear
seat controls must be active. To enable Dual Play, the rear seat controls
must be active and
the rear seat radio controls previously.

GENERAL AUDIO INFORMATION

Radio frequencies:

AM and FM frequencies are established by the Federal Communications
Commission (FCC) and the Canadian Radio and Telecommunications
Commission (CRTC). Those frequencies are:
AM: 530, 540–1700, 1710 kHz
FM: 87.7, 87.9–107.7, 107.9 MHz

Radio reception factors:

There are three factors that can affect radio reception:
• Distance/strength: The further you travel from an FM station, the
weaker the signal and the weaker the reception.
• Terrain: Hills, mountains, tall buildings, power lines, electric fences,
traffic lights and thunderstorms can interfere with your reception.
• Station overload: When you pass a broadcast tower, a stronger signal
may overtake a weaker one and play while the weak station frequency
is displayed.
