RADIO RECEPTION FACTORS
Three factors can affect radio reception:
•Distance/strength.The further an FM signal travels, the weaker it is.
The listenable range of the average FM station is approximately 40 km
(24 miles). This range can be affected by “signal modulation.” Signal
modulation is a process radio stations use to increase their
strength/volume relative to other stations.
•Terrain.Hills, mountains and tall buildings between your vehicle’s
antenna and the radio station signal can cause FM reception problems.
Static can be caused on AM stations by power lines, electric fences,
traffic lights and thunderstorms. Moving away from an interfering
structure (out of its “shadow”) returns your reception to normal.
•Station overload.Weak signals are sometimes captured by stronger
signals when you pass a broadcast tower. A stronger signal may
temporarily overtake a weaker signal and play while the weak station
frequency is displayed.
The audio system automatically switches to single channel reception if it
will improve the reception of a station normally received in stereo.

1. Press and hold the two outside
buttons releasing only when the red
light begins to flash after 20
seconds.Do notrepeat step one to
program additional hand-held
transmitters to the remaining two
HomeLinkbuttons. This will erase
previously programmed hand-held
transmitter signals into HomeLink.
2. Position the end of your
hand-held transmitter 2–8 cm (1–3
inches) away from the HomeLinkbutton you wish to program (located
on your overhead console) while keeping the red light in view.
3. Simultaneously press and hold
both the HomeLinkand hand-held
transmitter button.Do not release
the buttons until step 4 has been
completed.
Some entry gates and garage door
openers may require you to replace
step 3 with procedures noted in the
“Gate Operator and Canadian
Programming” section for Canadian
residents.
4. The red light will flash slowly and then rapidly. Release both buttons
when the red light flashes rapidly. (The rapid flashing light indicates
acceptance of the hand-held transmitters’ radio frequency signals.)
5. Press and hold the just-trained HomeLinkbutton and observe the red
light. If the light is a constant red, programming is complete and your
device should activate when the HomeLinkbutton is pressed and
released.Note:To program the remaining two HomeLinkbuttons,
begin with step 2 in the “Programming” section —do notrepeat step 1.
Note:If the red light blinks rapidly for two seconds and then turns to a
continuous red, proceed with steps 6 through 8 to complete
programming of a rolling code equipped device.
6. At the garage door opener receiver (motor-head unit) in the garage,
locate the “learn” or “smart” button (usually near where the hanging
antenna wire is attached to the unit).
7. Press and release the “learn” or “smart” button. (The name and color
of the button may vary by manufacturer.)
