2003 CHEVROLET ASTRO CARGO VAN radio antenna

5. Press and hold the newly-trained HomeLinkžbutton
and observe the indicator light.
If the indicator light stays on constantly,
programming is complete and your device should
activate when the HomeLink
žbutton is pressed and
released.
To program the remaining two HomeLink
žbuttons,
begin with Step 2 under ªProgramming HomeLinkž.º
Do not repeat Step 1 as this will erase all of the
programmed channels.
If the indicator light blinks rapidly for two seconds
and then turns to a constant light, continue with
Steps 6 through 8 following to complete the
programming of a rolling-code equipped device
(most commonly, a garage door opener).
6. Locate in the garage, the garage door opener
receiver (motor-head unit). Locate the ªLearnº
or ªSmartº button. This can usually be found where
the hanging antenna wire is attached to the
motor-head unit.
7. Firmly press and release the ªLearnº or ªSmartº
button. The name and color of the button may
vary by manufacturer.
You will have 30 seconds to start Step 8.8. Return to the vehicle. Firmly press and hold the
programmed HomeLink
žbutton for two seconds,
then release. Repeat the press/hold/release
sequence a second time, and depending on the
brand of the garage door opener (or other rolling
code device), repeat this sequence a third time
to complete the programming.
HomeLink
žshould now activate your rolling-code
equipped device.
To program the remaining two HomeLink
žbuttons,
begin with Step 2 of ªProgramming HomeLinkž.º Do not
repeat Step 1.
Gate Operator and Canadian
Programming
Canadian radio-frequency laws require transmitter
signals to ªtime outº or quit after several seconds of
transmission. This may not be long enough for
HomeLink
žto pick up the signal during programming.
Similarly, some U.S. gate operators are manufactured to
ªtime outº in the same manner.
If you live in Canada, or you are having difficulty
programming a gate operator by using the
ªProgramming HomeLink
žº procedures (regardless of
where you live), replace Step 3 under ªProgramming
HomeLink
žº with the following:

Understanding Radio Reception
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble to reduce this noise if you ever get it.
FM
FM stereo will give you the best sound, but FM signals
will reach only about 10 to 40 miles (16 to 65 km).
Tall buildings or hills can interfere with FM signals,
causing the sound to come and go.
Care of Your CDs
Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust. If the surface of a disc is soiled, dampen
a clean, soft cloth in a mild, neutral detergent solution
and clean it, wiping from the center to the edge.
Be sure never to touch the side without writing when
handling discs. Pick up discs by grasping the outer
edges or the edge of the hole and the outer edge.
Care of Your CD Player
The use of CD lens cleaner discs is not advised, due to
the risk of contaminating the lens of the CD optics
with lubricants internal to the CD mechanism.
Fixed Mast Antenna
The ®xed mast antenna can withstand most car washes
without being damaged. If the mast should ever
become slightly bent, you can straighten it out by hand.
If the mast is badly bent, as it might be by vandals,
you should replace it.
Check occasionally to be sure the mast is still tightened
to the fender. If tightening is required, tighten by
hand, then with a wrench one quarter turn.
