Note: If you do not remove the shipping screws from the CD changer, the
changer will not operate.
Save the shipping screws in case you might want to install the CD changer
in another vehicle. You can secure them to the back of the CD changer
with a piece of tape.
Installing The Remote Control's Batteries
Your infrared remote control requires 2 AAA batteries (not supplied) for
power. For the best performance and longest life, we recommend RadioShack
alkaline batteries.
CAUTIONS: Use only fresh batteries of the required size and recommended
type.
Do not mix old and new batteries, different types of batteries
(standard, alkaline, or rechargeable) or rechargeable batteries
of different capacities.
Follow these steps to install batteries.
1. Slide the battery compartment cover in the direction of the arrow to
remove it.
2. Place the batteries in the compartment as indicated by the polarity
symbols (+ and -) marked inside.
3. Replace the cover.
When the remote control stops operating properly, replace the batteries.
WARNING: Dispose of old batteries promptly and properly. Do not burn or
bury them.
CAUTION: If you do not plan to use the remote control for a long time,
remove the batteries. Batteries can leak chemicals that can
destroy electronic parts.
