CONNECTING POWER

You can power your system from either of these sources:

standard AC power, using the supplied AC power cord

internal battery power, using eight C bat- teries (not supplied)

Connecting the power cord to the system au- tomatically disconnects the internal batteries.

INSTALLING BATTERIES

You can power your system with eight C bat- teries. For the best performance and longest life, we recommend RadioShack alkaline batteries.

Cautions:

CONNECTING AC POWER

Plug the supplied AC power cord into the AC jack on the back of the system, then plug the other end into a standard AC outlet.

Cautions:

Always connect the AC power cord to the system before you connect it to AC power. When you finish, disconnect the power cord from AC power before you disconnect it from the system.

Both ends of your system's power cord are designed to fit only one way. If you have difficulty connecting the power cord to the AC jack or the plug into the outlet, do not force it! Turn the power cord and try again.

Use only fresh batteries of the required size and recommended type.

Do not mix old and new batteries, differ- ent types of batteries (standard, alka- line, or rechargeable), or rechargeable batteries of different capacities.

Follow these steps to install batteries into the system.

1.Press down the tabs on the battery com- partment cover, and pull the cover to remove it.

2.Place the batteries in the compartment as indicated by the polarity symbols (+ and –) marked outside the compart- ment.
