Cautions:

You must use a Class 2

!power source that supplies 12 volts DC and delivers at

least 100 mA. Its center tip must be set to positive and its plug must fit the transmitter's DC 12V jack. The supplied adapter meets these speci- fications. Using an adapter that does not meet these specifications could damage the transmitter or the adapter.

Always connect the AC adapter to the transmitter before you connect it to AC power. When you finish, dis- connect the adapter from AC power before you disconnect it from the transmitter.

Plug the supplied AC adapter’s barrel plug into the transmitter’s DC 12V jack, then plug the adapter into a standard AC outlet.

INSTALLING BATTERIES

To power the headphones’ receiver, use the three supplied AAA nickel-cadmium rechargeable batteries. Or, you can use three AAA alkaline batteries (not sup- plied, available at your local RadioShack store).

Cautions:

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

Do not mix old and new batteries, different types of rechargeable bat- teries, or rechargeable batteries of different capacities.

Follow these steps to install batteries.

1.Remove the battery compartment cover on the left earpiece by push- ing up the tab and pulling the cover up in the direction of the arrow.

2.Place the batteries over the ribbon in the compartment, as indicated by the polarity symbols (+ and –) in the illustration.

3.Replace the cover.
