PREPARATION
CONNECTING TO POWER
You can power the receiver from internal batteries, standard AC power, or your vehicle’s battery.
Installing Batteries
You can use three AA batteries (not supplied) to power the receiv­er. For the best results and longest life, we recommend alkaline batteries such as RadioShack Cat. No. 23-552.
Cautions:
• Always use 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 the batter ies.
1. Open the battery compartment cover by pressing on the dotted portion and slid­ing it in the direc ti on of the arrow below.
(
2. Slide three AA batteries into the compartment according to the polarity symbols (+ and –) marked inside.
3. Close the cover.

Cautions:
• If you will not be using battery power or if you will only use an
adapter for several months, remove the batteries.
• Dispose of old batteries pr omptly and properly.
Using Standard AC Power
To power the receiver from standard AC power, you need an op­tional AC adapter, such as Cat. No. 273-1662.
Note: Connecting an AC adapter di sconnects internal batteries.
Cautions:
• The AC adapter must be capable of delivering 4.5 volts, its
center tip must be set to negative, it must deliver at least 200 milliamps, and its barrel plug must properl y fit the rec eiver’s
jack. The recommended adapter m eets these specifica-
IN 4.5V
tions. Usin g an adapter that does not meet these specifications could damage the receiv er or the adapter.
• When you finish using the AC adapter, unplug it from the AC
outlet first, then disconnect it from the re ceiver.

1. Set the adapter’s volt age switch to 4.5V.
2. Line up the 5.5 mm outer diameter/2.1 mm inner diameter bar­rel plug with the adapter’s socket so it reads –TIP, and insert the plug into the socket.
3. Insert the barrel plug into the receiver’s
DC IN 4.5V
jack.
4. Plug the adapter into a standard AC outlet.
Using Vehicle Battery Power
To power the receiver from your vehicle’s battery, you need an op­tional DC cigarette lighter adapter, such as Cat. No. 270-1560.
Cautions:
• The DC cigarette lighter adapter must be capable of delivering
4.5 volts, its center tip must be set to negative, it must deliver at least 200 milliamps, and its barrel plug must properly fit the receiv er ’s these specifications. Using an adapter that does not meet these specifications could damage the receiver or the adapter.
• Always plug the DC cigarette lighter adapter into the receiver before you plug it into your vehicle's cigarette-lighter socket. Always unplug the adapter from the vehicle's cigarette-lighter socket before you unplug it from the receiver.

Listening Safely
To protect your hearing, follow these guidelines when you use an earphone or headphones.
• Do not listen at extremely high volum e le vels. Extended high­volume listening can lead to permanent hearing loss.
• Set the volume to t he lowest setting before you begin listening. After you begin listening, adjust the volume to a comfortable level.
• Once you set the volume, do not increase it. Over time, your ears adapt to the volum e level, so a volume level that does not cause discomfort might still damage your hearing.
