If you have an outside VHF TV anten-
na, you can use a signal splitter to
connect this system and a TV to the
same antenna. Your local RadioShack
store has a wide selection of antennas
and connectors.

CONNECTING POWER

To connect power, after making all
other connections, plug your system's
power cord into a standard AC outlet.

Caution: Your system's power cord
has a polarized plug (one blade is wid-
er than the other). If you have difficulty
inserting the plug into the outlet, do
not force it. Turn the plug over and try
again.

USING HEADPHONES

To listen without disturbing others, you
can connect a pair of
reo headphones (not supplied) to the
System 740. Your local RadioShack
store has a wide selection of stereo
headphones.

Listening Safely

To protect your hearing, follow these
guidelines when you use headphones.
• Set the volume to the lowest set-
ting before you begin listening.
After you begin listening, adjust
the volume to a comfortable listen-
ing level.
• Do not listen at extremely high
volume levels. Extended high-
volume listening can lead to per-
manent hearing loss.
• Once you set the volume, do not
increase it. Over time your ears
adapt to the volume level, so a
volume level that does not cause
discomfort might still damage your
hearing.
