If you have an outside VHF TV
antenna, you can use a signal splitter
with a 300-ohm output to connect
your stereo system and TV set to the
same antenna. Your local Ra­dioShack store has a wide sel ection
of antennas, connectors, and split­ters.

INSTALLING THE
REMOTE CONTROL’S
BATTERIES

The remote control requires two AAA
batteries (not supplied) for power.
For the best performance and long­est life, we recommend alkaline
batteries, such as RadioShack Cat.

Listening Safely

To protect your hearing, follow these
guidelines when you use head­phones.

• Set the vol u me to the lowest set­ting before you begin listening.
After you begin listening, adjust
the volume to a comfortable
level.

• Do not listen at extremely high
volume levels. Extended high­volume listening can lead to
permanent 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.
