USING HEADPHONES

Sometimes headphones can capture the subtle difference between
signals and the surrounding noise that often occurs at night. Be
sure that the headphones (not supplied) have a

-inch plug. Insert

the plug into the jack on the left of the receiver. When you plug in
the headphones, the speaker is silenced. You will find a wide selec-
tion of headphones at your local RadioShack store.

Listening Safely

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

• Set the volume 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 high-

volume 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.
