Troubleshooting 5 Using headphones (not supplied) For private listening, you can connect headphones with a 1/8" plug to the headphone jack on the left side of the TV. Connecting headphones automatically mutes the built-in speakers. 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. • After you set the volume, do not increase it. Over time, your ears adapt to the volume level. A volume level that does not cause discomfort may still damage your hearing. Using an external antenna (not supplied) If you are in an area with weak TV signals or inside a concrete building, you may need an external antenna to improve reception. To connect an external antenna: • Connect the external antenna to the RF IN jack on the right side of the TV. Use the supplied L-shaped F-connector adapter if necessary. Troubleshooting Problem Resolution There is no sound or power. The picture quality is poor. There is no sound when using headphones. • Increase the volume level. • If using the built-in battery, connect the AC power adapter. • If the picture is not clear with the built-in rod antenna, try placing your TV near a window or connecting an external antenna to the TV to improve reception. • Reinsert the headphone plug into the jack. • Increase the volume level.
