Caution: If you are not going to use the remote control for a month or more, remove its batteries. Batteries can leak damaging chemicals.

You can use the remote control up to a distance of about 25 feet. If the re- mote control operates erratically or does not work, replace both batteries.

USING HEADPHONES

You can use headphones (not sup- plied) to listen in privacy. Insert the headphones’ 1/8-inch (3.5 mm) plug in- to the PHONES jack.

Listening Safely

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

•Do not listen at extremely high volume levels. Extended high- volume listening can lead to per- manent hearing loss.

•Set the volume to the lowest set- ting before you begin listening. Af- ter 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 volume level, so a volume level that does not cause discomfort might still damage your hearing.
