Scientific Atlanta 3270HD Before You Begin

Before You Begin

•Read the IMPORTANT RULES FOR SAFE OPERATION section of this guide.

•Locate the serial number for your set- top, which is on a bar code on the back panel of the set-top. You will need this serial number to activate service with your cable service provider and to join the Explorer eClub. Also, if your system requires troubleshooting in the future, your cable service provider or Scientific-Atlanta may ask for the serial number.

•If you plug the set-top into an outlet that is controlled by a wall switch, keep the switch in the ON position. The on- screen guide is updated nightly. If the wall switch is in the OFF position, your set-top will not receive the latest programming updates.

•Keep the top of the set-top free of all objects and electronic devices, including your TV.

•It is recommended that you connect a surge protector to your cable equipment and electronic devices.
