• Make sure that batteries are disposed of correctly. Do not burn or incinerate.
Notes
• Do not mix batteries of different types.
• Do not mix old and new batteries.
• Remove batteries when the charge is depleted.
• If the remote control is not going to be used for an extended period of time, remove the batteries.
Aiming the remote control
• Point the remote control towards the remote sensor on the front of your TV.
Setting up your TV
When you turn on your TV for the first time, Guided Setup starts. During Guided Setup:
• Your TV automatically detects your wireless network, so have your network name and password handy and follow the easy on-screen instructions.
• You’ll be prompted to create your Roku account online at website. Your TV generates a unique code that links your TV to your new account.
Note Roku accounts are free, and while a valid credit card number is not required, providing your card information makes renting and purchasing entertainment a breeze.
• After you are connected to your account, your TV automatically updates with the latest software, and you can start streaming immediately.
Note If you aren’t ready to connect your TV to a wireless network, you can still use it as a regular TV.
Maintaining
• Do not use your TV in areas that are too hot or too cold, because the cabinet may warp or the screen may malfunction. Your TV works best in temperatures that are comfortable to you.
• Storage temperatures are 5° to 113°F (-15° to 45°C).
• Working temperatures are 41° to 95°F (5° to 35°C).
• Do not place your TV in direct sunlight or near a heat source.
Cleaning your TV cabinet
Clean the cabinet with a soft, lint-free cloth. If the cabinet is especially dirty, moisten a soft, lint-free cloth in a weak detergent solution, squeeze the excess moisture from the cloth, then wipe the cabinet with the cloth. Use a clean cloth to dry the cabinet.
Cleaning your TV screen
Clean the screen with a soft, lint-free cloth.
