Battery Safety
This product contains alkaline. The remote for your Fire TV Cube requires batteries for use. Only use new 1.5V alkaline or 1.2 NiMH rechargeable AAA sized batteries. Never mix old and new batteries. Keep all of the batteries out of the reach of children. Do not open, disassemble, puncture, cut, bend, shred, or heat the batteries and do not allow metal objects to touch the battery terminals on the remote as they can become hot and cause burns. Remove all batteries if they are worn out or before storing your remote for an extended period of time. Dispose of all batteries in accordance with applicable laws and regulations and do not dispose of batteries by throwing them into a fire. If any batteries begin to leak, take steps to prevent the fluid from coming into direct contact with skin or clothes as the fluid could be corrosive and may be toxic. Remove the batteries and clean the battery compartment in accordance with the battery manufacturer's recommendations.
Other Safety Considerations
- A small percentage of people may be susceptible to blackouts or seizures (even if they have never had one before) when exposed to flashing lights or light patterns, such as when watching video or playing games. If you have experienced seizures or blackouts or have a family history of such occurrences, you should consult a doctor before watching videos or playing games.
- Engaging in repetitive motions such as pressing buttons or playing some games may cause you to experience occasional discomfort in your hands, arms, shoulders, neck, or other parts of your body.
- Discontinue use of your device and consult a physician if you experience headaches, blackouts, seizures, convulsion, eye or muscle twitching, loss of awareness, involuntary movement, disorientation, or other discomfort. To reduce risk of these symptoms avoid prolonged use, watch your television from a far distance and in a well-lit room, and take frequent breaks.
- Handle your device and its accessories with care. Your device or its accessories may have pointed edges which can lead to scratches, cuts, or other physical injury.
- Small parts contained in your device and its accessories may present a choking hazard to small children.
- The American Academy of Pediatrics recommends that television should be avoided for infants and children under age 2.
- Your device is shipped with an AC adaptor. Your device should only be powered using the AC adaptor included with the device.
- If the adaptor or cable appears damaged, discontinue use immediately.
- Power adaptor designed only for use with Fire TV Cube.
- Your device is shipped with an Amazon IR Extender which was designed only for use with the FireTV Cube.

Using Your Fire TV Cube and Alexa Voice Remote around Other Electronic Devices
The Fire TV Cube and Alexa Voice Remote generate, use, and can radiate radio frequency (RF) energy and, if not used in accordance with their instructions, may cause interference to radio communications and electronic equipment. External RF signals may affect improperly installed or inadequately shielded electronic operating systems, entertainment systems, and personal medical devices.
