The following are general troubleshooting seteps that address most of the issues that can occur with an infrared (IR) remote control. An IR-mark identifies a infrared remote control and is usually located at the bottom part of the remote, near the model number.
Before you start
- Check the remote control for damage. A damaged remote control should be replaced.  Go to Parts and Accessories.
- Make sure the device to be controlled is on and functional. Press the power button directly on the device, not the remote control.
- Make sure you are within 3-10 feet of your device and pointing the remote control at the IR sensor of the device.
Check the remote control after each step to determine if it is working. If you need model-specific information, check your manuals .
Review the short tutorial or skip to the steps below.
- Remove any objects that may block the IR signal between your remote control and the device.

- Reset the remote control.
- Remove the batteries from the remote control.
- Press each button on the remote control twice to discharge the power.
