Using this remote is really easy. First, insert 2 x AAA batteries into the battery compartment. Once the batteries are in, you can start using the remote. To turn on or off a device, press the power button. Use the channel up and down buttons to switch channels, and the volume up and down buttons to adjust the sound. The AV button can be used to switch between different audio - visual sources, and the Mute button will silence the sound. When changing the batteries, don't worry about losing the settings as they will remain the same. Keep the remote in a dry and clean place. Avoid exposing it to extreme temperatures or moisture. If it gets dirty, you can use a soft, dry cloth to gently wipe it. If you find that the remote doesn't work with your equipment, don't hesitate to contact us for a refund or exchange, just keep in mind that postage costs won't be refunded.
