Akiko User’s GuidePL5552 Akiko Transmitter for analog audio Model: PL5552 Works WithDevices with a 3.5 mm analog jack (sometimes referred to as AUX ports) RequirementsThe device must support analog audio in NotesSee page 3 for details on the IR learning feature. Akiko User’s GuidePL5552 Akiko User’s GuidePL5552 IR Learning Control volume on Akiko using your existing remote Akiko offer a feature called IR learning. This feature allows you to teach your transmitter to use your existing TV remote to adjust the volume on your SKAA speakers. To setup IR Learning with your existing remote: Within 14 seconds of plugging the transmitter into a USB power source, press the Volume (+) button, on your desired remote, while aiming it at the IR sensor on the transmitter. A brief flash of the transmitter’s LED will indicate that it has received the Volume (+) signal from the remote. Next, press the Volume (-) button, on your remote. Another brief flash of the LED will indicate that the transmitter has received the Volume (-) signal, from the remote Finally, press the Mute button on your remote. If successful, the transmitter’s LED will turn on for two seconds to indicate that it has successfully learned which volume buttons you will be using on your desired remote. Plug your audio cable into your transmitter’s jack. You may begin using your remote with your transmitter. If any errors were detected, during the IR learning process, the LED will blink rapidly, four consecutive times. In this case, unplug the transmitter from the USB power source and restart the IR learning process. Plug your transmitter into a USB port, for power. (Make sure nothing is plugged into the transmitter’s jack during this stage.) To Unlearn a remote control, simply press any button on the remote, flashes of the LED indicate a successful Unlearn. Akiko User’s GuidePL5552 FCC Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: - Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body.
