YZTDONARBT1280MINI Keyboard

Bluetooth Keyboard User’s Manual Step 1). Plug the USB Dongle in a USB port of the PC or notebook. (If the PC or notebook already has a Bluetooth receiver, then no need the USB Dongle) Photo(1) Step 2). Open the cover of the battery slot and install two pieces of 1.5V AAA battery. Then cover the battery slot. Make sure that the batteries’ poliarities are in accordance with the polarity marks in the battery slot. Photo(2) Photo(3) Step 3). Push the Power Switch to ON as shown in the following phot (4) and then press the PAIR button. The Bluetooth Synch LED will wink as shown in photo (5). photo(4) photo(5) Step 4). The Bluetooth keyboard will automatically search for Bluetooth paired device after the PAIR button was pressed. A corresponding dialog box will pop up on the screen of the PC or Notebook—as shown in the following photo (6). Input the security code which displays on the dialog box by the Bluetooth keyboard and press Enter. When the Bluetooth Synch LED stop winking, it means the Bluetooth connection was established successfully between the keyboard and the computer. photo（6） Step 5). It will take a few seconds for the computer to automatically install some drivers once the Bluetooth connection has been established. Upon installation of the drivers, the Bluetooth keyboard is ready to work. As long as the PAIR button was not pressed again or the Paired device was not removed, users no need to make pairing any more after the pairing process was accomplished, even the batteries were took out from battery slot. 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. To assure continued compliance, any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment. (Example- use only shielded interface cables when connecting to computer or peripheral devices). FCC Radiation Exposure Statement This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. This equipment 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. Caution! The manufacturer is not responsible for any radio or TV interference caused by unauthorized modifications to this equipment. Such modifications could void the user authority to operate the equipment.
