User Manual Remote Control ERF2*36H*, supporting Wireless Communication. It’s main functions: Keyboard operation; ERF2*36H* Components ERF2*36H* mainly consists of one PCB (printed circuit board) which contains a MCU&BT chip. ERF2*36H* contains an implementation of bluetooth technology, with integrating a bluetooth chip and a printed antenna. ERF2*36H* is controlled byXF2472C. It will operate at infrared mode before paired with the host. The bluetooth technology this remote control used accords with Bluetooth 4.2 Low Energy standard. It operates in the 2.4GHz ISM band, and the frequency band is 2402 ~ 2480MHz. There are 40 channels numbered 0~39. The bandwidth of each channel separation is 2MHz. FCC NOTICE: 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. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. 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. FCC Radiation Exposure Statement This equipment complies with FCC radiation exposure limits set forth for uncontrolled environment. ISED Regulatory Compliance Statements： This device contains licence-exempt transmitter(s)/receiver(s) that comply with Innovation, Science and Economic Development Canada’s licence-exempt RSS(s). Operation is subject to the following two conditions: (1) This device may not cause interference. (2) This device must accept any interference, including interference that may cause undesired operation of the device. This equipment complies with the ISED portable RF exposure limit set forth for an uncontrolled environment and are safe for intended operation as described in this manual. The further RF exposure reduction can be achieved if the product can be kept as far as possible from the user body or set the device to lower output power if such function is available.
