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. NOTE 1: 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. NOTE 2: Any changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.

Circuit Description It’s a receiver device with a RF function for a Medical treatment device. The receiver device’s working voltage is 30V, its working current is less than 60mA when in operation. Frequency Range is 2.404~2.477GHz. and a clock frequency of 16MHz as base clock signal. This receiver device has 2 keys, one key was used to pair with the remote control , the other key was used to make the hospital bed down.It has a LED which shows the receiver device’s state. Press the pairing button of the receiver and the LED is on, then you have 10s to make the remote to pair with the receiver. The distance between the transmitter and the receiver should be less than 2 meters when we do the pairing action . Press the K_1 and K_2 of the transmitter simultaneously till the LED blinks , then the pairing operation is successful . If we can't see the LED blinking till it is off ,the pairing is fail.And the recriver’s LED is on whenever it is receiving a signal. And the receiver device’s electronic parameters are as follows: 1．Modulation： GFSK 2．Frequency Range： 2.404~2.477GHz 3．Transmitted Power: 0 dBm 4．Working Current： <6A 5．Ambient Temperature： -40—85°C 6．Power supply： DC 24 Voltage.(30 Voltage Max-Allowable) 7．PCB Material & Size： FR4 1.6mm 47.9*85mm 8.
