Federal Communication Commission Interference 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 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. FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this 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. Industry Canada Statement This device complies with RSS-210 of the Industry Canada Rules. Operation is subject to the following two conditions:
1) this device may not cause interference and 2) this device must accept any interference, including interference that may cause undesired operation of the device Product Specification Product Name2.4GHz Cordless keyboard Model Name Y-R0009 Brand Name Logitech Antenna Type of Antenna (Loop....) antenna gain Method of Frequency generation Number of channels Carrier frequencies Index 1 2 3 4 5 6 RF channel 2405(0x05) 2408 (0x08) 2414 (0x0E) 2417 (0x11) 2432 (0x20) 2435 (0x23) Index 7 8 9 10 11 12 Internal PCB printed 0.45dBi 16 MHz Crystal + PLL 12 RF channel 2441 (0x29) 2444 (0x2C) 2462 (0x3E) 2465 (0x41) 2471 (0x47) 2474 (0x4A) 20dB channel bandwidth (Carson's rule) for modulated carrier Channel switching frequency range Modulation characteristics Transmitter aggregate data rate Effective radiated power If intermittent duty Transmission range Method of Frequency generation Range Power source Power consumption Nominal DC voltage Operating voltage Extreme test voltage (low) Applies cut off voltage (automatic switch off) DC maximum current Extreme Temperature range 2 MHz @ -20 dBm 2405 MHz - 2474 MHz Digital GFSK 2Mbits/s per second 0 dBi duty cycle:
