P a g e 3 The FCC Wants You to know NOTE: 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. FCC Warning Changes or modifications to this equipment not expressly approved by the party responsible for compliance (SCR Engineers Ltd.) could void the user’s authority to operate the equipment LD Module FCC ID: AMUBUM Manufacturer: SCR Engineers Ltd. 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.

P a g e 5 2 LD Module of BU-500 LD Module FCC ID: AMUBUM RF Transceiver: Atmel AT86RF233 RF Frequency: 2.405-2.48GHz Modulation type: QPSK RF Channels: 5Mhz separation,16 ch Baud Rate: 250K Bit/Sec (Not configurable) RF Module output power: 0dBm maximum Operating voltage:- from limited 5VDC supply from BU500/E main board. The unit design as specific design for BU500/E. Two Modules assembled on BU500 Antenna and by flat cable to BU500 main board BU-500/E (Base Unit) is a unit used to collect messages from tags and send them to central management system. The unit replies to each tag upon receiving a message. They unit is also used to set various tag parameters. 2.1 BU-500 Units contains Internal Antenna Internal Antenna type: Two polarizations, internal diversity patch directional Vertical and Horizontal Antenna gain: 10dBi Maximum gain. Average RF data: 3 messages/hour, 3mSec/message, ~30bytes/message per tag.
P a g e 6 2.2 LD Module Options Option 1 (not in use): Direct assembly on BU-500 board with connection to antenna by coax cable. Option 2: Direct assembly on the antenna with connection to BU-500 board by flat cable
