4 Operation
To begin operation, please review the steps outlined in Sec. 2 Quick Start.
Please Note: In compliance with 47 CFR 15.519(a)(1) the wireless dongle and /or hub will
cease transmission within 10 seconds unless it receives an acknowledgement from the
other that its transmission is being received. An acknowledgment of reception must
continue to be received by the wireless dongle and / or hub at least every 10 seconds or
the UWB device will cease transmitting until it receives acknowledgement. This may
cause some additional delay in operation when first associating the dongle and hub if
hub is out of range of dongle or power is applied to hub after 10 seconds of dongle
connection.
