Proper Care and Handling
All Ettus Research products are individually tested before shipment. The CBX is guaranteed to be functional at the time it is received by the customer. Improper use or handling of the CBX can easily cause the device to become non-functional. Listed below are some examples of actions which can prevent damage to the unit:
- Never allow metal objects to touch the circuit board while powered.
- Always properly terminate the transmit port with an antenna or 50Ω load.
- Always handle the board with proper anti-static methods.
- Never allow the board to directly or indirectly come into contact with any voltage spikes.
- Never allow any water, or condensing moisture, to come into contact with the boards.
- Always use caution with FPGA, firmware, or software modifications.
