Proper Care and Handling

All Ettus Research products are individually tested before shipment. The LFTX/LFRX is guaranteed to be functional at the time it is received by the customer. Improper use or handling of the LFTX/LFRX 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.

	Never apply more than +10 dBm of power into any RF input.
	Always use at least 30dB attenuation if operating in loopback configuration
