Device-generated RF

Note: The module can cause

interference with other devices

such as hearing aids and on-

board speakers.

Wireless devices such as the

Mini Card transmit in bursts

(pulse transients) for set

durations (RF burst frequencies).

Hearing aids and speakers

convert these burst frequencies

into audible frequencies,

resulting in audible noise.

AllelectroniccomputingdevicesgenerateRFinterferencethat

•Displaypanelanddisplaydrivers

•Switching‐modepowersupplies
