HDR-AX2000 2-way radio Anomaly

My HDR-AX2000 loses focus and exhibits other bizarre behavior when a professional 2-way radio is in use within up to 3-4 feet of the camera. This problem can be reproduced. My interaction with Sony Chat Support says this is normal operation due to the "magnetic field". My Panasonic AG-AC130 and Sony VX2000, VX2100, PD150, PD170, DSR250, TRV900 cameras do not exhibit this behavior. Anyone else seen this?
