 Wireless Symptom No wireless connection Audio or video interrupted or stops The WIRELESS indicator does not light Cause/Action  Make sure that the processor unit and the battery unit are turned on.  It may take a while before the image appears on the screen.  The radio waves become weakened or interrupted, depending on the distance or orientation of the processor unit and the battery unit, or an obstruction between the two units. Make the positions of the processor unit and the battery unit nearer (approximately 3 m or less), and orient the two units with their SONY logos facing each other. Wireless communication quality degrades if the panel with the SONY logo (the side with antenna installed) of the battery unit faces the floor, or away from the processor unit.  If wireless communication cannot be achieved successfully with the battery unit positioned flat, attach the supplied stand to the battery unit and adjust its orientation so that the SONY logo faces the processor unit (page 16).  Use the system where there are no obstructions between the processor unit and the battery unit.  There may be interference from other wireless devices. Turn off those devices and check if the phenomenon improves.  The transmission of audio and video signals, or the correct operation of the unit may be affected by interference if more than three wireless devices using the same frequency band (60 GHz), including this system, are used. 43
