measures. 
- Please make the wireless LAN connection device close to the projector . 
-   Place away from devices that can emit electromagnetic radiation, such as microwave ovens, game machines. Do not use 
these devices if you are still unable to solve the problem.
- If multiple wireless devices are connected with the same router , the bandwidth will be insufficient.
-   Please prevent from using the projector in a location prone to static electricity , such as on a carpet.
 
f If it happens that the wireless LAN connection is cut off unexpectedly, please set [WIRELESS LAN] in the [NETWORK/

f Is [MEMORY VIEWER] or [Panasonic APPLICATION] selected in [CONNECTION LOCK] menu?  
Please change the setting.
 
f Please check the setting of the Intel
® WiDi / Intel® Pro WiDi / Miracast compatible device. For details about the connection 
method of MIRRORING, refer to the Operating Instructions of the Intel® WiDi / Intel® Pro WiDi / Miracast compatible device.
 
f Are there any obstacles between the Intel® WiDi / Intel® Pro WiDi / Miracast compatible device and the projector? In 
addition, is the Intel® WiDi / Intel® Pro WiDi / Miracast compatible device far from the projector?  
Please remove the obstacles or make the Intel® WiDi / Intel® Pro WiDi / Miracast compatible device close to the projector.
 
f The column "Paired devices" will remain the connection information such as the Intel® WiDi / Intel® Pro WiDi / Miracast 
compatible device etc., but you cannot reconnect with the screen, please\
 connect with the devices that can be connected 
from the list.
 
f Cancel the sleep state or switch the log-on user of the Intel
® WiDi / Intel® Pro WiDi / Miracast compatible device, the

f Since MIRRORING is connected wirelessly, the picture or sound may be distorted by the radio wave environment. In such 
cases, please try the following measures.  
- Please make the Intel
® WiDi / Intel® Pro WiDi / Miracast compatible device close to the projector. 
-   Place away from devices that can emit electromagnetic radiation, such as microwave ovens, game machines. Do not use 
these devices if you are still unable to solve the problem.
- If multiple wireless devices are connected with the same router , the bandwidth will be insufficient.
 
f If there is a problem with the content itself, the picture may be distorted, please confirm the content.
 
f The picture or sound of MIRRORING is distorted depending on the Intel
® WiDi / Intel® Pro WiDi / Miracast compatible 
device. It may be caused by the processing capability and the wireless t\
ransmission performance of the Intel® WiDi / Intel® 
Pro WiDi / Miracast compatible device, and it is not a malfunction of the projector .
The connection of MIRRORING will be interrupted if there is no operation\
 after connecting with the MIRRORING.  
f Depending on the configuration of your Intel
® WiDi / Intel® Pro WiDi / Miracast compatible device, the connection may be 
lost in some time. Please check the saving power setting of the device.
 
f The problem will be improved by updating the wireless driver and firmware. Please contact with the manufacturer for the 
technical support about the device.
