If the transmission rate drops, the connection is lost, or other problems 
occur when using the wireless functions, try the following corrective actions.



When using indoors, install the device in the room where you are 
using the camera.



Install the device where people or objects do not come between 
the device and the camera.

If the transmission rate of a wireless LAN drops because of the 
influence of the following electronic devices, stop using them or move 
further away from the devices to transmit communication.



The camera communicates over wireless LANs via IEEE 802.11b/ 
g/n using radio waves in the 2.4 GHz band. For this reason, the 
wireless LAN transmission rate may drop if there are Bluetooth 
devices, microwave ovens, cordless telephones, microphones, 
smartphones, other cameras, or similar devices operating on the 
same frequency band nearby.



When connecting multiple cameras to one access point, make 
sure the cameras’ IP addresses are different.



When multiple cameras are connected to one access point, the 
transmission rate drops.



When there are multiple IEEE 802.11b/g/n (2.4 GHz band) access 
points, leave a gap of four channels between each wireless LAN 
channel to reduce radio wave interference. For example, use 
channels 1, 6, and 11, channels 2 and 7, or channels 3 and 8.



When [Wi-Fi/NFC] is set to [Enable], image transfer using an Eye-
Fi card is disabled.
