(the May, 2017 we investigation)

Surprising compact design fruit existing; is putting on, and feel fine!

From older model (WDC-867U3) of the same Wireless standard, we improve function, and large Dimensions falls.
22mm slight as for the part which jumps out even if we attach to note PC. We are not interested even if we carry with putting on.

Surprising compact design

"MU-MIMO" which is fast even if fast other cordless handsets are even plurally connected

As we plurally cope with concurrent communication process even if other cordless handsets are connected, communication is possible without waiting time.

※It is necessary for main phone to support MU-MIMO.

Placing is easy! Unnecessary troublesome driver installation (Windows 10)

Preparations for setup are completed just to put Windows 10 in Universal Serial Bus port. We set up CD drive, and troublesome work including driver downloading is available by unnecessary immediately.

Installation method is available to attached CD-ROM&WEB downloading environment!

We can choose installation method of driver among attached CD-ROM by ultra book (Ultrabook™) without drive of CD-ROM depending on downloading and use environment from WEB in environment where there is not Internet environment.

※Environment that can connect with the Internet by Wireless cordless handset embedding wired LAN or PC beforehand is necessary to download driver software.

Driver downloading of (8.1/7) where is for Windows from this
Driver downloading of (10.10-10.13) that is for Mac from this

We are easily connected by "pi, po, pa" one-button with WPS button

We input "encrypting key" into past setting by hand, and difficult work was necessary, but we only push button, and setting completes if there is between products corresponding to WPS.
As wireless LAN router of ELECOM supports WPS, wireless LAN can set even the first one in peace.

Connection simple in one-button! WPS button

Security capability that it is strong, and the latest coding standard "WPA2" deployment is high in

It supports "WPA2-PSK". You prevent takeover of line and leak of data and can use wireless LAN in peace.
