*1: The WPS feature is not available when WEP(64bit/128bit) or WPA-PSK(TKIP) is selected in Access Point Settings. If you wish to use the WPS feature, please select WPA2-PSK(AES) or disable wireless security.
*2: HTTP client. Proxy supported (for firmware version 1.05 or above for TR-7wf).
*3: Battery life varies depending upon multiple factors including frequency of communication, LAN environment, ambient temperature, recording interval, and battery performance. All estimates are based on operations carried out with a new battery and are in no way a guarantee of actual battery life.
*4: Approx. 10 days when Auto-upload Interval is 1 min, 1 yr when 1 hr, 1.5 yrs when 12 hrs or more.
*5: -10 to 45°C when using external power. (for TR-7nw)
*6: Software is not included in the package, but can be downloaded free of charge from the download page.
*7: For installation, it is necessary to have Administrator (Computer Administrator) rights.
