as the installer user.
NO TICE
● When connecting to the SUN2000 directly from the mobile phone, keep the
mobile phone visible within 3 meters of the SUN2000 to ensure the
communication quality between the app and SUN2000. The distances are for
reference only and may vary with mobile phones and shielding conditions.
● When connecting the SUN2000 to the WLAN over a router, ensure that the
mobile phone and SUN2000 are in the WLAN coverage of the router and the
SUN2000 is connected to the router.
● The router supports WLAN (IEEE 802.11 b/g/n, 2.4 GHz) and the WLAN signal
reaches the SUN2000.
● The WPA, WPA2, or WPA/WPA2 encryption mode is recommended for routers.
Enterprise-level encryption is not supported (for example, public hotspots
requiring authentication such as airport WLAN). WEP and WPA TKIP are not
recommended because these two encryption modes have serious security
defects. If the access fails in WEP mode, log in to the router and change the
encryption mode of the router to WPA2 or WPA/WPA2.
