6. Switch Function

(1) WPS switch
The WPS switch is used for pairing the Wi-Fi interface with the access point. There are two types
of WPS: push button configuration (WPS-Push) and PIN code method (WPS-PIN).
● WPS-Push
Hold down the WPS switch for 2 seconds to start WPS-Push pairing.
When WPS-Push is enabled on the Wi-Fi interface, LED1 starts flashing green (0.5-sec interval)
and the pairing can be completed by enabling WPS-Push on the access point.
● WPS-PIN
Hold down the WPS switch for 15 seconds to starts WPS-PIN pairing.
When WPS-PIN is enabled on the Wi-Fi interface, LED1 starts flashing green (0.2-sec interval)
and the pairing can be completed by enabling WPS-PIN on the access point.
Before using WPS-PIN, the PIN code of the Wi-Fi interface needs to be set on the access point.
This product is only compatible with the access point that supports WPS.
(2) RESET switch
● Hold down the RESET switch for 2 seconds to reboot the system.
● Hold down the RESET switch for 15 seconds to initialize the Wi-Fi interface to the factory default.
When the Wi-Fi interface is reset to the factory default, ALL the configuration information will
be lost. Take great care in implementing this operation.
