LED Indicators
One Internet status indicator
White: Connected to the Internet.
Red: No SIM card is inserted or detected, or the SIM card has
insufficient balance.
One Wi-Fi indicator
On: Wi-Fi is enabled.
Flash slowly: A pairable HiLink device is detected.
Flash quickly: HiLink pairing is in progress/WPS connection is in
progress.
Off: Wi-Fi is disabled.
The indicator starts to flash slowly only when B535-232a
detects a new HiLink device.
One group of signal strength indicators
Signal reception available (more indicators mean better
reception).
Buttons
One Power ON/OFF switch
One H button
The Wi-Fi indicator flashes slowly when the router detects a
HiLink device. Press the H button to connect the HiLink
device to the router's Wi-Fi.
When the Wi-Fi indicator is steady on, press the H button to
enable WPS.
