the router name or password are changed, the WiFi dongle will need to be reconfigured.
For details, please refer to the [QUICK INSTALLATION GUIDE] which is attached to the
accessory bag.
3. If DHCP is enabled on the router, the LAN version module does not need to be
configured. Otherwise, please refer to the [QUICK INSTALLATION GUIDE] which is
attached to the accessory bag.

Do not touch the waterproof plug in the card slot except for replacing the SIM card.
In that case, please make sure the card slot is completely sealed by the weatherproof
plug after replacing the SIM card. Any damages caused by improper waterproof plug
placement, will void warranty.
