Enabling 4G support over the network
You can use PuTTY or the configuration update process to enable 4G support on 8000 Series clocks by copying the apn.txt file to the clock. The clock must be connected to the network to perform this configuration. You must obtain a SIM card and the APN information from your mobile service provider.
4G connectivity is enabled on the clock. The clock will use 4G
when a LAN or Wi-Fi connection is not available.
