2.3 Wireless Hardware Setup
The SRG-4858P features both a SIM Card and Mini Card slot for connecting to wireless
networks such as 4G. This section details how to install a SIM Card and 4G/LTE module
on the mini card slot.
2.3.1 Mini Card Installation
Step 1: Remove the six screws securing the top cover.
Step 2: Insert the 4G/LTE module into the Mini Card slot at an angle, then push down
gently and secure with a screw. Connect the coaxial cable to the 4G/LTE module.
Step 3: Replace the top cover and secure with the screws.
