MODIFICATION USER INSTRUCTIONS
ZTE MC888, PRO, Ultra 5G Router Modification Instructions
Warranty Notes
- This modification voids all warranty rights with the manufacturer and therefore shall not be returnable under warranty to the manufacturer.
- Do not open the unit once modified; doing so may damage the new antenna outputs. Any attempt to open the unit causing damage to the outputs will be a chargeable repair.
Antenna Notes
- Please note this modification has converted the internal antennas to external antennas.
- The internal antennas are no longer functional as they are now converted for external antenna use.
5G SA/NSA Explained
- SA (Stand-Alone): The mast and router are capable of negotiating a link without needing a 4G connection first. The router must be SA capable, and the mast must have its own dedicated 5G infrastructure “SA” not dependent on 4G.
- NSA (None Stand-Alone): The router and the mast must negotiate a 4G link before it can establish its 5G link. Once connected to 5G, it will still require the 4G link to maintain the 5G connection.
Software Configuration
- There have been no firmware/software adaptations to the router during the modification process.
- During testing of the modification, the router will have been restored to factory default settings; any settings that were previously on the unit have been lost.
- (If your unit has factory antenna outputs) Please ensure within the router login page, you have selected "use internal antenna". This ensures the use of the modified antenna outputs. (Some routers do not have this option available).
Port Frequency Band Ranges
(Please refer to the router's specifications and your local network band support list for compatibility)
