Installing a 4G antenna 
Only the following routers support 4G antennas: 
•  RT-MSR810-LM 
•  RT-MSR810-LM-CNDE-SJK 
•  RT-MSR810-W-LM 
•  RT-MSR810-LM-HK 
•  RT-MSR810-W-LM-HK 
•  RT-MSR810-LM-GL 
•  RT-MSR810-W-LM-GL 
•  RT-MSR810-LME 
•  RT-MSR810-LMS 
•  RT-MSR810-LMS-EA 
•  RT-MSR810-LUS 
No 4G antenna is provided with the RT-MSR810-LME, RT-MSR810-LMS, and RT-MSR810-LUS 
routers. Purchase one yourself if required. 
To install a 4G antenna: 
1.  Change the angle of the antenna orientation from vertical to horizontal. 
2.  Attach the 4G antenna to the 4G antenna port on the router. Do not over-tighten the antenna 
to avoid damage. 
For better signal receiving, change the antenna orientation to vertical.
