The Network Unit (NU) should be placed where the existing cellular signal is best (generally by a high window). The unit requires at least one bar of signal to work. The Coverage Unit (CU) should be placed in the location you need improved signal. You can optimize coverage by moving the CU. The NU and CU communicate with each other wirelessly to provide the best signal improvement possible. Red and Green icons on the CU LED user interface will indicate whether the CU should be closer or further from the NU.
Mounting brackets and hardware are provided to mount either/both the Coverage Unit and the Network Unit. The brackets come equipped with screws and inserts for mounting in standard drywall.
The DUO+ comes with a 2-Year Warranty.
