2. C omponent Verific ation and Explanation The first step when installing the repeater is to c hec k that all c omponents are present and that the parts do not have any visible faults. The figure below illustrates the items inc luded in the J uni J R20 Repeater Kit. F ig.
F ig. 3 Additional C overage Unit C omponents 2.1 DONOR UNIT(DU) The role of the Donor Unit is to c ommunic ate with the BTS . It is loc ated outside the building where servic e is to be improved. The Donor Unit c an be mounted onto a wall or a pole, depending on the spec ific installation needs. F ig.
2.2 C OVERAGE UNIT(C U) The role of the C overage Unit is to c ommunic ate with the mobiles within the building whic h needs improved c overage. It is intended for wall mounting. F ig. 5 C overage Unit (C U) 3. Preparing for Donor Unit and C overage Unit Installation Determining the proper installation loc ation for the Donor and C overage Units is very important, sinc e their position will determine the overall performanc e of the repeater.
4. BAND S ETTING Onc e the planning of the loc ation and positioning of the Donor and C overage Units is finalized, the authorized installer should proc eed with installing the Donor and C overage Units. But first, the installer should set the appropriate frequenc y band(s) for the repeater. The figure and table below show the DIP S witc h and the func tions for eac h sec tion. Usually both the PC S and C ellular bands have to be set up. After DIP S /W setting, turn power ON/OF F or DIP S /W 12# PIN ON/OFF.

Power C onnec tion and Optimization S ETTING 1) Onc e the RF C able is c onnec ted between the Donor Unit and Bias T and the sec ond RF C able is c onnec ted between the Bias T and the C overage Unit, the Power Adaptor should be c onnec ted to the Bias T. If the Power Adaptor is c onnec ted to Bias T before the RF c able is c onnec ted to either the Donor or C overage Unit, possible damage c ould oc c ur to the equipment.

Onc e power c onnec tion has been suc c essfully made (this c an be verified by c hec king the Alarm LED on the Donor Unit and LED indic ations on the C overage Unit, the Donor Unit azimuth should be positioned so that maximum signal level is being rec eived from the BTS . This c an be monitored via the LEDs whic h indic ate the signal strength reading (RS S I).

Appendix A. Produc t Introduc tion A.1 Overview The J uni J R- 20 MPE25K Repeater system is an RF repeater whic h provides c overage for indoor loc ations within a BTS c overage area. The repeater is intended to serve indoor loc ations where there is very little or no RF c overage. The system supports both US C ellular and US PC S bands. Verizon Wireless- authorized installation personnel are able selec t to frequenc y bands of operation via the internal band selec tion func tion.
The diagram below shows the basic system c onfiguration. Onc e the two supplied RF C ables are c onnec ted from the Bias- T to the Donor Unit and C overage Unit respec tively and the Power Adaptor is c onnec ted to the Bias T with AC Power turned on, the Donor Units and C overage Unit(s) will func tion properly.
