Configuration of xbee router with available pan

i know that if pan id of xbee is not set then when xbee is power on then it automatically connected with nearest xbee network.but my problem is that i have p1 network with c1 coordinator and 1 router R1 and another router R2 with default panid so it is not in any network.I want to put R2 at that place where it is in range of R1 but it is out of range of we i power up R2 then i should find P1 network and automatically assigned itself with panid of P1 but it failed to configure itself so how i can add r2 router in P1 network.
channel verfication is on in router
NJ also enable in Coordinator

i explain all that in photo also which is in following link

What is the NJ time set to on R1?
