Flexi Multiradio BTS RF Module and Remote Radio Head Description
WARNING!
Risk of electric shock!
Before turning RF power on, RF ports have to be terminated by nominal 50 Ω load (for
example, feeder with antenna). If these conditions are not met, do not remove the
plastic caps that are delivered within the unused RF ports. The plastic caps isolate RF
power from the environment, and thus provide electric shock security in case RF
power is accidentally on.
