Appendix A: Manually Reducing the Uplink Gain
If excessive noise is received in the BTS uplink receiver during repeater use, the
repeater uplink signal may be too strong. Up to 6 dB attenuation of the repeater UL
signal may be inserted by toggling switches 1 and 2 according to the table below
.
Note: This manual control overrides the automatic set-up software. It also
unbalances the UL gain relative to the DL gain.
