* The output power depends on filter duplexer losses. Complex duplexing may reduce the
power output.
**The squelch is set to -108 dBm, which ensures correct operation for most repeater system
scenarios. It will open approximately 3dB below the static sensitivity in the repeater cell thus
it will be open to any mobile on the cell border.
