Once the HBE is powered up and all alarms have cleared, the operator can place the HB 

repeater in broadcast mode as follows: 
 

1.  Set SysPowerSetp to the site specific power level (max. 53.0 dBm) – see Figure 4-4, 

config  window  line  4.    SysPowerSetp  is  used to set the power level for the HB RF 

signal.
