AC Power LED does not turn on.
Disconnect the power cord and remove the top cover. Check the main AC power fuse and
power cord. If the fuse is blown replace with same type and rating. Please contact SDI if
the fuse blows again or if the event that caused the fuse to blow is not known.
Monitor LED is off.
Check to see if the RF signal provided to the instrument is greater than +7 dBm.
Check to see if a signal is present at all outputs of the signal distribution module.
The Monitor LED will remain off with a power lever under +7dBm, but will still provide five
copies of the RF input signal. If the instrument is providing the copies of the input signal
you may continue using the HPDA-100RM-A.
If the power level of the RF signal provided is greater than +7dBm and the Monitor LED
remains off, the instrument will have to be returned for repair.
