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 +7 dBm, 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 DA-1G.
If the power level of the RF signal provided is greater than +7 dBm and the Monitor LED
remains off, the instrument will have to be returned for repair.
