While the system is running on AC power, tempo- 
rarily remove the grounding wire to determine if it 
is the source of the RFUBMI. See page 3-19 for 
proper grounding requirements. 
If an external battery back-up power source is in- 
stalled, switch system operation to battery back-up 
power by unplugging the power source’s AC pow- 
er cord (with grounding wire connected to equip- 
ment cabinet). If RFI/BMI stops, the AC power 
source is the cause. Install an RFI/BMI filter or 
equivalent on the AC outlet. 
NOTE: For further RFI/BMI troubleshooting assistance while on sire, technicians should contact Customer Support 
with the following information:
