TROUBLESHOOTING
The iC2 System is a configurable system (i.e., the product arrives “empty” and must be
programmed by the installer). Troubleshooting generally occurs after the iC2 is programmed;
however, the iC2 System can be divided into two main areas, and some troubleshooting can occur
prior to programming:
1) Hardware Issues
2) Programming
(refer to the Niles QuickConfig Configuration Software Manual for more
information on programming troubleshooting)
HARDWARE ISSUES
There are three basic issues that can prevent proper operation of the iC2 system. These issues are
presented in the order of probability and are as follows:
PROBLEM:
1. Bad Connections or Wiring
If the connections or wiring are wrong, loose, shorted or open, the system will not
operate properly. The symptoms could include: Power LED flickers or is off, IR/RF Test
LED is continuously flickering or on without any iC2 remote use, intermittent operation
or no operation.
SOLUTIONS:
• Test your power supply connections
• Test your Flasher connections
• Test your Sensor connection
• Test your cable for shorts and opens
2. RF or Electromagnetic Interference
Digital sources, poorly shielded sources, cordless telephones, cell phones, high-
definition television sets, light dimming controls and other sources of electromagnetic
fields can induce radio frequency noise and interference into your home theater
automation system. The symptoms could include:
Flashback LEDs on IR/RF Tester continuously flickering or
on without any iC2 remote use, poor range, intermittent
operation or no operation.
The Niles IR/RF Tester (stock number FG00727) is a
troubleshooting tool to aid in diagnosing hardware issues
with the iC2 System (
Figure 22
). It is not required for
operation and, therefore, is sold separately. The IR/RF
Tester has two LEDs (one red, one green) and can be
plugged into IR Output ports to diagnose whether or not
the HT-MSU is issuing IR codes out of individual ports.
