Troubleshooting and Technical Info
Please don’t discount hearing assistance in buildings, but rather check with staff to see that the system and devices are turned on and operating, much as wheelchair ramps need to be kept open. Any assistive listening will not work unless turned on.
If the system is turned on and there is no sound, contact a knowledgeable hearing loop installer for analysis.
Common Troubleshooting
Please see Hearing Loop Maintenance Guidelines by University of Virginia (UVA)
Probably the hearing loop is a perimeter loop and not a phased array. Contact a knowledgeable hearing loop installer.
With a hearing loop, there should be no delay (latency). Contact a knowledgeable hearing loop installer to analyze and solve the problem.
