B460IRR40P V1.0 Azden IRR-40P ‒ User & Installation Guide
Azden IRR-40P Soundfield
Troubleshooting:
If the IRR-40P does not operate as expected check the following:
Symptom
Probable cause/remedy
Main unit
No red indicator light
Unit unplugged, switched off or fuse blown
No green 'Signal' indicators
Transmitter unit not functioning ‒ check led
indicator on transmitter
Microphone transmitters
‒ all types unless specified
No light on transmitter
Batteries dead or incorrectly fitted
Alternating green/red light on
Swift
TX
pendant transmitter
Batteries need recharging
Red light on handheld transmitter
Batteries need recharging
Green light on transmitter
but no green light on wall unit
Receiver not receiving the IR signal
‒ Check that microphone emitters are not covered
or pointing into non-reflective area
‒ Check dome sensor is not obstructed and look for
red LED in centre. No red LED indicates no
connection between sensor and wall box so check
wiring on F-plug connectors
No red light on infra red sensor
Coaxial cable connections faulty or internal fault
caused by short circuit
Distorted, whistling and generally
nasty sound
Two transmitters on the same channel will cause this
‒ turn one off. Has your colleague from next door
come in wearing their transmitter?
Feedback whistling all the time or
when the user of the transmitter
speaks
‘Mic’ volume too high. Microphone too far away
from user's mouth
Sound too bright or boomy
Adjust the tone control to suit the acoustics of the
room and speakers
Sound distorted
Reduce the volume of the appropriate channel.
The system is only intended for speech and
music in an average size classroom giving up to
about 90dB SPL
Handy hint:
You can easily check if the transmitter emitters are working by pointing a
mobile phone camera at them ‒ you don’t need to take the photo but the emitters will
show up really clearly!
The camera will see the infra red light from the emitters.
