System will not power “ON”
Verify AC power; the power button will illuminate Blue when turned ON
Check if system has been unplugged; reconnect to power outlet or
use another device to ascertain power available at outlet
Check circuit breaker
Call maintenance for assistance
System is turned “ON” but there
is no sound
or
System is in standby and does
not “wake up”
Turn “ON” microphone/ transmitter; the power button will illuminate to
solid Blue when turned ON
If the power button is illuminated red, the battery is low
Ensure the mic is not muted (blinking blue light on mic indicates it is
muted)
Ensure gain/volume control knob on amplifier/receiver is turned up to
mid-scale (12 o’clock position)
On amplifier/receiver, ensure a green LED is illuminated just below Ch
A or Ch B knob (depending on the microphone used).
If no LED is illuminated:
•
Check the green LED on the ceiling sensor
If sensor LED is not lit:
•
Sensor has been disconnected (check cable plug ends), or
•
Power output to sensor has failed (Sensor or amplifier may need
to be
replaced)
Voice is distorted and/or signal
drop-out occurs
Verify that the sensor is not being covered
Verify there is no obstruction between microphone and sensor
Ensure there is no direct sunlight on sensor
Ensure no other IR mics in room are turned on
If sensor is mounted on a dark surface or without a flush ceiling
surface, reception can be hampered.
