Access Base
(RCA, TCA,
955, AL)
No sound from
speaker
Check that blue power light on front of
Access Base is on.
If not, verify all connections are snug from the AC
connection to the power supply, and from the
power supply to the Access Base. If all connec-
tions are secure, determine if the outlet is working
or test with a known working power supply.
Check that the microphone is linked to
the Access Base.
The mic 1 or mic 2 status light will be green on
the front of the Access Base indicating the micro-
phone is linked.
Check system ID tags to verify that the
components being used have
been registered together.
If necessary, re-register system components.
Verify that the microphone is turned on. There will be a solid blue light on the microphone
to indicate it is powered on and ready.
Verify that microphone is not muted. A solid red light on mic 1 or mic 2 will indicate it is
muted.
Verify that sound from the Access Base
“Audio In” source can be heard.
If the audio from a source can be heard, the micro-
phone is the most likely cause of the problem.
Check microphone volume level on Ac-
cess Base or Media Connector
Ensure that the volume level is not set too low.
Feedback Check that the volume on the Access
Base or Media Connector is not
set too high.
Reduce volume as needed until feedback issue is
resolved. Remember the teacher should barely be
able to hear his/her own voice at optimum volume
levels.
Check that the tone is set to the mid-
point.
Set the tone indicator to the mid position and
then adjust as needed to eliminate feedback.
Low volume Check that the Microphone Volume
level on the Access Base or Me-
dia Connector is not set too low.
Position the volume indicator at the mid position
and then adjust as needed for normal operation.
Adjust volume level on the Flexmike. Adjust as needed for normal operation.
Drop-out /
intermittent
operation
Verify there is a solid link light on the
Access Base.
The Access Base will operate in rooms up to 2500
square feet. Substitute known good microphone
and see if intermittent operation stops. If it does,
the original microphone could be the source of
the problem.
