Problem Isolation Steps
that blue power LED on front of
RC2 is lit.
that the red LED above the corre-
sponding channel volume control
illuminates when speaking into
the microphone.
that the RC2 channel A & B
volume controls are set to just
below mid-range.
that sound from the "Audio In"
source can be heard.
the original microphone with a
known good system.
that the battery(ies) being used
in the microphone is charged
and is the proper type.
the original microphone with
another system that is working
properly.
whether a known good micro-
phone works with the RC2 being
tested.
if two microphones are being
used that they are on different
channels.
RC2 placement in the room.
that the RC2 is located away from
possible sources of IR interfer-
ence.
Resolution
If not, verify all connections are snug from the AC
connection to the power supply, and from the
power supply to the RC2. If all connections are
secure, determine if the outlet is working or test
with a known working power supply.
Verify that the frequency of the microphone
matches the frequency group of the RC2.
G1=microphone marked with"G1"
G2=microphone marked with "G2"
Adjust volume level to achieve desired loudness. If
still no sound, try connecting another audio device
to one of the inputs.
If the audio from a source can be heard, the micro-
phone is the most likely cause of the problem.
If the problem persists, the microphone is likely
the cause of the problem.
Install the proper NiMH battery(ies) that is fully
charged.
If static is heard with the known good system, the
microphone is likely the cause of the problem.
If the problem persists, the RC2 is likely the cause
of the problem.
If needed, change one microphone to the oppo-
site channel.
Evaluate the RC2 location in the room and adjust
as needed. It should be located near the center of
the room along a long wall. Avoid placing it near
obstructions.
Direct sunlight and Plasma monitors can adversely
affect performance.
