& Specifications 1. Turn the ALD (Assistive Listening
Device) volume control on the
Media Connector front panel all
way the down.
2. Determine the size and type of
audio input jack on the device as
many manufacturers’ products
differ in connector size and shape.
The Lightspeed 370 Personal FM
System requires a 3.5mm to 3.5mm
patch cable (part# MMC3535).
3. Connect a patch cable from the
ALD’s microphone jack or AUX
input to the 3.5mm audio jack
labeled “ALD OUT” on the front of
the Media Connector.
4. Adjust the volume control on the
ALD’s receiver to maximum output.
NOTE: This is to set the maximum
allowable signal from
the Media Connector.
5. With the TOPCAT and ALD turned
on, speak into the REDMIKE VC
and slowly adjust the ALD
volume control until the
appropriate audio level is
attained in the ALD’s receiver
headphones.

All PROBlEmS : most problems are
related to low battery power.
SOlUTION: battery check
• Confirm the Power LED is blue.
• Confirm batteries are charged
each night.
• Confirm proper batteries are used.
The REDMIKE VC requires the
Lightspeed NH2A27 rechargeable
sensing battery for proper
charging. The REDMIKE Share
uses the NH2APK rechargeable
battery pack.
• Make sure the microphones are
turned off while charging so a full
charge is attained. Full charge will
last eight hours.
• Inspect the battery contacts. Clean
and adjust if necessary.
PROBlEm: hearing static
SOlUTION: follow these steps to
eliminate static.
• Ensure sensor is in optimum
location (refer to sensor placement
in Installation Guide). A single
sensor will cover a 1600 sq. ft. (150
sq. meters) enclosed classroom
with a ceiling height of 12 ft. (3.5
m) or less.
• Ensure that no other REDMIKE
VC/REDMIKE Share is operating
on the same channel. Check the
channel switch setting on the
back of the REDMIKE VC or in
the battery compartment of the
REDMIKE Share.
PROBlEm: low volume or feedback
SOlUTION:
follow these steps to
eliminate low volume or feedback.
• Ensure microphone is positioned
appropriately, just below the collar
bone.
• Check volume level on the
REDMIKE VC. If the volume is too
high, feedback will occur. Adjust
accordingly.
PROBlEm: no sound from speaker
SOlUTION: Follow these steps to
produce sound from speakers.
• Turn the Media Connector on.
Confirm that the POWER light
located on the top panel switch
is on.
• Confirm signal is being received
at the ISR on the TOPCAT. The IR
signal light will be red (green for
channel B) indicating a signal is
being received.
• Confirm that REDMIKE VC is
turned on. There will be a blue
LED on the microphone to indicate
it is powered on.
Note: Most problems are directly related to low battery power. Please run
through the “Battery Check” items first. For remaining troubleshooting, use
known good, fully-charged batteries.
