TROUBLESHOOTING
COMMON PROBLEMS AND SOLUTIONS
Most problems are related to low battery power. Use fully-charged batteries
in good condition.
BATTERY CHECK
• Confirm batteries are charged each night. A red light on the battery status light
indicates a low battery.
• Make sure the microphones obtain a full charge. A full charge takes 5-6 hours.
• When charging transmitter, ensure the red charging light turns on. The green light will
turn on when a full charge is reached.
PROBLEM: Low volume or feedback
SOLUTION: Follow these steps to eliminate low volume or feedback.
• Adjust the volume level on the microphone..
• Check microphone volume level on the amplifier. If the volume is too high, feedback
will occur. Adjust accordingly.
• Check input volume level on the amplifier. If the volume is too high, feedback will
occur. Adjust accordingly.
PROBLEM: No sound from speaker and wireless components
SOLUTION: Follow these steps to produce sound from amplifier.
• Confirm that the white POWER light located on the front panel of the amplifier is on.
• Confirm the microphone is powered on and linked to the amplifier. The mic 1 or 2
status light will be white on the microphone indicating the microphone is linked.
• Confirm that the microphone is turned on. There will be a solid blue light on the top
of microphone to indicate it is powered on and ready.
• Confirm that microphone is not muted. A solid white light on the top of microphone
will indicate it is muted.
• Check speaker connections on the amplifier. Make sure the cables are properly
connected (see page 31 of this manual for more information).
• Check volume level of amplifier. Make sure that the microphone volume level on
the 975 is not turned down all the way. Slowly turn up the volume level on the
microphone while talking into the microphone.
• If an Activate Station or Media Connector is paired with the 975, make sure that
the volume level of the Activate Station or Media Connector is not turned down
all the way. Slowly increase the volume level while talking into the microphone.

• Speak in a natural voice. A normal conversational speech level will provide an
adequate signal. It is not necessary to increase the intensity of your voice—the
audio system provides adequate amplification above ambient room noises.
• Avoid wearing jewelry that may rub or bump against the microphone.
• Mute the microphone during private conversations with a student, parent, or
other classroom visitor. You can tell the mic is muted when the light turns white.
• Recharge microphones each night. When recharged nightly, operating time
(actual usage) for the microphones will last through a typical school day.
