Troubleshooting & Servicing

Do not attempt to modify the device in anyway. Doing so could invalidate your warranty.
PROBLEM & ITEMS TO CHECK
UNIT WILL NOT TURN ON
• Is unit plugged in?
• Are batteries charged?
UNIT OPERATES ON AC BUT NOT BATTERY
•
Charge battery

Replace battery
`
SOUND IS MUFFLED
•
Tone too low
FEEDBACK: A LOUD SQUEALING, SHRILL OR HOWLING
SOUND THAT IS SELF GENERATED
•
Feedback occurs when a microphone is too close to the
speaker or the microphone volume is too high, or the
microphone is pointed towards the speaker. It is also caused
by sound reflecting off hard surfaces.
•
Reduce or eliminate Feedback by
- Pointing the microphone in a different direction
- Keeping the microphone BEHIND the speakers
- Turn down the volume levels
POWER IS ON, BUT NO SOUND
•
Check main volume level.
•
If using wireless, be sure receiver and transmitter battery is
installed and both units are turned on.
MICROPHONE SIGNAL IS WEAK
•
If microphone has batteries, check batteries.
•
Check cables/connectors.
WIRELESS MIC DOES NOT WORK
•
Check that transmitter batteries are fully charged and ensure
transmitter is on.
•
Does green "signal" LED light when transmitter is turned on?
•
Are the transmitter and receiver on the same channel? (1-16)
WIRELESS MIC CUTS IN AND OUT
•
Is unit visible (line of sight) from user? If not, move unit into
view when using wireless microphone.
•
Does the green "signal" LED on receiver goes out when sig-
nal drops out? Check batteries in Microphone transmitter.
•
Distance is not very far. On receiver, turn mute level counter
clockwise as far as it can go (minimum level).
BATTERY WILL NOT HOLD CHARGE
•
Replace Main Batteries every 1-2 years if unit is not left
charging when not in use.

plugged into the AC outlet for several hours. After a
year or two the battery may need to be replaced. Bat-
