Special Notes & Troubleshooting Guide

Note On Unit Installation
1. For best sound projection unit should be placed on raised surface or tripod 4-6
feet above the oor.
2. When turning on the system initially, volume should be set to lowest settings,
and raised as needed.
3. The battery charge light will blink green when the batteries are charging, but
will remain steady once fully charged.
4. If there is poor wireless microphone reception (crackling, buzzing or cutting in
and out), change the channels on the main unit and wireless microphone to one
of the other available 16 channels. There may be interference on the channel
your operating on. It is also a likely possibility that the microphone’s batteries
need recharged/replaced if wireless signal is weak.
5. If adding your own external speaker, the requirements are 4Ω/80W. Failure to
meet these requirements may result in poor audio, or excessive feedback.
Troubleshooting Guide
1. Make sure battery’s positive side faces up when changing the remote control
batteries, and observe the correct insertion direction (positive/negative) for the
system’s and microphone’s rechargeable batteries before calling for support.
2. Turn unit o while not in use and remove batteries if unit is to be left unused for
a long period of time.
3. Operating time depends on volume. When the green signal is steady (not ash-
ing) battery is fully charged. If indicator is ashing unit can receive charge. If
charge is very low the indicator will remain o . Please recharge as soon as pos-
sible. You may need to plug into external power source at this point.
4. To keep batteries in optimal condition, please charge once every 2-3 months.
Note on Unit:
1. Do not open this unit, or alter its components in any way. Doing so voids your
warranty, and can result in electrocution or unit damage. You alone are liable if
anything occurs when servicing the unit yourself.
2. Be careful not to drop or jar the unit severely. Damage may occur, and this type
of abuse is not covered by the warranty.
3. Do not leave the unit exposed to the heat and direct sunlight for prolonged
periods of time. Heat may damage the unit.
4. Do not use wheels in mud, stone or poor ground conditions to avoid any dam-
age to wheel assembly.
