TROUBLE SHOOTING
Please take time to read this manual before asking after service
and check following points. If it contains unusual things please
contact your purchasing store. They will be happy to help you.
1. Before connecting and operating the unit, check that the
voltage setting is conform the voltage available in your area.
2. If the LED indicator lights on it means that the power supply
needs to be replaced. Please replace with new 9 V battery and
make sure the polarity (+)(-) of the battery is connected
properly.
3. Signal dropouts and noise may suddenly be encountered by
interruption from outside, too much distance between
microphone and receiver or low power of the battery.
In such case, adjust receiver antenna or replace battery.
4. Do not drop the microphone on a hard concrete floor,
nor strike the microphone head front with a fist or fingers,
nor blow/breath heavily into the microphone head front.
5. Take out the battery when not used for a long time. This will
prevent damage that a defective ‘leaking’ battery may cause.
