Frequently Asked Questions - STWM711 Skytec

How to install the microphone batteries?

Unscrew the battery compartment cover at the bottom of the microphone. Insert a 9V battery respecting the indicated polarity. Screw the cover back on. Turn the switch to ON to check operation.

What to do if the microphone does not turn on?

Check that the battery is correctly inserted and not discharged. If the low battery indicator lights up, replace the battery. Also ensure the switch is set to ON.

What is the maximum range of the system?

Under good conditions (no major obstacles or interference), the range can reach up to 50 meters. In normal use, expect about 30 meters.

Can I use two microphones at the same time?

Yes, this model is a dual channel system. You can use two microphones simultaneously without interference, each on its own channel (CHA and CHB).

How to reduce interference?

Avoid placing the receiver near other electronic devices, electromagnetic sources, or in corners. Fully extend the receiver antennas. Keep away from metal walls.

What does the low battery indicator mean?

The LED indicator on the microphone lights up when the battery voltage drops below a critical threshold. Replace the battery immediately to avoid signal loss or distortion.

How to clean the device?

Always unplug the receiver before cleaning. Use a damp cloth to wipe surfaces. Never use liquids, aerosols, or abrasive products.

Can I use other accessories?

It is recommended to use only accessories provided by the manufacturer to ensure compatibility and safety. Use of non-compliant accessories may damage the device.

What to do in case of a malfunction?

Do not attempt to repair the device yourself. Unplug it and contact a qualified technician or your dealer. Opening the casing may expose you to electric shock.

Where to recycle the device at end of life?

Do not throw the device or batteries in household waste. Dispose of them at an approved recycling center or return them to your dealer. The crossed-out wheelie bin symbol on the packaging reminds you of this.

USING GUIDE INSTRUCTION

OPERATION

• Put the receiver near the audio adjustor, connect with power and the signal protected cord with A.OUT, B.OUT or MIX.OUT. And then connect with the amplifier or the microphone of the audio adjustor (MIC IN). Draw out two antennas completely. Put on the power switch, The power indicator shines. This receiver is being standing by. (Don't put the receiver in a corner in order to work in a good condition)
• Unscrew the cover of battery case, install the battery correctly, then light it up. (There are labels on battery and battery case, don't install the battery oppositely)
• Put the switch to ON position. The signal lamp will shine at that time. the signal on the receiver available to the signal channel on. It means that the signal is available for the receiver from the microphone. Adjust the signal volume switch and the volume switch on the amplifier, keep this system a bit of volume. Speak to the microphone and output the signals.
• If the signal on the microphone is off or dusky, the battery is being low voltage. means that it needs to replace a new battery.

Notice

When the power pressure is lower than 7V, il may cause the instability of signal, the shorter effective distance and the timbre maybe not as good as normal, so please change new battery to avoid these.
