Please charge the batterybefore using it outdoors, so as to guarantee that the machine can be used for a longertime outdoors. The machine has been set with power switch circuit. When youconnect the adaptor to the power and insert the plug to the charging interface, themachine will switch to the power supplied by the adaptor automatically and chargethe built-in battery. When the adaptor interrupts the power, the machine willintelligently switch to the built-in battery for work continuously. When adaptor is usedto charge the battery, the integrated intelligent charging circuit within the machinewill give hints about charging and the charging indicator lamp will light. Aftercharging is finished, the intelligent charging circuit will give hint to that that thecharge has been fully charged and light the charging indicator lamp. At this momentyou can close the AC power of the adaptor. If you still use adaptor in the machine towork, the charging circuit will automatically cut off the charging circuit and it isunnecessary for you to worry about the charging breaking. You shall notice that thebattery has certain service life and it is beyond the warranty scope of the company.Under general circumstances, the built-in battery needs charging 8-10 hours. Withmore charging times, the battery volume will change and full charging time willreduce accordingly. When the battery is out of charge after being used for a short time,please change the built-in battery. The user shall also notice that if the electricityquantity of the battery is reduced when using the machine outdoors, please close thepower switch on the rear plate and charge the built-in battery within 24hours.

Basic operation and attention of wireless microphone● Open the battery box correctly and install the battery. Attention shall be paid to thecathode and anode of the battery.● Turn the power switch on microphone to “ON”. If the power indicator lamp doesnot flash or always lights, inspect whether the battery voltage is insufficient or thepolarity of battery is installed oppositely.● Before using wireless microphone, please extend the rod antenna and make itvertically upward, so as to reach a better receiving effect.● Adjust the microphone volume knob on the audio amplifier and adjust its positionaccording to the sound volume when singing, so as to reach the ideal effect.● If you have to use wireless microphone temporarily during the singing process, youcan put the microphone switch in mute status; once using is stopped, you can turn themicrophone switch in off status. The microphone will pick up sound to amplify it andinput to the horn of the audio amplifier no matter it is in mute or off status.● The receiving antenna shall not get access to the metal surface, wall or otherobstacles; if it is too closed to them, the performance will be reduced dramatically,influencing the receiving effect.● The effective using distance of wireless microphone is within 30m, please never useit beyond the effective range in order not to affect the singing effect; when theelectricity quantity of battery is reduced or the wireless interference signal of theusing environment is too strong, the using distance shall be shortened accordingly.● To reach the best singing effect, the distance between mouth and microphone shallbe 5-15CM and the best angle is 45degrees.● After the microphone is used for a very long time and lacks of electricity, theindicator lamp for electricity insufficiency will light. Please timely change the batteryin order not to affect the singing effect.● Please never use the microphone in the same frequency point for singing withinshort distance since it may cause silence or interference noise.● If you have purchased more than two sets of active audio amplifiers matched withwireless microphone from the company and intend to use them together, please selectthe varieties in different standard frequencies. If the frequency is identical, two setsmachines can not be used until they are separated from each other for 100m, so as toavoid mutual interference and other unnecessary troubles! Never get the machine toVCD/CD/DVD and other equipments with strong interference frequency when theyare used, so as to avoid mutual interference between the same frequency and directlyaffecting the normal work of wireless receiving of microphone!Maintenance guidance of common faultsCommon simple faults and guidance for operation and repairFault phenomenonSimple fault analysisTroubleshootingFailing to electrifyThe power switch is notopenedThe electricity quantity ofbuilt-in battery is totallyOpen power switchUse power adaptor tocharge the battery
