To customers: Respectable users, Thank you for your support and trust on purchasing the products of our company. To fully exert the function of the product, we suggest you to read the operating instruction carefully before using it, for the convenience of grasping the connection method and using points. Please take care of the operating instruction after reading it for the purpose of further reference.Product features  Ultra-low distortion amplifying circuit Digital karaoke, treble and bass independent adjustment Built-in MP3 encoding supporting U disk Unique acoustic appearance design Professional treble and bass gain controlling circuitBuilt-in battery for outdoor activities Built-in professional wireless microphone systemProfessional high-effective loud-speaking unit Compatible to DVD/VCD/PC and other sound sourcesSuitable for adaptor and charging Intelligent power switch charging circuitAttention The product has been installed with battery, making it applicable to the outdoor singing, advertisement, recreation and other activities. Please charge the battery before using it outdoors, so as to guarantee that the machine can be used for a longer time outdoors. The machine has been set with power switch circuit. When you connect the adaptor to the power and insert the plug to the charging interface, the machine will switch to the power supplied by the adaptor automatically and charge the built-in battery. When the adaptor interrupts the power, the machine will intelligently switch to the built-in battery for work continuously. When adaptor is used to charge the battery, the integrated intelligent charging circuit within the machine will give hints about charging and the charging indicator lamp will light. After charging is finished, the intelligent charging circuit will give hint to that that the charge has been fully charged and light the charging indicator lamp. At this moment you can close the AC power of the adaptor. If you still use adaptor in the machine to work, the charging circuit will automatically cut off the charging circuit and it is unnecessary for you to worry about the charging breaking. You shall notice that the battery 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. With more charging times, the battery volume will change and full charging time will reduce 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 electricity quantity of the battery is reduced when using the machine outdoors, please close the power switch on the rear plate and charge the built-in battery within 24hours. If the electricity quantity of battery is totally consumed, the situation that the battery can not be charged and the service life is expired will happen. When you don’t use the machine for a long time and leave it alone, please charge the battery every six months, so as to avoid the invalidity of battery. Panel/rear plate/MP3 function and operation When you need to use the built-in MP3 encoding function, please format your USD disk (U disk for short below) as FA-T32 format in computer first and then copy the file in MP3 format in U disk. When reading U disk, the encoding system will engage in encoding playing according to the generation sequence of MP3 songs file. Therefore, the song which is copied to U disk first will be played in priority or vice versa. When the user needs to play according to the specific sequence, they can arrange the copying sequence. If the files copied to U disk can not be played, please inspect whether the file format is in MP3 format. If not, please switch to MP3 format in computer and then copy to U disk in order to play normally. When copying MP3 file, you shall copy to the catalogue of U disk. It is suggested to delete all the unnecessary files and file catalogues in order to reduce the occurrence of reading error when the encoding is played. When the user buys U disk, please select the ones with better quality and internal encoding supporting 64MB/128MB/256MB/512MB/1GB/2GB/4GB/8GB and other volumes. During the playing process, please make it far away from the places with high temperature, high magnetic field and high frequency interference.

Operating Instructions Please carefully read the operating instruction before using our product Basic operation and attention of wireless microphone  Open the battery box correctly and install the battery. Attention shall be paid to the cathode and anode of the battery.Turn the power switch on microphone to “ON”. If the power indicator lamp does not flash or always lights, inspect whether the battery voltage is insufficient or the polarity of battery is installed oppositely. Before using wireless microphone, please extend the rod antenna and make it vertically upward, so as to reach a better receiving effect.Adjust the microphone volume knob on the audio amplifier and adjust its position according 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, you can put the microphone switch in mute status; once using is stopped, you can turn the microphone switch in off status. The microphone will pick up sound to amplify it and input 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 other obstacles; 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 use it beyond the effective range in order not to affect the singing effect; when the electricity quantity of battery is reduced or the wireless interference signal of the using environment is too strong, the using distance shall be shortened accordingly.To reach the best singing effect, the distance between mouth and microphone shall be 5-15CM and the best angle is 45degrees. After the microphone is used for a very long time and lacks of electricity, the indicator lamp for electricity insufficiency will light. Please timely change the battery in order not to affect the singing effect.Please never use the microphone in the same frequency point for singing within short distance since it may cause silence or interference noise. If you have purchased more than two sets of active audio amplifiers matched with wireless microphone from the company and intend to use them together, please select the varieties in different standard frequencies. If the frequency is identical, two sets machines can not be used until they are separated from each other for 100m, so as to avoid mutual interference and other unnecessary troubles! Never get the machine to VCD/CD/DVD and other equipments with strong interference frequency when they are used, so as to avoid mutual interference between the same frequency and directly affecting the normal work of wireless receiving of microphone!Maintenance guidance of common faultsCommon simple faults and guidance for operation and repair Fault phenomenonFailing to electrify No sound External microphone has no sound Problems with wireless microphone Simple fault analysisThe power switch is not opened The electricity quantity of built-in battery is totally consumed Failing to input sound source Failing to establish signal line Main volume is switched to minimum U disk playing has no sound Faults with external signal source Poor contact or damage of external signal line External microphone is not fully inserted in the jack The external microphone switch is not opened The volume knob of microphone is off The switch of wireless microphone is not opened The wireless microphone is not inserted in the battery The sound of wireless microphone is in distortion TroubleshootingOpen power switch Use power adaptor to charge the battery Change signal source Reconnect signal line Properly adjust the volume knob Inspect U disk or audio switch Change signal source Readjust or change signal line Totally insert the microphone to the jack Open the switch of wireless microphone Properly adjust the volume knob of microphone Open the switch of wireless microphone Insert electrical apparatus to the battery box of wireless microphone Change the battery of wireless microphone If there is still fault after the inspection above, please contact the nearest local maintenance department!
