Maintenance guidance of common faults
SCAN key-pressing:
press the key and the radio will scan the local radio station and save it automatically.
CH+ key-pressing:
press the key and the radio will read the saved radio station and select the next one in ascending order;
CH- key-pressing:
press the key and the radio will read the saved radio station and select the previous one in descending order;
Note:
MODE key is used to switch radio status in order to use radio key-pressing function; if the receiving frequency needs inputting manu-
ally, press the numbers on remote control directly to input the frequency of radio station.
•
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 ef-
fect.
•
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 interfer-
ence 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!
If there is still fault after the inspection above, please contact the nearest local maintenance department! The product technology
of our company is upgraded continuously and we will not inform of the change of product specification and function additionally!
