Common faults

When the power is turned on,the display does not light:
Is the power cable is correctly plugged in?
Is there power at the power socket?
*Is the fuse blown?(Remove power before checking!)
When you speak into the microphone ,and the RF power is showing correctly ,but there is nonsound output:
Check the transmitter or receiver output volume controls are turned up?
Check the audio output and microphone cables are connected correctly?
Signals are only detected are shortrange between the transmitter and receiver.
Check antennas are correctly connected and are for the correct frequency-band?
Are the receiver batteries OK?
*Are there other strong RF transmissions in your location?
Audio quality is poor:
Are the receiver batteries OK?
Are there other strong RF transmissions in your location?
*Is there another nearby microphone system on the same channel? (Separate same-channel systems by at least 100m,or use other frequencies.) 10 3
Momentary loss of sound as microphone(s) removed throughout the operating range.

Reposition the receiver, perform a “walkthrough” and observe the signal strengths. If audio dropouts persist, mark these“ dead spots” in the operating area and avoid them during the performance.

Operations Of Receiver

Open the battery cover, insert 2 *AA 1.5V batteries into the receiver battery compartment, turn on there ceiler power, the LCD display will be ON ,it is showing the frequency and battery level (BAT ),
check the receiver frequency is the same as the transmitter ,and the battery voltage ,if the low bat indicator long lighting ,and corresponding LCD display BAT under 2 segments ,it is the low voltage ,please replace them with the new batteries
The receiver include Voice gain adjusting device can be follow each person sound.
AF output selective switch .According the use of AF output signal to select the line output(high impedance ,low level output) or earphone
output(100mw,32 low impedance output),to make sure that the signal can be at the best and without any distortion.
Channel frequency set: To facilitate the large number of users using the system ,at the first channel frequency need reasonable set by group. the same place can t be used same frequency. Channel frequency set follow below: press SET key first display screen digital shines, then press button until get to right frequency, after 5 seconds ,the receiver will auto-save & lock the result of setup.
2.4V charging connector, it is to charge for 2AA 1.2V battery. The charging time depends on its capacity, it is advised to use the charging battery with 1500mAh,and its charging time is 10-12hours. (Operation of battery charger follow below:)
1.Plug the AC power transducer(AC to DC)into commercial power plug. Plug the AC 6.5mm into 12V charging input, the POWER lamp will be lighting.
2.Make sure that the 2AA 1.2V battery of receiver is charging battery withright polarity .Put the receiver frontal face to the user,plug into charging plug with right side. The corresponding charging lamp
CHARGE will be lighting ,the FULL lamp will be lighting after full charging.
3.It is advised to close the power of receiver when battery of receiver is charging. To avoid breaking down the inner component of receiver with high power.
