causes of problems.  
1. Open the battery cover to install a 9V battery as per correct polarities.  
Move the power switch to ON position, the power indicator will be  
green to show normal operation. If the LOW BAT indicator indicator  
illuminates, this indicates the voltage is not enough for operation.  
Replace the 9V battery.  
6. Check that the volume is turned up on the instrument.  
If your amplifier still does not function, contact your local dealer or an  
authorized service agent.  
2. Plug the 3.5mm plug of supplied connector to screw-lock socket of  
transmitter. Plug the other end 6.35mm plug to your guitar output jack.  
3. ATTENUATION is for volume adjustment. Move it to 0dB position to  
get normal volume output, or to -20dB position to reduce distortion  
and avoid humming.  
4. If the system will not be used for a long time, please switch off the  
transmitter to avoid power consumption.
