1,Name and function of the front panel
Power light: It is on when it connects to electricity
Test point: Test the output of the level
Adjustment of the level:screw button ,screw the button to the required value
A/V set:Set the power ratio of the image and the sound carrier to the required figures.
FS : Adjust the volume
Modulation degree:to get the best video .
Name and function of the back panel
Video input: the video cable connects the signal source of the video
Audio input: the audio cable connects the signal source of the audio
IF output,IF input: connect these two ports with one IF line(attached) or another line between these two ports accepted.
RF output: RF cable connects any channel mixers
Power socket: Power line match the equipment power supply.More than one modulator works with ring series.Please check all the installment and connects and make sure all the things are right and then make the power up at least 10 minutes,then re-set the values of the equipment Note:Please avoid frequent power switch using.Please wait at least 1 minute before you re-start the equipment.
Safety notes
This modulator adopt the three-pin socket under 220V,50Hz power supply.Please make sure it is safe before you take the power on. The service man should full understand the sense of safety. Make sure all the new elements are the same model and size with the old ones(Power switches,fuse wires etc)when you are exchanging them
This product belongs to an accurate equipment.Please keep the humility and strong vibration away.
Care instruction
Please check all the problems with the below chart 1 when they occur.After check, it still cannot work.Please connect to our representatives in local or send the equipment to our company to repair.
Chart1 Problems
The solution
1 The light of the modulator cannot work: Bad power supply connection, lower voltage,fuse wire broken.Please connect the power supply correctly and exchange a new fuse wire.
2 Low output level of the modulator .Please re-set the value of the output level to the required value of the modulator
3 Bad images: Please re-set the value of the modulate degree to the correct one.
4 Worse sound carrier: Please re-set the A/V figures to the required value
One year warranty except the broken seal and the human damages.
