Remarks:

Users can press button" Length" to adjust transmission distance of this device automatically or manually. If users do not press this button when power on, then the device will work like last time because of memory function. If users press this button after power, on the first two press will make the device adjust the distance according to the network cable length automatically. After this two press, if users continue to press this button, then will go to the mode of adjusting transmission distance (the 12 levels to tally and adding one more press means a new level. When users finish the 12 levels adjusting manually it will be back to adjust transmission distance automatically mode and into the new loop.
