Return jumper J11 to the normal position (one pin only).8. Reassemble the KPC-3 Plus and return to operation.Note: After a hard reset, all parameters are at factory default values and any mailboxmessages are lost.Calibration/EqualizationThe CALIBRAT command is used to assist in adjusting the data transmitter drive leveland also in adjusting the receive equalization of your KPC-3 Plus. The procedures listedbelow are a guideline for using the calibration command to adjust for optimumperformance.When you issue the CALibrate command, the following options will appear on yourscreen:CALIBRATE MODE:M send markR receiveS send spaceT send square wave- or + adjust XMITLVL while transmittingX exitPressing M will transmit a constant MARK (signal) until another key is pressed.Pressing R will measure a received square wave.Pressing S will transmit a constant SPACE until another key is pressed.Pressing T will transmit a square wave (space/mark) until another key is pressed.Pressing X will exit the calibrate mode and reset the KPC-3 Plus.Drive level.The drive level is set by a digital pot, providing a range of 1 mV to 4 V p-p. Default drivelevel is about 50 mV, corresponding to a XMITLVL command setting of 100. Afterentering the calibrate mode (CAL) you should use the T option to initiate thetransmission of a square wave and then adjust the AFSK drive level by pressing the ‗-‘
