SEN0161-V2 pH Meter Calibration

Hi there I went through the calibration page as described in the wiki for the pH meter but there are no responses from the calibration functions when enter the calibration commands such as <<Enter Calibration Mode>> and others described in the Wiki. I see nothing. Do I need to erase the old calibrations first?

Please note that I am entering the correct enterph and calph commands, but I am getting no responses.
