Important: If the MediaChecker has already been

calibrated to the selected cable type, “CAL”

appears on the second line of the second

display shown at power-up. This display

appears for about 3 seconds before testing

begins. To erase this calibration and use the

factory settings, remove all cables from the

MediaChecker, press C D until “YES”

appears; then press E.

Press E anytime (except in setup mode)

to see the calibration status for the currently

selected cable.

on the attached cable and displays the measured

cable length, and then press E.

These cable parameters are stored and remain in

the cable type.
