Figure 2-3. Warning Label on Encoder Cables
WARNING: When the Outer link cover is removed, you
see the label shown above. Do not remove the J3-ENC or
J4-ENC encoder cable connectors from their sockets. If
they are removed, the calibration data will be lost and the
robot must be run through a factory calibration process,
which requires special software and tools.
