# Fitting of the tool cable

- Make sure that the tool cable is of correct type.

- Align the cable connector using the two asymmetrically positioned heads on the connector to fit in the slots in the tool handle.

- Tighten the lock nut.

- Make sure that the connection is correct by pulling, pushing and turning the cable connector (there should be no movement).

The tool has a built in electronic memory chip that will transmit the torque transducer calibration value and angle pulses to the POWER FOCUS/drive unit. Any changes made of these values in the POWER FOCUS while the tool is connected will be stored in the tool memory.
