Opening the unit: high difficulty
- Read and written on the bench through the connector, with the housing closed.
- Units built after June 2020 are locked: bench unlocks without opening exist, but some methods still open the housing and unsolder a small resistor.
- The cover is glued with sealant and the board is bonded to the housing.
Advice: Keep it closed whenever the job can be done without opening it. If work inside the unit is needed, leave it to someone who opens this unit regularly.
General information: units with the same name can differ. Follow your tool's connection guide.
