Restoring Your Unit to Normal Operation
12. Connect your unit to a power outlet using the provided USB power
adapter. This will ensure that your unit remains powered on during the
whole recovery operation.
13. Tap FACTORY RESET to launch the recovery operation. If you prefer
not to perform the recovery operation for the moment, tap CANCEL to
simply start the unit without making any changes.
CAUTION
DO NOT TURN OFF your unit while the recovery operation is
underway. Doing so may damage your unit. Damaged units will
need to be sent back to EXFO for repair.
