Restarting After Battery Change
After battery insertion, or if movement does not work correctly after battery setting, a reboot can be carried out by connecting the pad 1 with the pad 2 as we can see on picture below. Hold this position for 3 seconds to ensure the reset. This operation is far better than removing and reinserting the battery and thus ensures a correct restart of the movement.
After that, the movement is in the same configuration as after a battery change and an initialization procedure has to be carried out as described in user manual.
