Unable to change parameters on CAL 3200, 3300, 9300, 9400 or 9500
If you cannot change the parameters in one of the levels on a CAL 3200, 3300, 9300, 9400 or 9500, check that you do not have a “lock” on that level. The lock is located in the hidden level 4.
To access level 4, first to to level 3 and at the parameter “UEr”, press and hold down the UP and DOWN buttons for 10 seconds.
The first parameter in level 4 is “LoCk”. Change this parameter to have a value to “none” if you want to unlock all levels.
