Crane only moves at slowest speed with all functions

Customer was operating MDT crane with remote, but all functions were slow.  Had the following icon on the display of the remote:

Crane was in P+ mode, which allows for greater capacity, but slows function.  On the remote this is controlled with ” A-B ” switch.

In the cab this is controlled by the gray button on the top of the left joystick.
