Note: An alarm function is incorporated into this STP series. Alarm and cautionary messages are
displayed on the LCD of the display unit iDT-001 (optional accessory). Note that the words
"WARNING" and "CAUTION" displayed on the LCD indicate the need for overhaul of the
pump or precautions during the operation. They do not have the same meaning as the much
more serious symbols for "WARNING" and "CAUTION" used in the instruction manual.
