The PIM Master menu-driven interface is easy to use and requires little training. The PIM Master uses a touch screen and keypad for data input. The five bottom menu keys and eight submenu keys on the right side are touch screen keys. The menu and submenu keys will vary depending upon the selected mode of operation, refer to Mode Selector Menu.

Number keys 1 through 9 are dual purpose, depending upon the current mode of operation. The dual-purpose keys are labeled with a number on the key itself with the alternate function printed in blue above each of the keys. Use the blue Shift key to access the functions printed on the panel. The Escape key, used for aborting data entry, is the button located above number key 8. The four Arrow keys and the keypad can be used to change the value of an active parameter.
