For Stimulators with touch screens, the Compact Numeric Keypad (MP3415) may be substituted for the Standard Keyboard to reduce desktop footprint. The user may then use the touch screen or the Keypad arrow keys (NumLock OFF) to select pacing protocols, stimulation channels and required extra stimuli, and may use the Keypad number keys (NumLock ON) for rapid adjustment or entry of numeric values. Starting and stopping stimulation / pacing can be done with the dedicated PACE key.
