Keypad Hardware Features

Adjusting Contrast

On the back of the keypad there is a plastic potentiometer, adjustable with a flathead screwdriver.
This is used to adjust the contrast on the LCD display. If the Impulse drive and keypad were
purchased together , this adjustment has been made by IDC. Some adjustment may still be necessary
to accommodate a variety of lighting conditions or viewing angles.

Remote-Mounting the Keypad

The keypad can easily be mounted and sealed to NEMA 4 specifications by using the included
mounting gasket and 6-foot communication cable. See Chapter 6, Hardware Reference, for
important information on mounting the keypad and extending cable length.

DIP Switch Settings

DIP-switch settings on the back of the FP100 keypad have no effect on either the keypad or the
Impulse drive.
