Notes on the FP's Liquid Crystal Display (LCD)
■ Depending on the type of information being displayed on the FP's screen, or the current
contrast setting, subtle variations in brightness may appear. This phenomenon is a
common attribute of LCD's and is not a defect.
■ There are minute grid-points on the LCD surface. These points are not defects.
■ Occasionally crosstalk (shadows appearing on extended display lines) will appear on
the display. This phenomenon is a common attribute of LCD's and is not a defect.
■ The displayed color will look different when viewed from an angle outside the speci-
fied view angle. This phenomenon is a common attribute of LCD's and is not a defect.
■ Displaying a single screen image for long periods of time can cause an afterimage to remain
onthe screen. To correct this, turntheunitOFFfor a short period(5to10minutes), then ON
again. This phenomenon is a common attribute of the LCDs, and not a defect. To prevent
the creation of an afterimage, you can change the screen display periodically to prevent the
displaying of a single image for a long period of time.
When the FP's Liquid Crystal Display (LCD) is Damaged
"If the FP's display is damaged or cracked, be sure to avoid any contact with the

The front face of the GP unit, installed in a solid panel, has been tested using condi-
tions equivalent to the standard shown in the specification . Even though the GP unit’s
level of resistance is equivalent to the standard, oils that should have no effect on the
GP can possibly harm the unit. This can occur in areas where either vaporized oils are
present, or where low viscosity cutting oils are allowed to adhere to the unit for long
periods of time. If the GP’s front face protection sheet becomes peeled off, these
conditions can lead to the ingress of oil into the GP and separate protection measures
are suggested. Also, if non-approved oils are present, it may cause deformation or
corrosion of the front panel’s plastic cover. Therefore, prior to installing the GP be
sure to confirm the type of conditions that will be present in the GP’s operating envi-
ronment.
If the installation gasket is used for a long period of time, or if the unit and its gasket
are removed from the panel, the original level of the protection cannot be guaranteed.
To maintain the original protection level, you need to replace the installation gasket
regularly.

Signal Names
Signal names used for the FP's serial interface are designed to match the pin
order used on most PC serial interfaces, so that a straight cable can be used to
connectthe two.Therefore,connect each pin's signal to the same signal name
on the PC connector.
Forexample, pin #2 'RD' should be connected to the PC's 'RD' pin (terminal).
Refertosection"2-4OptionCablePin Diagrams" for information about each
signal'sdirection.
