23. Before using the SPMA function to change memory values in the PLC or transfer ladder
programming, confirm that the PT is operating. The SPMA function cannot be used un-
less the PT is operating.
24. Dispose of any battery that has been dropped on the floor or otherwise subjected to
excessive shock.
25. Dispose of the Units and batteries according to local ordinances as they apply.
26. When mounting the Battery, be sure to use the correct Battery and mount it correctly.
27. Do not disassemble or short-circuit the battery.
28. Do not connect a USB connector to any device that is not applicable.
29. Before connecting a USB connector to a device, make sure that the device is free of
damage.
30. Do not turn OFF the power supply to the PT while downloading or uploading screen
data or the system program. Doing so may corrupt the screen data or system program.
31. Periodically inspect the installation condition of the PT if it is being used in an environ-
ment subject to contact with water.
32. The whole system may stop depending on how the power supply is turned ON or OFF.
Turn ON or OFF the power supply according to the specified procedure.
33. Signals from the touch switches may not be input if the switches are pressed consecu-
tively at high speed. Confirm each input before proceeding to the next one.
34. To use numeric input functions safely, always make maximum and minimum limit set-
tings.
35. Do not use benzene, paint thinner, or other volatile solvents, and do not use chemically
treated cloths.
36. The PT uses an analog touch panel. Deterioration over time can cause the touch points
to move. Calibrate the touch panel if the touch points move too much.
37. Water resistance will be lost if the front sheet is torn or is peeling off. Do not use the PT
if the front sheet is torn or is peeling off.
38. The Rubber Packing will deteriorate, shrink, or harden depending on the operating en-
vironment. Inspect and replace the Rubber Packing periodically (approximately once
per year).
39. To use the NV3W in an environment with strong noise, connect the following noise filter
to the power supply line: RSEL-2001W manufactured by TDK-Lambda Corp.
40. A Waterproof Packing cannot be reused. To ensure waterproof performance, replace
the Waterproof Packing with a new one each time you reinstall the PT.
41. Screen burn-in will occur if the same pattern is continuously displayed for a long period
of time (24 hours or longer, as a guideline). To prevent screen burn-in, use a screen
saver or switch displays periodically (NV3W only).
