7-1 Maintenance
Perform maintenance operations to maintain the PT in optimum condition.
Do not attempt to take the Unit apart and do not
touch any internal parts while the power is being
supplied. Doing either of these may result in elec-
trical shock.
@ Backing up Project Data
Always back up project data and store it in a safe place when the PT malfunctions and needs
to be sent out for repair, or when replacing the Unit.
@ Spare Units
Prepare a spare PT to allow quick recovery of the system at such times as when the PT
malfunctions, or the service life of the backlight has expired causing poor screen visibility.
@ Backlight
The backlight must be replaced when the brightness of the display backlight dims and the
display becomes difficult to see. The backlight cannot be replaced by the user.
Contact your nearest OMRON representative.
• Backlight Replacement Guidelines
Replace the backlight according to the following guidelines under normal conditions.
After 50,000 hours of use at room temperature and humidity.
The service life of the backlight will be especially shortened if used in a low-temperature envi-
ronment. Replace the backlight when the brightness dims and the display becomes difficult to
see.
7-1-1 Replacing the Battery
Use a lithium battery to back up data other than screen data, such as calendar, clock, and log
data.
The battery service life is approximately five years at 25
°C. The service life will be shortened
if the battery is used at higher temperatures. Replace the battery periodically, according to the
operating environment.
Keep a spare battery available, so that the battery can be replaced immediately when re-
quired.
