backlight operation. For the procedure on how to replace the

can prolong the life of the backlight by using the screen saver and
reducing the backlight intensity.

You can check the number of hours that the terminal has been in
operation by selecting Terminal Diagnostics from the Terminal
Configuration screen. Then select the Hours Logged tab. For details,
