Maintenance of the NT600S

its optimum condition.
Do not attempt to take the NT600S apart and do not touch any internal parts while
the power is being supplied. Doing either of these may result in electrical shock.
Spare PT
It is advisable to have a spare NT600S available to minimize system downtime in
the event of an NT600S failure or if the screen display becomes difficult to read due
to deterioration of the display unit.

ily, replace the backlight. The backlight can be replaced at the rear of the NT600S

Guide to Backlight Replacement
Under normal conditions it can be assumed that the backlight will need to re-

accordance with the environment in which it is used and it should be replaced
when it is getting dim and the screen is getting hard to read.
