10.3 Replacing Consumables
The hard disk, UPS battery and LCD backlight used in this system have a limited service life, so that they
should better be replaced periodically.
The expected service lives of these parts if the system is used constantly are as follows:
Number Part Nominal life Remarks
1 Hard disk Two years When the power supply is on constantly.
2 UPS battery Five years When the power supply is on constantly. If the
system is not used for long periods and battery
charging/discharging is repeated, then the nominal life
may be shorter.
3 LCD backlight Five years When the power supply is on constantly.
Please consult with the store, sales agent or our branch office, sales offices or outlets for replacing the
above parts.
