Built-in backup battery • Do not expose the built-in battery to excessive heat such as sunlight, fire, etc. • Before the first use, charge the built-in backup battery (lithium battery) by turning on the power for 48 hours or more. If it is not charged enough, in a case where the power goes down, the operative condition may be different to that before the electric power failure. For example, the internal clock may keep bad time or logs may be lost. • The built-in battery life is approximately 5 years as an indication of replacement. (The built-in battery life may become shorter depending on the use condition.) Replace the built-in battery after 5 years of use. ("5 years of use" is just an indication of replacement. We are not providing any guarantee of the built-in battery lifetime.) When the built-in battery life runs out, some settings such as the date & time setting will not be saved once the power is turned off. • Ask your dealer when replacement of the battery is required. Hard disk drive (HDD) • Hard disk drives are precise devices. Handle them with care. It is possible to damage them if they are moved while their motors are still running. • Please be forewarned that any loss of information on the HDD is not guaranteed under any circumstances. • Do not move or install this product just after turning the power on or off (for around 30 seconds.) The hard disk drives are running. • The lifetime of hard disk drives is limited by use. Write errors may occur frequently after around 20 000 hours of operation, and the head and motor deterioration may occur after around 30 000 hours of operation. They will reach the end of their lifetime after 30 000 hours of operation if they have been used at the recommended ambient temperature (approx. +25 °C {77 °F}). • To prevent data loss from disk crashes, it is recommended to keep the ambient operating temperature at approx. +25 °C {77 °F} and to replace them after around 18000 hours of operation. • When hard disk drive trouble occurs, replace it immediately.
