Built-in backup battery

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 internal clock may keep bad time or the operative condition may be different to that before the electric power failure.

The built-in battery life is approx. 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 time and date 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 vulnerable to vibration. Handle them with care.

It is possible to damage them if they are moved while their motors are still running.

Do not move them just after turning the power off (for around 30 seconds).

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 oper- ation if they have been used at the recommended ambi- ent temperature (approx. +25 °C {+77 °F})

It is recommended to replace them after around

18 000 hours of operation to prevent data loss from disk failures.

When hard disk drive trouble occurs, replace it immedi- ately.

Contact your dealer about servicing.
