If a Power Failure Occurs

If power is suddenly lost due to an outage or accidental unplugging, a built-in battery retains the user data settings and the Address Book settings. Any sent or received documents stored in memory are backed up for about 60 minutes.

During a power cut, functions are limited as follows:

  • You cannot send, receive, copy, or print documents.
  • You may not be able to make telephone calls using an external telephone, depending on the type of telephone you use.
  • You can receive telephone calls using an external telephone depending on the type of telephone you use.

Remark
  • To fully charge the built-in battery, it takes approximately 2 hours when the main power switch is on. If the built-in battery is not fully charged, the data may not be saved properly.
    Furthermore, charging of the built-in battery may stop if the machine enters sleep mode with the <Sleep Mode Energy Use> set to <Low>. During the approximate 2 hours it takes to fully charge the built-in battery, set the <Sleep Mode Energy Use> to <High> or prevent the machine from entering sleep mode by setting the <Auto Sleep Time> to <Off>.
