Functions of the unit in case of power failure

Power failure compensation circuit

The unit is equipped with an internalized power failure
compensation circuit. When the unit has been charged for 48
hours (full), the date, time, timer record settings, and menu
settings are kept up to 1 month without power. The accuracy
of the time declines if the power plug is not connected to
the wall outlet for and extensive period. In this case, it is
recommended to check the present time setting.

Power failure reset recording

If there is a power failure during recording, the recording
resumes after the power is restored. If there is a power failure
during timer recording, the recording resumes after the power
is restored when the present time is within the set time period
of the timer. For alarm recording, recording will stop even the
present time is within the set recording time.
When the power failure occurs during recording, the
recorded data may be damaged or playback of data may
become impossible.
When the power failure occurs during recording, the
picture and audio of up to 6 MB just before the power
failure are not recorded. When the pre-alarm recording
time is set to other than 0 second, picture and audio of up
to 32 MB are not recorded.
When the power failure occurs during alarm or emergency
recording, alarm or emergency recording is cancelled
after the power is restored.
"REC ON" is registered in the system log list when the
recording is started, but it is not registered when the
recording is resumed after a power failure.
The playback picture at the start position where recording
is resumed after a power failure may be disturbed and the
search function may not operate properly for that position.
Log function when power failure occurs while
the unit is in operation or the MAIN switch on
the rear of the unit is turned OFF
In the event of power failure or if the MAIN switch on the
rear of the unit is turned OFF when the power is supplied, up
to 1000 items (including the time of failure and warning log
displays as well as other items) are saved in the <System
Log List>. ( page 73)
