Power failure compensation circuit
This recorder is equipped with a power failure compensation
circuit. When the recorder is fully charged for 48 hours,
the date and time settings, timer recording settings, and
menu settings are retained for about 1 month without power
supply.
The clock accuracy declines if the power plug is not
connected to the wall outlet for a long time of period.
In this case, it is recommended to check the present time
setting.
Power failure recovery recording
When a power failure occurs during recording or archiving,
the recorder resumes operation after recovery from the
power failure. When a power failure occurs during timer
operation, the recorder resumes timer operation after
recovery from the power failure if it is within the timer
recording period. (The recorder may not be able to continue
recording after recovery from the power failure when an
error beyond recovery has occurred.)
Notice
• When a power failure occurs during recording, the
recorded data may be broken or may become unable
to be played back anymore.
• When a power failure occurs during recording, the
image and audio data stored in the recorder’s internal
memory cannot be transmitted to the HDD.
• In case of a failure in the recorder, it may not be able
to continue recording after recovery from the power
failure.
Tips
• When a power failure occurs during alarm or
emergency recording, the recorder resumes recording
after recovery from the power failure.
• The log of recording start operation (such as [REC
ON]) is not registered after recovery from a power
failure.
• In the data recorded by this function after recovery
from a power failure, playback images or audio may
be disturbed or the search function may not work
properly.
• Images recorded at the time of occurrence of a
power failure may be disturbed. When the pre-alarm
recording is enabled, the image recorded a specifi ed
pre-alarm time before preceding the occurrence of a
power failure may also be disturbed.
