Other convenient functions

Power failure compensation circuit

The unit is equipped with an internalized power failure com-
pensation 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 accu-
racy of the time will decline if the power plug is not con-
nected to the wall outlet for and extensive period. In this
case, it is recommended to check the current time setting.

Power failure reset recording

If there is a power failure during recording or when turning
OFF the MAIN switch, the recording will resume after the
power is restored. If there is a power failure during timer re-
cording, the recording will resume after the power is restored
when within the set time period of the timer. For alarm re-
cording, recording will stop even within the set recording time.
The playback video at the start position where re-
cording is resumed after a power failure may be disturbed
and the search function may not operate properly.
Log function for 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 the MAIN switch on the rear
of the unit is turned OFF, up to 1000 items (including the
time of failure and warning log displays as well as other
warning items) are saved in the <WARNING LOG LIST>(
see page 58), and are displayed in red on the screen.

RESET button

When pressing the RESET button on the rear of the unit with
a ballpoint pen, etc., the unit is reset and the power turns off.
The menu settings, the current time and video data
are kept even when resetting the unit.

HDD SETTING

ALARM" can be selected for the HDD recording mode
( see page 19).
Setting ( default : "NORMAL" )
"NORMAL", "MIRRORING", "PARTITION",

MIRRORING

By saving the data in duplicate on two HDD's with the
same capacity, the risk of data loss due to an HDD crash
is greatly reduced.
