machine will ask you to restore the record by pushing enter button or abort by pushing
menu button, hard disk can automatically clear up if you push enter button and then resumes
to the status before power-off, and continue the interrupted recording. The time for hard
disk resetting and clearing-up depends on the recorded information on the hard disk, which
varies from ten seconds to a few minutes. So please wait patiently. If the machine stops
abnormally during playing last time, it does not need automatic recovery function.
2.Turn off the machine
 Normally turn off the machine when the system shutdown, which means do not to turn
off the machine while playing or system setting up, especially not to turn off the machine
while recording (otherwise the system will start automatic recovery function when turn on
next time).
 Push recording button to stop recording or push playing button to stop playing or exit
from system setup menu, then turn off the power.
 It is best to turn off the video-recorder power first, and then turn off the power of external
equipments.
 If do not use the video recorder for a long time, should pull out the power line from the
electrical outlet.
3.Ordinary recording
 Connect the power to all related equipments; ensure that there is video input.
 Push display button to check spare space of the hard disk, if there is no much space,

DVR-4 4-Channel digital Recorder
18
please think whether to change hard disk first or select overwriting modes.
 Check recording parameter setup before recording; select video quality, frame rate. Or
push quality button to select image quality, you cannot change record setting during the
process of recording.
 Manual recordings belong to ordinal recording. Under the manual mode (non-watch-on
status), you can choose certain channel image surveillance; here pushing record button will
record this channel’s single image video.
 Push the record button to begin recording, four channels will start simultaneously
recording.
 During the process of recording, if the hard disk is full, and the system is set to automatic
overwrite, then the recording will not be interrupted, and it begins to overwrite from the
earliest recorded area; if the system is set to overwrite disable, it will stop recording when
hard disk is full, the bottom right corner of the screen displays “*” which shows disk
overwriting.
 If the hard disk is used over 90% when you push the record button to record, the machine
will inform you by blinking massage. When over 99% of the hard disk while recording, the
char [M] which instand master hard disk or [S] which instand slave hard disk will blink.
4.Alarm recording
 Alarm recording is not started by manually pushing record button, all the recording
started by manually pushing the record button are ordinary record.
 Alarm recording can be activated by alarm input signal, so it is a must to check whether
the connection of alarm input equipment is correct, stable and reliable before turnning on
the machine.
 The prerequisite condition of whether the alarm recording can be activated by exterior
input signal or the changes of exterior environment is that the system must be set on guard
and that period is set to “S” in record schedule setup, also, that channel must not be set to
“NOT-INSTALLED” in sensor setup.
 Under the state of off-guard, system will never start alarm recording. Setting guard on or
off is achieved through pushing the alarm button on the front panel, but not through system
setup menu and window. Under watch-on situation, the character “alarmed” will display on
the screen. You can push the display button to clear the character.
 Alarm video recording can not stop by pushing record or stop button, but can stop by
removing guard. Because once the system is set on guard, the guard cannot be removed
randomly, so there is a password protection to remove guard, only after inputting correct
password, you can take guard off.

DVR-4 4-Channel digital Recorder
19
 Check alarm recording setup before recording, confirm the video quality and the frame
rate, the record setting cannot change during recording process.
 In the process of alarm recording, any buttons do not work except alarm, schedule,
display and channel select button.
 As long as the alarm input signal is effective, the alarm recording continues. When the
alarm input signal loses efficacy, the time set up by “SENSOR RECORD TIME” becomes
effective, and when the time goes out, the alarm recording automatically stops. In course of
this, if you want to manually stop alarm recording, the only way is to first remove guard
(answer the password).
 While the hard disk is full, it automatically overwrites the hard disk.
5.Time recording
 Time recording starts and stops recording automatically according to the pre-arranged
time period. It is applied to fixed timetable, for example, the periodical work time recording
(or off time recording) with fixed start/stop time.
 Once timing recording function is set, it will work simultaneously on four channels, that
is to say, four channels recording can only use the same timing setting, simultaneously
starting and simultaneously stopping.
 To start Time recording function, besides making record schedule setup beforehand, must
push down the schedule button on the front panel. While pushing down this button, the time
recording symbol “SCHEDULED” will display on the screen. You can push the display
button to clear the character. Without pushing the schedule button, the Time recording
parameter setup will not work.
 In the process of alarm recording, no buttons work except alarm, schedule, display and
channel select button. In time record state, you can repush schedule button then enter
password to stop time recording.
 Because Time recording is correlated closely with time, so before using this function,
should previously adjust the time.
 While the hard disk is full, it automatically overwrite the hard disk.
6.Playback
 In the stop state, push play button，system begins to play the images recorded most
recently.
 In the stop state, push play button will always play the images recorded most recently, no
matter ordinary video or alarm video.
 In the process of playing, push pause button to pause playing, re-pushing play button can
