To continue recording, press the button
once
again.
If you push the joystick down, recording will stop, the DVR will go to
Standby mode.
If trere is no more free memory,t
he DVR will automatically go to Sleeping
mode
.
Record
ing
may be
saved
either in the cycle buffer mode or in the line
messages mode. The DVR can provide some memory size to the
cycle buffer. (See Profile setting)
Warning!
When recording into the cycle buffer (cycle record), the
DVR will start recording into the record beginning (i.e. deleting the
previously recorded data), as soon as the provided memory space
comes to the end. The time of the current record will go on, but the
remaining memory size will stay constant on the display.
Each record
ing
made is marked with the time and date by means of the
built-in real time clock.
You may adjust your DVR (see Setup mode) to record in the VAS
mode. This will allow you to compress the pauses in messages
efficiently therefore the
available
record
ing
time
increases
. Using this system
saves memory in pauses, but stores information about time intervals.
The pause length can be restored at further file processing with the
14
supplied software.
In the VAS mode, while recording into flash memory, the Record
symbol will be lit on the display. If the signal does not exceed the fixed
level, and it is not recorded into flash-memory, there will be Record and
Stop symbols on the display
You can make the VAS mode settings with the supplied software.
The VAS working algorithm is as follows: the DVR controller sleeps for
T1 time, then it switches on for T2 time and analyzes the signal. If it
discovers X1 threshold exceeding by the signal during this time, the
controller attempts to discover X2 threshold exceeding by T4 time
during T3 time. If the controller succeeds, the record starts, otherwise
the recorder continues sleeping. The record stops, if the signal does
not exceed X3 threshold during T5 time. And so on, in cycle. The user
can set T and X values corresponding to software settings to conform
to specific requirements.
Playback mode (PLAY)
When you push the joystick down, PLAY will appear on the display. If
you want to playback any record, press the push button to confirm
choosing the Playback mode. Push the button right or left to select the
record number to be played. Then press the button, and the playback
of the chosen record will start. The display will show the following
information (Fig. 3):
- In the symbol line battery charge indicator and mode symbol;
- In the numeric line on the left: playback time (hours and minutes), the
separator blinks at a 2-second interval, on the right: volume level;
- In the alphabetic line on the left: the size of the record segment
played, as the percentage of the total record size, on the right: the
number of the record being played.
