WHEN YOU TURN ON DVR & IT SUDDENLY MAKES BEEP SOUND WITH ERROR MESSAGE “SYSTEM TIME RESETTING (DB TIME)” ON SCREEN?
WHY IT HAPPENS..
WHEN DVR IS TURNED ON, IF SYSTEM TIME ON DVR HAS EARLIER TIME THAN TIME OF LATEST RECORDING FILE ON HDD, DVR GIVES THIS ERROR MESSAGE TO AVOID DELETING RECORDING FILE ON HDD.
EXAMPLE: DVR RECORDS FROM 17:30 AND DELETES RECORDING DATA BETWEEN 17:30~17:50 OF HDD. TO AVOID IT, DVR GIVE ERROR MESSAGE AND WOULD NOT START TO RECORD UNLESS DVR TIME RESETS LATER THAN 17:50
17:00 17:30 17:50
HOW THIS CAN HAPPEN..
- RTC BATTERY IS DISCHARGED (DEAD)
IF BATTERY IS DISCHARGED (DEAD), SYSTEM TIME GETS INITIALIZED TO YEAR, 1970.
IT MEANS, OF COURSE, SYSTEM TIME IS EARLIER THAN LATEST RECORDING FILE. AND DVR GIVES BEEP SOUND WITH ERROR MESSAGE.
TO CONFIRM BATTERY DISCHARGE, CLICK “OK” TO ERROR MESSAGE AND TURN ON/OFF A FEW TIMES. IF DVR KEEPS SHOWING THE SAME PROBLEM, IT IS BATTERY ISSUE.
- RTC (REAL TIME CLOCK) CHIP DEFECTED
WITH LITTLE POSSIBILITY THOUGH, IF RTC CHIP ON MAIN BOARD GETS DEFECTED, THIS PROBLEM CAN HAPPEN. RTC CHIP MAINTAINS REAL TIME WHEN DVR IS TURNED OFF.
- USED HDD IS INSTALLED
2 DIFFERENT DVR CAN HAVE DIFFERENT TIME EACH. SO DVR CAN MAKE BEEP SOUND WITH THE ERROR MESSAGE WHEN USED HDD IS INSTALLED.
NOTICE
IN MOST CASES, THIS PROBLEM IS CAUSED BY BATTERY DISCHARGE. ASK YOUR SUPPLIER MANUAL TO REPLACE BATTERY.
IF THIS PROBLEM HAPPENS TO YOUR DVR, DO NOT PANIC & CLICK “OK” BUTTON TO ERROR MESSAGE “SYSTEM TIME RESETTING (DB TIME)” THIS WON’T AFFECT THE RECORDING FILE.
YOU NEED TO MANUALLY ADJUST SYSTME TIME TO PRESENT TIME AFTER CLICKING “OK” AS SYSTEM TIME WILL GO TO TIME OF LATEST RECORDING FILE. EVEN AFTER REPLACING BATTERY, DVR SHOWS SAME ERROR MESSAGE WITH INITIAL TIME OF 1970. CLICK “OK” TO ERROR MESSAGE AND YOU ALSO NEED TO MANUALLY ADJUST TIME.
