Coomatec DVRCam Time Setting

Q: I have a dome camera, and it's working great I however I cannot get it 

to remember the time setting. I have downloaded the Time Setting 

application, connect the camera to the PC, long press the button, run 

the software and click save settings. After this if I connect the camera 

to the power adapter while the blue LED is on (it stays on after 

disconnecting the camera from the PC for about 5 seconds), it won't 

start recording. If I connect it after it switched off, it records, but 

the time is reset to 1980. How should this work?

A:
Sorry for a mistake to set up time, please follow as :
1. Connect the DVRCam to PC,  (Don't press the menu button)
2. When the "Removable Disk" appears, download the "Time setting" software and click save settings.

If still not ok, Please help to confirm:

1.Do you set the time with TF card inserted? If not, please try with TF Card inserted.

2.After plug power out, does the indicator still stay on about 3 seconds? If not, it is the problem of built in battery.

Thanks
