Reset Button

Software Reset: If you have any unexpected problems with your

DOT 400 software, click the Reset button on the bottom of your

DOT 400. Then you will see the initial display screen. The screen

will display the Microsoft Windows CE.NET logo, and it will display

the main window (If you have set your own password, the

password input window will be displayed. Once you enter the

correct password, DOT 400 will display the main window). In the

Software Reset mode, only currently running programs will be

closed. Although you may lose the current data or files, the data

and files saved previously will not be affected.

Hardware Reset: When there is a serious problem with DOT 400

which cannot be fixed by software reset, you must restart DOT

400 by hardware reset. Press-and-hold the Reset button for more

than 4 seconds to cut off the power supply of DOT 400. And then

click the Reset button again, DOT 400 enters into Hardware Reset

Mode and loads images in Flash ROM to SDRAM. In four or five

seconds, the D.O.Tel company logo and progress bar will start to

appear. You can check the loading status with this progress bar.

After the images are loaded, the main window appears.

1. When performing software reset, be aware that clicking the Reset

button for more than 1 second may trigger hardware reset..

2. In the hardware reset mode, all data, files, programs, and PIMs

data created in DOT 400 or transferred from your desktop PC will

be erased. To avoid data loss from unexpected problems, it is

recommended to backup all data and files created in DOT 400 to

desktop PC, and PIMs data to Flash ROM or CF Flash Memory card

(for more information, see PIMs Backup).
