Managing the Main Battery Power
Data and files saved on the device may be stored in RAM memory; therefore, maintain a continuous power supply to
the device to help prevent data loss. The Power LED indicates the main battery power level. When it shows blue color,
the battery level is good for operation. When it shows orange color, the battery level is low. It is better to replace the
main battery with a fully charged battery. When it shows blinking orange color, the battery level is critical low. You
have to replace the main battery with a fully charged battery immediately.
Checking Battery Power
Power icons appear in the task bar at the bottom of the window.
Double-tap on the icon at any time to open the Power system
setting. The Battery tab opens displaying the charge status of both
the main and backup batteries.
Note
To manually check battery power, tap Start > Settings > Control Panel > Power.
Internal Backup Battery
WebDT 435 provides hot-swappable battery function; this prevents the device from being reset when you remove the
main battery pack. This battery retains RAM data and allows the real-time clock to remain operational for up to 10-15
minutes. If the device is left without the main battery pack for more than 10-15 minutes, the device will shut down
and the data in the RAM will be lost.
Note
Even if the internal backup battery fails, data and programs stored in Flash memory are
not lost. However, the device automatically reset when you install a fully charged battery
pack and you need to reset the clock.
