Because the data and files you save on the product are stored in random-access memory (RAM), it is extremely important that you maintain a continuous power supply to the product at all times. If the product runs out of power, all information you have entered is lost. Although the Windows CE operating system and programs are stored in read-only memory (ROM) and cannot be erased, any custom settings and programs you have added are lost.
The product uses a rechargeable lithium-ion battery, which supplies power whenever the product is not connected to AC power. Under normal operating conditions, the battery should last for up to 6 hours of continuous use without recharging. Battery life varies, however, depending on how you use the product.
When taking out the main battery, keep in mind that when the product is without power, data retention is guaranteed for only 1 minute, and only if the backup battery level is â€œgoodâ€ on the Status tab of the Power panel. You do not need to take out the main battery except to replace it with a spare battery (F1287A).
