¾ Caution of Low Battery Charge
The battery pack is the only power source for the terminal to work. It also charges the
backup battery on the main board so that the data stored in SRAM can be retained properly.
Therefore, when the main battery charge goes low, replace the battery pack with a charged
one or charge it as soon as possible. Always save data before it is too late.
Warning! Data loss may occur with SRAM during low battery condition. Always
save data before running out of power or keep a fresh battery for
replacement.
