¾ Caution of Data Loss
When the main battery is removed or drained, the backup battery on the main board is to
retain the contents of SRAM and maintain the running of the calendar for at least one week,
on condition that the backup battery has already been fully charged.
If the terminal is to be put away for a couple of days, you should be aware that data loss
occurs when both the main and backup batteries discharge completely. Therefore, it is
necessary to save data in a host computer before putting away the terminal.
Note: Being fully charged, the backup battery can last at least 1 week.
1.3.4 Keyboard
The terminal is equipped with a keypad of either 24 keys or 44 keys, which has
programmable LED backlight, for system setup, user entry and so on.
Silicon rubber has been chosen for their durability and prompt feedback. The key click can
be configured through the System Menu.
Note: Functionality of keys is application-dependent.
