Learning About the Power Supply and Backup Battery
The 246X terminal operates using an external power supply. It has a rechargeable NiCd
(Nickel-Cadmium) backup battery that is designed to back up all memory and the real-
time clock during a power loss. You must connect a power supply to the terminal for it
to operate. You must purchase the power supply separately.
Understanding the Backup Battery
The backup battery is a rechargeable NiCd battery that is designed to back up all
memory and the real-time clock during a power loss. The backup battery provides
protection for sags and dropouts.
Here are the features of the backup battery:
•
During a power loss, the terminal uses backup battery power to continue operating
for 10 seconds. If power is still not restored, the terminal saves all data and turns
off. However, if the backup battery charge is low, the terminal cannot protect the
data against a power loss and will turn off immediately.
•
The backup battery is rechargeable. The terminal continuously monitors the backup
battery voltage level and charges the backup battery whenever the voltage level gets
low. The power supply provides the power to charge the backup battery whether the
terminal is turned on or off.
•
The backup battery will last for a minimum of three years before its capacity is
reduced. Battery life depends on the age of the backup battery and your usage.
Using the terminal in extreme environments (very hot or very cold), reduces battery
life and will require you to replace the backup battery more often.
•
The backup battery provides backup battery power for a minimum of 2 weeks if the
battery is fully charged and no AC power is supplied. If you plan to store the
terminal for a long period of time, save any data stored in RAM to another drive on
the terminal.
If the backup battery has remaining power when you reconnect it to the power
supply and turn it on, the terminal resumes exactly where it was when you turned it
off, or it restarts your application.
Note: If the Resume Execution command is set to resume allowed, the terminal will
resume the application when you turn on the terminal. Otherwise, the terminal
boots and the application restarts.
