Supercap Power Backup
To prevent data loss during battery replacement, the terminals have a supercap power
backup. The supercap backup provides sufficient power to preserve memory contents for
approximately 5 minutes while batteries are replaced. The supercap does not provide
enough power to operate the terminal. On receiving a low battery message, replace or
recharge the primary batteries immediately.
