updated to the latest one or if it fails to operate due to the data damaged.
WARNING: • Before updating the firmware, it is necessary to print the current func-

• Before turning off the power switch, be sure to check with the LCD
display that no PIX data and received data is stored in memory. Turning

lowing operation before turning on the power for operation. Unless the memory
is cleared, the firmware may not operate normally.
