1.4.23 Change Ready LED light intensity in sleep mode
This function is to set the Ready LED status in sleep mode whether to turn it OFF completely
or light it at low light intensity. The setting applied is reversed each time this mode is entered.
The setting currently applied can be determined by pressing the [Go] button ten times and
checking the LED status after several seconds. (Although all LEDs light after several seconds
after the [Go] button is pressed ten times, determine the setting by the status of the Ready
LED.) When the setting is completed, the machine returns to the ready state.
1.4.24 Firmware Installing mode
This mode is used to Install the firmware (sub firmware, main firmware).
Refer to
"1.1 Installing Firmware (Sub Firmware, Main Firmware)" in Chapter 4 for the
detailed procedure.
1.4.25 Enter maintenance mode for service personnel
Drivers of the same number of virtual USB devices are required for the computer to recognize
the USB-connected terminals. If the machine is connected to the computer at each time any
repair work is performed, virtual USB devices of the same number of the repaired machines
are automatically configured on the computer. To prevent numerous virtual USB devices from
being configured, entering maintenance mode for service personnel enables your computer to
identify multiple terminals via one single virtual USB device.
Enter this mode when using the download utility or service setting tool by installing the
maintenance driver.
