The shutdown switch is used when the OS or application programs are

straying and the system can not return to the normal state.

You must not use this shutdown switch when the UP-5900 is running

normally. Use this switch only when the main power source is not cut off

even if the main unit power switch is set to OFF position. The UP-5900

is turned OFF and the hardware is reset by turning the main power

switch OFF and then pressing the shutdown switch.

The shutdown switch is a single shut type. (Normally OFF position)

The shutdown switch is a push switch. If it is pushed to ON, the UP-

5900 stops supplying the power when the power switch is set into

stand-by mode.

Note: The shutdown operation will be ignored when the power switch is

set to power-on position.

The system switches are used to preset various system configurations.
