4. System Reset Button

 Pressing and holding in this switch for more than three seconds

performs a system reset.

Note: This switch is semi-recessed and must be pushed with a thin

object—such as the end of a paper clip or a ballpoint pen.

5. User Port 1 Switch

This switch selects which User Port 1 is active—the one on the front panel

or the rear panel. Set it to Front to activate User Port 1 on the front panel;

set it to Rear to activate User Port 1 on the rear panel.

6. User Port 1 (Maintenance Port)

This port is provided for convenient and easy access for system

maintenance. It shares the same function with User Port 1 on the rear

panel. By switching the User Port 1 switch to Front, User Port 1 on the

rear panel is deactivated and User Port 1 on the front panel is activated.

Use it just as you would any other User Port. (You must return User Port 1

Switch to the Rear position to reactivate User Port 1 on the rear panel.)
