9. USB test � When the menu starts the USB self-check, either presence or absence of the Vbus is judged. (Vbus is present: �VBUS: ON�, Vbus is absent: �VBUS: OFF�) � The USB driver always works regardless of presence or absence of the USB signal only when Vbus is available during the USB test. At this time, turning on HOLD causes the set to move to the suspend state. Turning off the Vbus causes the set to return to the test menu. When Vbus is supplied with the menu displayed, the key will be inoperative. Be sure to press x�B key before supplying.

Menu reset � Pressing the x�B key causes the set to enter the menu initialization standby state. � Once all the keys below are input in this condition, the EEPROM will be initialized (The settings in the menu and the user name will be defaulted.).
