10. USB test
This mode provides VBUS ON/OFF display and SUSPEND test.
There is no layer (display) for operation selection.
The Bx key displays the VBUS status as “ON” or “OFF”.
With VBUS ON, turning the HOLD switch ON causes SUSPEND mode to be performed.

11. KEY proof-test
In this mode, counts are displayed by pressing a specific key.
It is possible to check how many times the key is pressed for KEY proof-test. Keys to be tested include slide switches (HOLD and MIC
SENS).
Counts are displayed to the upper limit of “999999” in decimal format.
However, the value will not be reset in this mode.
To exit from this mode, the power should be turned off.

12. MENU and FLASH MEMORY contents resetting
This mode initializes MENU information (including clock to be set) and all erases all the folders.
In order to complete this test, all the keys and all the slide switches must bee operated.
In control of keys and slide switches, their names a displayed.
The WAKE UP signal is also checked for tact keys. If any key or switch names are not displayed, the controls are faulty.
