6.  Transitions in Each Mode
 

The TEST MODE is entered and the details of the Service 
Menu are as follows:

1

Function: To check the version of the relevant module.

PCM-M10:  Destination (US, CN(CND), CH, KR, E)
Boot:  

Boot loader F/W version

ARM:  

F/W version for CPU (ARM section) 

DSP:  

F/W version for CPU (DSP section)

Date:  

Date and time of build

2

Function: To allow you to check inputs by pressing the cor-

responding keys.

Input checks as well as INT check. (KEY confi rmation checks 
and KEY_WAKE interrupt check)
Target keys to be inputted:
[x STOP], [X PAUSE], [. FR/V], [ ] [MENU], [DE-
LETE], [  A-B], [DISPLAY], [M FF/v], [T-MAKE], [N 
PLAY/ENTER], [z REC], [REC LEVEL], [DPC (SPEED 
CTRL) ON/OFF], [POWER/HOLD], [VOLUME +], [VOL-
UME –]
[MIC SENS (ATT)] is excluded from these checks.

When an input has been determined, the backlight is illumi-
nated for 0.5s.
When all the inputs have been confi rmed at least once, OK is 
displayed on the LCD and the LED (GREEN) is lit. 
Use [x STOP] or [MENU] button to return to the menu.

When an input has been determined, the backlight is illumi-
nated for 0.5s.
When all the inputs have been confi rmed at least once, NAND 
is formatted (all the issues are deleted) and the MENU settings 
are defaulted. (However, LCD Contrast is held.)
When the formatting has been normally completed, the system 
is restarted (rebooted).

[PLAY]: 

  Starts Loop Back

[STOP]: 

  Stops Loop Back 

[VOLUME +/-]:  As per the volume control of the set 
 

  (initial value: 20).

[MIC/LINE IN]:  As per the set control.
[REC LEVEL]:   As per the set control.
[DPC]: 

  Audio out

 

  (OFF: HP OUT, ON: LINE OUT)

[HOLD]: 

  (OFF: LIMITER OFF, ON: LIMITER ON)

 

  MANUAL: “MUTE” is switched on or off  
  each time [T-MARK] button is pressed.

Input: 

  INTMIC, EXTMIC, LINEIN

Output: 

  HP (HP OUT), SP (SPEAKER), LO (LINE  
 OUT) 

5

Function: To adjust the contrast of the LCD.

The default (initial value) is taken as Value=XX (XXh).
(UI value: This is a value displayed in the TEST MODE.)
