The backlight is lit for 0.5 sec. when a key input is accepted.
When all the inputs have been confi rmed at least once, format the
NAND fl ash memory (delete all entries) and set the MENU set-
tings to their defaults. (Hold the LCD contrast setting.)
* Once the NAND memory has been normally formatted, restart
the system.
3. Loop
Perform a ADDA LOOP BACK.
External mic input: HP/SP output change
HP INSERT: Change to L/H
ALC function: OFF
HP output is selected independent of whether HP is installed or not
when there is no external microphone (this is provided for anti-
howl back). Selection of HP or SP output is determined only upon
entry into Loop. There is no switching on the way.
[PLAY]: Loop Back Start
[VOL+], [VOL–]: Volume operation to set. (Initial value 20)
[DPC]: OFF: Sensitivity H, ON: Sensitivity L
[A-B]: External mic select (MIC IN t AUDIO IN)
4. SetMic Cal
Write the correction value for the level difference between L and R
channels of the internal stereo microphone into the NAND memo-
ry. With the L channel level as the reference, measure the R chan-
nel recording level. Then adjust the R channel’s ADC VOL level so
that the R channel level is equal to the L channel level.
* Make a mental note of the setting even when the battery has been
removed.
