3. AUDIO block operation
This mode tests the AUDIO circuit by DSP LOOP operation.
When earphone is not inserted into earphone jack, SP-AMP is turned ON. When it is inserted into earphone jack, SP-AMP is OFF and HP-
AMP is ON.
Pressing of the ERASE key turns MUTING ON or OFF.
Pressing of the VOL + key or VOL – key allows the volume value to be controlled.
The MIC sensitivity can be changed LOW or HIGH by operating the MIC SENS switch. There is no display.
The VOR threshold level is shown by the red LED indicator that lights with AUDIO present.

In this mode, the waiting current and the WAKE UP circuit can be checked during SLEEP mode.
This SLEEP test is executed about 1 second after the Bx key is pressed. There is no operation selection display.
The display depends on whether the HOLD switch is ON or OFF.

7. A/D KEY voltage
This mode displays the CPU input voltages of KEYIN0 and KEYIN1 in hexadecimal (HEX) format.
Pressing of a specific key causes the corresponding voltage to be displayed.
In this mode, the x STOP key will display the corresponding voltage while it is being pressed. The display will be returned to the layer for
item selection by releasing the x STOP key. There is no layer (display) for operation selection.
