The DG100-212 sets the conditions for the

signal Sound Check through the analogue

circuit, the A/D converter, the DSP-3 and the

When the Sound Check is started, the LED display

shows "81". The Sound Check has two conditions.

If the RECALL key is pressed when the LED

display shows "81", the LED display changes to

"82" and the condition changes to the next as

below.

81 : DSP3-1

82 : DSP3-2

Check the following items in each condition of

"81" and "82".
