F. HOW TO CONFRIM ROM VERSION
Turn on the power while pressing “DOWN” and “MANUAL
SW” switches, and the model name appears as dG.S
for about 2 seconds and then the version number as *.**
also for about 2 seconds. (Each * represents a numeric
figure.) Read that number for confirmation. The normal
mode will then be resumed.
6: DSP Electric Characteristic
• Using the UP and DOWN switches, select “6” and
then press the STORE switch.The output level becomes
the same when the right end No. is “0” and when it is “1”.
• The output level, noise level and distortion rate can
be checked by inputting the signal for measurement
(by shorting the input with GND for the noise level check).
• Initial setting: HIGH/LOW SW (SW101) ••• OFF
(LOW), VR ••• Center, OUTPUT VR ••• MAX
