How to enter the test mode
• In order to enter the test mode, while pressing down [ATT]
+ [WOW] keys simultaneously, press [SRC] key.
• The test mode starts up when STANDBY source is selected.
• The volume value is -10dB. (30 on the display)
●
Test Mode (Display)
• Since the display has many segments, it is possible to con-
firm on the bridges with other segments. (Only when the

Test mode
(Display of DC offset detection presence/absence)
• When in this mode, the mode for “Display of DC offset de-
tection presence/absence” will be added in the MENU items
at the time when Test Mode Standby is the source. This will
make it possible to confirm results with presence-or-absence
detection.
