7.1.1 TEST MODE

1. Conditions During Test Mode
• During Test mode, the unit will not be shut down for an emergency even if one of the failures mentioned below occurs.
• After the unit has been shut down in Normal mode for an emergency upon detection of one of the failures mentioned below,
you can turn it on immediately, without waiting for one minute, in Test mode.
2. How to enter Test mode
• Immediately after the power is turned off (within 5 seconds after the "-OFF-" indication goes dark), simultaneously hold the
AUDIO INPUT and STANDBY/ON keys on the Display unit pressed for more than 3 seconds.
• Test mode can also be entered in either of the following ways:
1. Connect the power cord to the wall outlet with the STEST port (microcomputer terminal IC5501: 43-pin) at High (5 V).
(See "Test mode connecting point".)
2. Connect the power cord to the wall outlet while holding both the AUDIO INPUT and STANDBY/ON keys on the Display
unit pressed.
Note: If the power cord was disconnected immediately before, be sure to wait at least one minute before turning on the
power in the manner mentioned above. Otherwise, the unit may not operate properly.
3. How to quit Test mode, and conditions for quitting
• To quit Test mode, press STANDBY/ON key and turn the power off.
• When Test mode is quit, only data on failure in RAM will be initialized, and data on user settings in RAM will not be
initialized.
4. Indications on the FL display when Test mode is entered
• The function setting will be COAXIAL input.
• The indication on the FL display when Test mode is entered will differ depending on whether the unit was shut down
normally or with an abnormality detected, as shown below:
• ADV mode will become 5-channel STEREO so that multichannel output can be obtained.
