6. Failures
A
� Depending on the types of errors, one of the following error messages will be displayed when the unit is turned on:
EEP ERR
1. Breakage or short-circuiting of the communication line to the EEPROM can be suspected. 2. A failure in the EEPROM can be suspected.
OC ERROR
B
� If "OC ERROR" is not displayed when the unit is turned on in Normal mode, short-circuiting of the speaker terminals can be suspected. � If "OC ERROR" is displayed again when the unit is turned on in Normal mode, the following causes can be suspected: 1. One or more of the ICs among the three digital amplifier ICs (IC3201, IC3301, and IC3401: TAS5122DCA) on the MAIN Assy is in failure. 2. The line between one of the above digital amplifier ICs and the speaker terminals is short-circuited. 3. The XSD line from one of the above digital amplifier ICs to the system-control IC (PDC128A) is short-circuited by grounding or is broken.
OVERTEMP
C
� If "OVERTEMP" is not displayed when the unit is turned on in Normal mode, the unit is normal. (It is likely that this was a temporary temperature rise, lower the volume of the speakers.) � If "OVERTEMP" is displayed again when the unit is turned on in Normal mode, the following causes can be suspected: 1. One or more of the ICs among the three digital amplifier ICs (IC3201, IC3301, and IC3401: TAS5122DCA) on the MAIN Assy is in failure. 2. The OTW line from one of the above digital amplifier ICs to the system-control IC (PDC128A) is short-circuited by grounding or is broken.
7. DSP error display
� Each time the SOUND key on the remote control unit is pressed while the power is on, the DSP error display and the normal display are alternately switched.
U TEST
8. Accumulated power-on time display and speaker setting display
� If the AUDIO INPUT key on the main unit is held pressed for 8 seconds while the power is on, the accumulated power-on time display and the speaker-setting display will be alternately switched at intervals of 3 seconds.

� Power-on time is always counted while the power is on, regardless of unit's functions and operations. However, it is not counted during Standby mode. � The maximum countable power-on time is 255H59M (255 hours 59 minutes.) The indication will not advance beyond that. � The accumulated power-on time basically cannot be cleared.
