(Only when the source is set to STANDBY) , , FM, AM keys are used to switch the display segments. , keys are

37、 used to switch the grids. (Forward and Reverse) FM, AM keys are used to switch the segments. (Forward and Reverse) 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 t

38、ime when Test Mode Standby is the source. This will make it possible to confirm results with presence-or-absence detection. MENU selection : DIMMER adjustment (NAVI ATT ON/OFF) (CODE STBY) Display of DC offset detec- tion presence/absence. Display DC Offset detected : DC Err DC Offset not detected :

39、 DC OK *The detection information in the EEPROM can be forcibly cleared by pressing or key for more than two seconds while the DC Offset detection (DC Err) is being displayed. In this case, the display will be for DC Offset not detected. (DC OK). MICROCOMPUTERS TERMINAL DESCRIPTION TEST MODE ? ? ? ?

Also, by ACC

43、OFF and POWER OFF, the Source of Tuner and Audio will go into the initial conditions. Forced clearing of DC offset detection Regardless of the Test Mode, when power is turned on by SRC key while depressing the following keys. This will be the forced clearing of DC Err condition in the EEPOM. This wi

How to delete registered security codes After resetting and entering the test mode again, in the screen for entering the security code,

45、continue depressing #6 key, while depressing #1 key. This will result in dis- play of the character “C” on the right side of the code input screen. Then, using 1, 2, 3 and 4 keys of the remote control- ler, input “KCAR”. The registered code will be deleted by confirming the input with S.A key.
