8. SERVICE PROGRAM
REMARK
If these service programs are set, All user preset memories will be cleared.
1. FACTORY mode (Tracking point memory)
This FACTORY mode can be use for measurement of the tuner circuit.
When the product is POWER ON, press both [ MEMO ] and [ DISPLAY OFF ] buttons simultaneously over 3 seconds.
FLD shows "FACTORY" for 3 seconds. Press [ PRESET ] button, FLD shows "PRESET SEL".
The tuning frequencies are memorized as follows.

2. FLD segment check mode
This mode is available to check all luminous segments by the following steps.
1. When the product is FACTORY mode ( Refer to above mentioned "1. FACTORY mode"), press [ DISPLAY OFF ] button. FLD
shows "SERVICE" for 2 seconds.
2. All segments and all LED light up for 5 seconds.
3. Each segment lights up step by step.
4. Press [ DISPLAY OFF ] button again, then this mode will be stopped and the product will be FACTORY mode.
3. Version of microprocessor (CPU)
This program is available to confirm the version of each CPU by the following steps.
QY01 (main) : When the product is POWER ON, press both [ CL ] and [ TREBLE
▼
] buttons simultaneously over 3 seconds.
FLD shows the version of program code for QY01.
Q691 (DSP) : When the product is POWER ON, press both [ CL ] and [ BASS
▼
] buttons simultaneously over 3 seconds.
FLD shows the version of program code for Q691.
4. Input and output test mode
This mode is available for the functions as shown in Fig 1 by the following steps.
1. When the product is FACTORY mode ( Refer to above mentioned "1. FACTORY mode"), press both [ MEMO ] and [ TREBLE
▼
]
buttons simultaneously.
2. FLD shows "AUTO D1". By pressing both [ MEMO ] and [ TREBLE
▼
] buttons simultaneously each time, the mode is changed
in the following order.

4.1. Input selection mode (without setting to system setup menu)
This mode is available to select the input without setting to system setup menu by the following steps.
1. When FLD shows "AUTO D1"( Refer to "4. Input and output test mode"), the input can be shifted by pressing [ MODE ] button
for the remote commander only each time as shown in Fig 2. ( [ MODE ] button is in page4 of AMP function for RC-18SR

4.2. 5.1 channels output mode
This mode is available to output the same signal from 5 channels, even though 2 channels audio signal comes in.
As the result, all channels output can be confirmed by using analog stereo signal or PCM audio signal.
AC-3 or DTS source is not necessary to output from any channel in this mode.
1. When FLD shows "ALL CH D1" (Refer to "4. Input and output test mode"), the input can be shifted by pressing [ MODE ]
button for the remote commander only each time as shown in Fig 3.
( [ MODE ] button is in page4 of AMP function for RC-18SR
*
)
2. Supply to 2 channels PCM signal for digital input or 2 channels analog signal for analog input. But, Left channel and Right
channel of input signal should be equal.
3. Then each output from the product is the same as the input signal. (Subwoofer channel is respond to lower than 80Hz signal)

5. Transistor MUTE mode
In mute situation on the product, output signal is muted by Volume control IC and muting transistor.
But, this mode is available to work the muting transistor only by the following steps.
1. When the product is FACTORY mode ( Refer to "1. FACTORY mode"), press [ MUTE ] button for remote commander only.
2. FLD shows "TrMUTE ON", then muting transistor circuit is active only.
6. How to reset the product
When the product is POWER ON, press both [ CL ] and [ DISPLAY OFF ] buttons simultaneously.
FLD shows "DEFAULT" for 3 seconds, then all memories are cleared.
Note
*
: The remote controller RC2000mkII is available instead of RC-18SR for [ MODE] button.
