2. Special Operations during Test Mode Special operations during test mode
During AV controller test mode, the DVD player section can be operated with the single unit DVD remote control (component code $A3), which normally does not function. Also, when �ESC + TEST� is transmitted during AV controller test mode with the LD servicing test remote control, DVD test mode will be entered. The operation is equivalent to the operation for the single unit player DV-505. Power OFF is performed when �ESC� is transmitted with the LD servicing test remote control during DVD test mode.

Notes 2 How to select �VIDEO1 ANALOG� AUDIO2 � (VOL+) = VIDEO1 ANALOG How to select �VIDEO1 DIGITAL� (Switch once to VIDEO2 and then use VOL- to return to VIDEO1.) AUDIO2 � (VOL+) = VIDEO1 ANALOG � (VOL+) = VIDEO1 ANALOG � (VOL+) = VIDEO2 ANALOG � (VOL-) = VIDEO1 DIGITAL How to select �VIDEO2 ANALOG� AUDIO2 � (VOL+) = VIDEO1 ANALOG � (VOL+) = VIDEO1 ANALOG � (VOL+) = VIDEO2 ANALOG How to select �VIDEO2 DIGITAL� (Perform power OFF/ON after setting to the second of VIDEO2. At the time of power ON, �ESC+TEST� must be used to enter into test mode.) AUDIO2 � (VOL+) = VIDEO1 ANALOG � (VOL+) = VIDEO1 ANALOG � (VOL+) = VIDEO2 ANALOG � (VOL+) = VIDEO2 ANALOG When this setting has been made, VIDEO2 DIGITAL will be obtained by power OFF with the POWER button and power ON in test mode by �ESC+TEST�. Switching between video 1 and video 2 Audio analog input and digital input for video 1 and 2 can be switched with �VOL +� and �VOL �� on the main unit and power ON/OFF. How to select video 1 analog audio input Press �VOL +� on the main unit once at the time of audio 2 selection. How to select video 1 digital audio input Press �VOL +� on the main unit three times at the time of audio 2 selection. How to select video 2 analog audio input Press �VOL +� on the main unit three times at the time of audio 2 selection. How to select video 2 digital audio input At the time of audio 2 selection, press �VOL +� on the main unit four times, use the POWER switch on the main unit for power OFF (power OFF can be confirmed by the standby LED on the main unit changing from flashing to steady lighting), and transmit �ESC+TEST� from the test mode remote control for LD servicing for power ON in AV controller test mode, to switch to video 2 digital audio input. Video 2 analog audio input is selected at the time of power OFF.)

Function switching during test mode
As this unit has no function keys on the unit body, �VOL +� and �VOL �� on the unit body are used for function switching during AV controller test mode.

Switching of DVD, tuner, MD, audio 1, and audio 2
The DVD function is active at the time of test mode ON. When �VOL +� on the unit body is pressed, the function can be switched in the sequence of DVD = tuner = MD = audio 1= audio 2. When �VOL �� on the unit body is pressed, the function can be switched in the sequence of audio 2 = audio 1 = MD = tuner = DVD. Here, several seconds may be required for switching from DVD to tuner, tuner to DVD, tuner to MD, and MD to tuner. As key input is not accepted during switching, the function switching key should be pressed slowly and with slightly longer intervals. As there is no function indication, provide video or audio input and confirm that the function has been switched.

Automatic presetting of tuner and station memory
The contents of the station memory preset automatically when entering into test mode are shown below. ST1, FM 88.5 MHz ST2, FM 89.5 MHz ST3, AM 954 kHz ST4, AM 1062 kHz ST5, FM 88.0 MHz

DVD remote operation
The DVD player operates with the single unit DVD remote control (component code $A3). In the same way as at the time of normal operation, �ESC + TEST� from the LD service remote control can be used to enter into the same test mode as with the single unit DVD player. In this case, power OFF will occur with the next reception of �ESC�. Note 1 DVD = TUNER = MD = AUDIO1 = AUDIO2 = ......... At the time of the above switching, several seconds are required to switch from DVD to TUNER. When �VOL +/�� is switched during this time, the function will not be switched. Please wait several seconds before switching.
