1. Entry into test mode

Perform power ON after short-circuiting the TEST MODE pin of the MOTHER assy during power OFF or transmit ESC+TEST with the test mode remote control unit (GGF1067). The power will be switched on and AV controller test mode will be entered. The standby LED of the main unit flashes during AV controller test mode. (Refer to Fig. 1.)

Entry into test mode
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.
1. Test Mode Use Conditions
Use of the test mode with connected DVD center unit is not possible. In that case, do not use test mode, but normal operation.
2. How to enter into test mode
With connection to an outlet and a display unit (or the remote control light reception jig), the power will be switched on and SF controller test mode will be entered when ESC+TEST is transmitted from the test mode remote control for LD servicing.
When there is a display unit
When there is a display unit, use is possible simply by connection to an outlet.

Display during test mode

After power ON, all FL are lit. Afterwards, TEST MODE is displayed except at the time of operation. The display at the time of operation is the same as during normal operation.
When there is no display unit
The remote control light reception jig (GGF1270) must be connected. Display at the time of operation is not possible.

How to leave test mode

When ESC is transmitted from the test mode remote control for LD servicing (GGF1067), the power is switched off. The same effect can be obtained when the plug is pulled from the outlet.
