1. Be sure to remove the battery from this set. (The power is supplied via USB cable) Operating the set in the Test mode with the battery
loaded could clear necessary information.
2. If operation check was performed for inspection, execute “Play Info Initialize” in qd (see page 7) to return respective functions to
initial positions (see Table 1-5 on page 7). In such a case, record current position of each function before executing “Play Info
Initialize” in qd , if necessary.

Work Procedure
Preparation:
1. Make sure that no battery is loaded in the set.
2. Start up the test mode “appllo_service. exe” of the service tool (J-2507-037-1 ) from the PC, and check that the following screen
    appears.
3. Connect PC to this set with a USB cable. Check that the block 1 of the following screen “open”, and “1PC” is displayed on
the LCD of the set. (The block 1 will “close” if the set is disconnected again) At this time, a sine wave is outputted from the
headphone. Also, the model name is displayed in the block qd of the screen.
Note: If the block 1 does not “open”, the circuits in MAIN board will be faulty. Audio signals are outputted from
    the reference signal in  the DSP of the set.
