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.

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.

1. Readjustment of battery voltage threshold value Readjust the voltage with the following procedure.
(1) Start up the service tool (J-2507-037-1) test mode “appollo_service.exe” on the PC and connect the main block to the PC using the
USB cable. The following screen will be displayed.
At this time the remaining battery setting voltage threshold value written into the circuit board will be displayed on block 5.
At this time the remaining battery setting voltage threshold value written into the circuit board will be displayed on block 5.
(2) Provide the regulation setting voltage in table 5 from a DC regulated power supply to the battery terminal.
Next, when block 6 is clicked, the conversion value (threshold value) of the voltage value provided will be displayed.
Clicking block 7 in this condition will write a new conversion value (threshold value) to block 5’s “AD Level”.
Clicking block 7 in this condition will write a new conversion value (threshold value) to block 5’s “AD Level”.
(3) Provide the regulation setting voltage and write the conversion value (threshold value) for each step in table 1-5.

Caution: The threshold value (the conversion value corresponding to the voltage value) will be different for each set.
Precautions:
1. Apply a voltage accuracy of within
±
0.01V with minimum ripple for the voltage of DC regulated power supply.
2. Use a proofed (calibrated) measuring instrument to measure the voltage applied.
3. Do not apply solder directly on the battery terminal when applying voltage to the battery terminal. Use clips, etc.,
