Operational Procedure
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.
(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”.
(3) Provide the regulation setting voltage and write the conversion value (threshold value) for each step in table 1-5.

Converted value (ref.)
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.,
to connect to the battery terminal.

Work procedure
2. Execution of Play Info Initialize
If the MAIN board was replaced for repair, execute “Play Info Initialize” in block qd to return respective functions to initial positions
(see Table 1-6).
Note: In executing the “Play Info Initialize”, set the slide switches to the following positions.
AVLS switch ..... NORM
HOLD switch .... OFF
3. Check after Work
(1) After work, check that the set operates normally through the operation in 1-3. “Operation Check for Inspection (Test Mode)” (see
page 3).
(2) Make sure that the check-out and check-in can be made using the PC applications “OpenMG Jukebox” (CODEC programs “MP3”
and “ATRAC3”) and “Windows Media Player 7” (CODEC program “WMA”). Also, make sure that the checked out data can be
played normally.
Note: Do not start up the “OpenMG Jukebox” and the “Windows Media Player 7” simultaneously.
(3) For an installation and acquisition method of “Windows Media Player 7” (CODEC program “WMA”), refer to the following
instruction.
