· Display test mode To enter this mode : Operations :
Short the land TEST_3 on the pc board, then restart the unit. The pin 86 (TEST_3) of the IC804 will be shifted to H. Each time you press the 6 button on the remote control, the mode will change cyclically as follows: No display All OELs light up. Normal display
C
· Test mode To enter this mode : Operations :
Short the land TEST_2 on the pc board, then restart the unit. The pin 80 (TEST_2) of the IC804 will be shifted to H. When you press buttons on the remote control for each source, the test command will be sent out.
D
· Service test mode (only for the AXM-P7050/ES) To enter this mode : Short the land TEST_1 on the pc board, then restart the unit. The pin 62 (TEST_1) of the IC804 will be shifted to H. Operations : The power will be turned on automatically, and then the unit will start operations with the Analog2-RCA source. Confirm that the signal applied to the RCA input is put out from the RCA output. (The internal selector has been set to the RCA input.) This mode can be operated even without the display unit.

- Removing the OEL Unit
1. Apply hot air to the cable pins for the anode terminal using a blower used for removing a flat-packaged IC or something like that. When all the pins are peeling off from the PCB, pinch the cable with a pair of tweezers and remove it slowly from the PCB. (Fig.3) * Be careful not to remove other electrical parts when you use a blower . * Flexible cable may not remove easily by transforming the Bosses by the hot air of the Blower. 2. Four tabs are extended until becoming straight in the direction of the arrow and then remove the Holder. (Fig.3) 3. Slowly set up the OEL Unit. At this time, the stress is prevented from hanging to flexible cable in the Cathode terminal. (Fig.4) OEL 4. The Cathode terminal is removed according to the procedure Unit same as the Anode terminal, and the OEL Unit is removed. (Fig.4) 5. Remove the Holder. (Remove after removing the Cathode terminal without fail.) (Fig.4)

- Installing the OEL Unit
1. Install the Holder in the OEL Unit. (Fig.5) 2. When soldering the flexible cable for the Cathode terminal on the PCB, use a pair of tweezers. First, insert the tips of tweezers into 2 holes in the flexible cable, then into the 2 holes in the PCB. (Fig.5) OEL 3. Position the flexible cable on the PCB so that their lands Unit touch each other. (Fig.5) 4. Apply solder to each pin of the flexible cable. (Fig.5) * Appropriate soldering iron lightly so that the stress should not hang to Flexible cable. 5. Lay down the OEL Unit. (Fig.5) 6. Install the Holder. (Fig.3) 7. When soldering the flexible cable for the Anode terminal on the PCB, first, insert the Bosses on the PCB into the 2 holes in the flexible cable. Then, take the same procedures 2 and 3 as that for the Cathode terminal to solder the cable pins. (Fig.3) Fig.5
