- 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.4) * Be careful not to remove other electrical parts when you use a blower . Especially , when hot air is appropriated to the VR1902 too much, the volume will destroy. * Flexible cable may not remove easily by transforming the Bosses by the hot air of the Blower. 2. Five tabs are extended until becoming straight in the direction of the arrow and then remove the Holder. (Fig.4) 3. Slowly set up the OEL Unit. At this time, the stress is preOEL Unit vented from hanging to flexible cable in the Cathode terminal. (Fig.5) 4. The Cathode terminal is removed according to the procedure

same as the Anode terminal, and the OEL Unit is removed. (Fig.5) 5. Remove the Holder. (Remove after removing the Cathode terminal without fail.) (Fig.5)

- Installing the OEL Unit
1. Install the Holder in the OEL Unit. (Fig.6) 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.6) OEL Unit 3. Position the flexible cable on the PCB so that their lands touch each other. (Fig.6) 4. Apply solder to each pin of the flexible cable. (Fig.6) * Appropriate soldering iron lightly so that the stress should not hang to Flexible cable. 5. Lay down the OEL Unit. (Fig.6) 6. Install the Holder. (Fig.4) 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.4) Fig.6
