- 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
P.C.board, pinch the cable with a pair of tweezers and
remove it slowly from the P.C.board. (Fig.3)
* 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 direc-
tion of the arrow and then remove the Holder. (Fig.3)
3. Slowly set up the OEL Unit. At this time, the stress is pre-
vented from hanging to flexible cable in the Cathode termi-
nal. (Fig.4)
4. The Cathode terminal is removed according to the procedure
same as the Anode terminal, and the OEL Unit is removed.
(Fig.4)
5. Remove the Holder. (Remove after removing the Cathode ter-
minal 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 P.C.board, 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 P.C.board. (Fig.5)
3. Position the flexible cable on the P.C.board so that their lands
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 P.C.board, first, insert the Bosses on the P.C.board into
the 2 holes in the flexible cable. Then, take the same proce-
dures 2 and 3 as that for the Cathode terminal to solder the
cable pins. (Fig.3)
