When you open HP-3700’s TOP BOARD to repair, you need two “HP-3700 STAY (repair tooI)”s to hold the board.
If you use two straight bars insteas of the HP-3700 stays, It may be dangerous because the bars may come off from the
board easily. So we recommend you to use this “HP-3700 STAY (repair tool)”.
It Is safety to use stays to both right and left sides respectively. When you change the location of the holes for the stays.
You can change the board position slightely.
When ordering, please use the following name and part code.
(Use **pcs. Do not use **sets when ordering.)

When existing PCB is 100V/117V version, note the following.
Differences between voltage versions are fuse rate and fuse labels.
When fuses and labels of specific voltage (100V/117V) are required, order separately, referring
to Table.Abelow. When using replacement PCB on 100Vor 117V version, be sure to change mark
on PCB as shown in Fig.A
