NOTES:
1.
SMT = Surface Mount Technology
2.
All 250mA, fast-response fuses are installed in SMT fuse holders. Remove fuses gently with a small pair of needle-nose
pliers and slowly lift directly upwards. All power supply rail protection fuses are soldered directly to the PCB and, if blown,
should only be replaced by the factory during repair of the board.
3.
451 and 452 type fuses are manufactured by Littelfuse.
4.
452 type SMT fuses are time delay fuses.
5.
451 type SMT fuses are fast acting fuses.
6.
The parts listed in this appendix might become obsolete. Please contact Focal for advice on replacement parts.
