TR5823

(3) How to cut off the fuse

Cut off

4 mm 4 mm

Use sharp pliers to cut the fuse. A

tweezers, exerting a stress on the fuse.

(4) Replacement procedures

(7) Remove the connector barrel by turning the outer ring counterclock-

^ wise.

Remove the blown fuse.
Insert the fuse (which is cut out as described above) into the small

hole in the center of the connector barrel.

(Insertion is made

easier by rotating the fuse or the connector.)

Guide  the  slit  on  the  BNC barrel to the stopper  on  the  TR5823 con
nector  body  and  insert  the  fuse  into  the  central  hole  in  the  connec
tor.
Gently  turn  the  outer  ring clockwise.
Tighten the  ring.  Care should be  taken  not  to  overtighten.
