FIXING AND REMOVAL METHOD
1. Match the direction of relay and soc k et.
2. Both ends of relays are fixed so surely
that the socket hooks on the top surface of
relays.
3. Remo v e the rela y, applying force in the
direction shown below.
4. In case there is not enough space for
finger to pick relay up, use screw drivers in
the way shown below.
