Align pin 1 on the IC socket for a FP-144 system interface cable head into the IC socket on the user
system, as shown in figure 4.
2.2.3 Fastening Cable Head
CAUTION
1. Use the screwdriver provided for tightening screws.
2. The tightening torque must be 0.054 N•m or less.
If the applied torque cannot be accurately measured,
stop tightening when the force required to turn the screw
becomes significantly greater than that needed when first
tightening. If a screw is tightened too much, the screw
head may break or an IC socket contact error may be caused
by a crack in the IC socket solder.
3. If the emulator does not operate correctly, cracks might
have occurred in the solder. Check conduction with
a tester and re-solder the IC socket if necessary.
