2. Align pin 1 on the IC socket on the user system with pin 1 on the user system interface board,
and plug the user system connector of the interface board into the IC socket on the user system,
as is shown in figure 2.5.
Ensure that the locations of pin 1 on the socket and
connector are aligned before inserting the connector.
If this is not done in the case of the SH7125, power-supply
pins will be shorted as shown below.

1. Use a Philips-head screwdriver with a head-size matching
that of the screw.
2. The tightening torque must be no greater than 0.054 N•m.
If the applied torque cannot be accurately measured,
stop tightening the screw when the force required for
further tightening suddenly becomes significantly greater
than was initially required. Excessive tightening may
break the screw head or crack the IC-socket solder,
leading to an IC contact error.
3. If the emulator does not operate correctly, cracks may
have been produced in the solder. Check conduction
with a tester and re-solder the IC socket if necessary.
