A. Installation of the SIM Card in the SCM
(2) Clean the component interfaces and the adjacent area.
(3) Do an inspection of the component interfaces and the adjacent area.
(4) Remove the new SIM CARD from its packaging.
(6) Lift the SIM card holder and put the SIM card (4) into the SCM (3).
(7) Make sure that the metal contacts of the SIM card (4) point down.
(8) Put the SIM card holder back to its initial position.
(9) Apply Threadlocking Adhesive-- Low strength - (Material No.05BAA1) on the leading male thread of the screws (1) but keep the first thread free.
(10) Install the SCM cover (2) with the screws (1).
(11) TORQUE the screws (1) to between 0.08 and 0.06 m.daN (7.08 and 5.31 lbf.in ).
Subtask 23-28-32-865-059-A ** ON A/C NOT FOR ALL CAUTION:
OBEY THESE PRECAUTIONS TO PREVENT ELECTROSTATIC DISCHARGE (ESD) DAMAGE TO THE COMPONENTS:
(1) Make sure that you do not touch the metal contacts of the SIM card (4).- STAY ON A CONDUCTIVE SURFACE THAT IS ELECTRICALLY GROUNDED.
- USE A CONDUCTIVE WRIST-STRAP THAT IS ELECTRICALLY GROUNDED. (CONNECTED TO A BONDING-POINT NEAR THE WORK AREA).
- BEFORE YOU USE THE TOOLS, MOMENTARILY HOLD THEM AGAINST AN ELECTRICAL GROUND TO RELEASE STATIC ELECTRICITY.
(2) Clean the component interfaces and the adjacent area.
(3) Do an inspection of the component interfaces and the adjacent area.
(4) Remove the new SIM CARD from its packaging.
- Hold it at the end with the cut-off corner.
(6) Lift the SIM card holder and put the SIM card (4) into the SCM (3).
(7) Make sure that the metal contacts of the SIM card (4) point down.
(8) Put the SIM card holder back to its initial position.
(9) Apply Threadlocking Adhesive-- Low strength - (Material No.05BAA1) on the leading male thread of the screws (1) but keep the first thread free.
(10) Install the SCM cover (2) with the screws (1).
(11) TORQUE the screws (1) to between 0.08 and 0.06 m.daN (7.08 and 5.31 lbf.in )
. B. Remove the safety clip(s) and the tag(s) and close this(these) circuit breaker(s):
