10. SIM CARD REPLACEMENT
The Cv3 utilizes an HSPA cellphone module that requires a SIM card to
operate on a cellular network. The SIM cardholder is located inside the
Cv3 therefore it is necessary to remove the top from the case in order to
gain access to the cardholder.
It is important to observe proper electrostatic grounding precautions
during this procedure.
Installation Steps:
•
Remove power from the Cv3.
•
Using a small Phillips screwdriver, remove the four black
aluminum screws around the base of the Cv3 metal box.
•
The top of the case containing all the electronics can now be
removed from the base of the Cv3.
•
The SIM card socket can be seen near the center of the board by
the cutout provided for the
antenna cable. Pressing it in
until a click is felt and then
releasing it ejects the SIM
card. The card will then pop
out or be free to pull out.
•
The new card is installed
with the gold contacts facing
down toward the board and
the wireless carrier’s logo
facing up. Press the card in until you feel a click where it
engages the locking mechanism. At this point, almost all of the
card will be inside the holder.
•
Replace the top of the case onto the base and secure with the four
screws.
•
The Cv3 should be ready for use.
Testing:
•
Apply power to the Cv3 and compare the PHONE and SIGNAL
indicators with the chart in Section 6.
