MC-i3: Adding a Topcon SIM card – SIM installation and configuration (Part 1 of 2)

The following steps apply to the MC-i3:

  • Remove the eight (8) retaining screws from the base of the MC-i3.
  • Remove the base.

Note: When working with multiple MC-i3s at one time, be careful not to mix bases as the unit's serial number and other important information is marked on the label affixed to the base.

  • Insert the SIM card into the SIM card slot.
  • Reinstall the base and the eight (8) retaining screws using Blue Loctite and torque to 12 in-lbs.

Note: Failure to tighten all screws to the recommended torque may lead to moisture or dust entering the MC-i3.
