Install SIM cards
To install SIM cards:
1. Use a Philips #0 driver to remove the SIM slot cover.
2. For high-vibration environments, apply a thin layer of dielectric grease to the SIM contacts.
Note If the IX10 device is used in an environment with high vibration levels, SIM card contact
fretting may cause unexpected SIM card failures. To protect the SIM cards, Digi strongly
recommends that you apply a thin layer of dielectric grease to the SIM contacts prior to
installing the SIM cards. See Apply Dielectric Grease over SIMContactsApply Dielectric Grease
over SIMContacts for instructions.
3. Insert the SIM card(s) into the SIM sockets. Insert the end of each SIM card with the chamfered
corner positioned as indicated. Push the SIM in until it clicks into place.
4. After SIM cards are installed, use a Philips #0 driver to secure the SIM slot cover. Torque screw
to 2 in lbs (225 mN m) maximum.
Apply Dielectric Grease over SIMContacts
Note Digi recommends using either …the Loctite® LB 8423 Dielectric Grease or Synco Lube® Silicone
Dielectric Grease.
1. Use a sheet of paper or cardboard over the area where you intend to work.
2. Use isopropyl alcohol and a cotton-tipped applicator to gently clean the SIM contacts. Using
isopropyl alcohol requires a well vented environment. Demineralized water can also be used as
an alternative.
