5.2.3 Access to the SIM (Subscriber Identity Module) Card
When used in a GSM or iDEN network, each LMU uses a Subscriber Identity Module (SIM) card, which
should be inserted before you install the LMU for the first time. The SIM card is attached to the main-board
inside the housing of the LMU unit.
At some future time, you might need or want to replace the SIM card with a different one, so try to install the
LMU in such a way that the cover can be removed to make the SIM card accessible.
5.2.4 Protection from Heat
It is best not to place the LMU unit in an unusually warm location such as directly near heater vents, near hot
engine components or in direct sunlight. The maximum temperature that can be tolerated by the LMU is
described in the LMU Environmental Specifications section.
