5: Care and Maintenance of Your
AirCard Modem
Rev 2 Feb.11
As with any electronic device, the AirCard modem must be
handled with care to ensure reliable operation. Follow these
guidelines when you use and store your AirCard modem:
•
Do not apply adhesive labels to the AirCard modem or
SIM card. This may cause the AirCard modem or SIM card
to become jammed inside the slot, or prevent it from being
inserted properly.
•
When not installed in your computer, store the AirCard
modem and SIM card in a safe place.
•
The AirCard modem should fit easily into your
computer's PC Card/ExpressCard slot or USB port.
Forcing the AirCard modem into the slot/port may
damage the connector pins.
•
Protect the AirCard modem from liquids, dust, and
excessive heat. (See the Environmental specifications on
page 53 for the maximum tolerances.)
•
For AirCard modem with external antennas, optimal
signal strength is usually obtained when the antenna is
pointing straight up. The antenna should bend easily at
the hinge. Do not forcefully bend the antenna.
