Quick Reference C–3
■ If the computer has a wireless device or a cell phone device
installed, such as an 802.11b/g, a Global System for Mobile
Communications (GSM), or a General Packet Radio Service
(GPRS) device, the use of these devices may be restricted in
some environments. Such restrictions may apply onboard
aircraft, in hospitals, near explosives, in hazardous locations,
and so on. If you are uncertain of the policy that applies to the
use of a particular device, ask for authorization to use it
before you turn it on.
■ If you are traveling internationally, follow these suggestions:
❏ Check the computer-related customs regulations for each
country on your itinerary.
❏ Consult with Customer Care about power cord and
adapter requirements for each location in which you plan
to use the computer. Voltage, frequency, and plug
configurations vary.
Å
To reduce the risk of electric shock, fire, or damage to the
equipment, do not attempt to power the computer with a
voltage converter kit sold for appliances.
