Attention: The ThinkPad T40 Series computer contains an authentication mechanism
If
you install an unauthorized wireless LAN Mini-PCI Card or RF CDC module that is not approved for
use in the ThinkPad T40 Series computer, the computer will not start, but only displays an error
message and emits beeps.
iii) The FCC RF safety requirement
The radiated output power of the Wireless LAN Mini-PCI Cards or RF CDC module authorized to use
for the ThinkPad T40 Series computer is far below the FCC radio frequency exposure limits.
Nevertheless, the ThinkPad T40 Series computer shall be used in such a manner that the potential for
human contact during normal operation is minimized as follows:
Caution: To comply with FCC RF exposure compliance requirements, a separation distance of at least
20 cm (8 inches) must be maintained between the antenna for the integrated Wireless LAN Mini-PCI
Card built in to the screen section and all persons. You are not allowed to disable “standby mode”
for the power management function, if you cannot maintain the sufficient antenna separation (at least
20 cm) in any case the LCD is left opened or closed.
