Connection to any communication line other than an analog phone line 
could cause a PC system failure.
Connect the built-in modem only to ordinary analog phone lines.

Never connect the built-in modem to the digital connector on a

residences or offices. 
Never operate your PC on AC power during a thunderstorm. If you see 
lightning or hear thunder, immediately turn off the PC. An electric surge 
caused by the storm, may result in a system failure, loss of data or 
hardware damage.
